5 Terminology: Standard Precautions “Standard precautions” has replaced the old wording “body substance isolation” (BSI) and “universal blood and body secretions”
6 Fentanyl Dosing for Adults Fentanyl dosing is changed and is now consistent for adults (< 65 YO) regardless of SOP2012 SOPs did not allow for a repeat dose of fentanyl for the adult suspected cardiac patient with chest pain2014 SOPs allow for a repeat dose of fentanylMust have a systolic BP > 100 mmHgPreviously, there was one dosing for adult patients with chest pain (suspected cardiac origin) that did not permit a repeat dose and another for patients with musculoskeletal pain that allowed a repeat dose. This is now consistent for all adult pain, allowing for a potential repeat dose. (see dosing details in following slides).Reminder: Providers should be reassessing vital signs in between and prior to medication administration.Note: This applies to adults < 65 years of age. For those 65 years of age or older, new dosages have been added to the SOPs
7 Fentanyl Dosing for Adults The initial fentanyl dose remains the same for all adult patients < 65 year olds1mcg/kg SLOW IV/IM, max 100 mcgAddition of one repeat dose0.5 mcg/kg SLOW IV/IM after 5 min, max 50 mcg
8 Fentanyl Dosing > 65 Years Old New dosing for patients > 65 years oldSlower renal clearance of drugsMore likely to experience adverse effects of opiates (even at lower doses)Initial and repeat dosages are the same, regardless of SOPMust have a systolic BP > 100 mmHg0.5 mcg/kg SLOW IV/IM, max dose 50 mcgRepeat dose 0.25 mcg/kg SLOW IV/IM, max dose 25 mcgReminder: Providers always have the option of contacting Medical Control with specific requests that are not in the SOPs. If providers feel the fentanyl dosing is not providing adequate pain relief and the patient remains stable, a request can be made to Medical Control.
9 Adverse Effects of Fentanyl AMS, respiratory depression(particularly if >65 YO)StuporDeliriumSomnolenceDysphoriaChest wall-rigidityMuscle rigidity (involving the respiratory musculature including the glottis)SeizuresDifficulty or inability to ventilate the patientMuscle rigidity (involving the respiratory musculature including the glottis) may also occur and further aggravate the respiratory depression associated with fentanyl therapy.Cases of seizures have occasionally been reported, but some investigators have suggested that the seizure-like events reported may have been episodes of fentanyl induced-rigidity.Both may have been related to cases of administering fentanyl too quickly; it is advised to administer fentanyl SLOWLY over 1-2 minutes IV.With chest wall rigidity you may experience difficulty or be unable to ventilate the patient. The treatment is to administer paralytic medication to paralyze the chest muscles until the fentanyl wears off. In the field without paralytics, continue making efforts to ventilate the patient by bagging. Do not perform a cricothyroidotomy, as this will not improve ventilation. Remember: this is not an airway problem, but a problem with chest wall compliance (movement) that inhibits exchange of gases (oxygen and carbon dioxide) in the lungs.
10 Adverse Effects of Fentanyl HypotensionBradycardiaNausea/vomitingConstipationArrhythmias (rarely)Hypersensitivity side effects including anaphylaxis have been reported on rare instancesClosely monitor the patient for adverse changes, especially in mental status and vital signs. Provide supplemental support per appropriate SOP if condition changes or deteriorates.
11 Pediatric Fentanyl Dosing Dosing for pediatrics has NOT changed1 mcg/kg SLOW IV/IM, max dose 100 mcgRemember: most pediatric dosages don’t exceed the adult dose!Obtain accurate weight from parents/caregiversNo repeat dose, but can call Medical Control to request additional dosing as appropriateNO IO route for fentanyl administration in pedsIf the patient requires an IO, stabilizing the patient takes priority to giving pain medication.Broselow tapes and other length-based resuscitation tapes are intended for use with pediatric resuscitations. The best method for obtaining a weight on a pediatric patient is to ask the parent or caregiver what their most recent weight was from their healthcare provider (such as physician) and when that measurement was obtained. Contact medical control if unsure as to the appropriate dose.Pediatric weights should be documented and relayed to Medical Control in kilograms. Since pediatric medications are based on kilograms, this is the standard. 1 lb. = 2.2 kgAs always, if the SOP does not allow for additional medications that you think are necessary, contact medical control with your request for physician consideration.
12 Fentanyl Administration Administering fentanyl too quickly can cause chest wall rigidityIV administration should be over 1-2 minutesIf using a saline lock, push the fentanyl over 1-2 minutes, then push the saline flush over minutes as well
13 Fluid BolusIn all SOPs, the phrase “Fluid Challenge” has been replaced with “Fluid Bolus”Administering a large amount of IV fluid in a relatively short period of time is a fluid bolus.Remember to reassess your patient after administration of each bolusVital signs, including pulse characteristicsLung sounds (crackles)Change in conditionFluid bolus correctly describes the procedure intended in the SOPs. Administering a large amount of IV fluid in a short period of time (5-10 minutes) is a fluid bolus.Remind providers that each fluid bolus administration requires reassessment, including new crackles in lung fields indicating fluid overload. Caution providers when administering fluid boluses to patients with pre-existing heart conditions (heart failure) and pulmonary conditions. Patients with heart failure should also be assessed for edema in their dependent extremities (lower legs and ankles). Pitting edema is present when an indentation persists after release of pressure to an area of the soft tissue.
14 Pleural Decompression “Pleural decompression” has replaced “needle decompression” throughout the SOPsReview with providers that pleural decompression is listed in NEMSIS as “respiratory: chest decompression” in the procedures section.LUMC has changed this so it now lists pleural decompression.Review the System-approved location and alternative site location for pleural decompression and the correct procedure, including a brief review of anatomy to avoid complications (compromising an artery or nerve).
15 General Patient Assessment Page 2Initial Assessment, BreathingAddition of “assess lung sounds”A reminder that auscultation of lung sounds should occur in the primary assessment stage of patient care
16 Zofran (ondansetron) Adult Initial Medical Care Page 4Adult Initial Medical CareZofran (ondansetron) may now be administered 4 mg tab ODT or 4 mg slow IV x1 dose.Patients must be actively vomiting and/or nauseous prior to administrationOnset of action of IV Zofran (ondansetron) is twice as fast as ODTAdminister over 1-2 minutes IV (no less than 30 seconds)
17 Zofran (ondansetron)Not approved for prophylactic administration (prevention) of nausea or vomitingCan only be given IV or ODT once – NOT both.ODT: patient should allow tablet to dissolve on their tongue for rapid absorption into the bloodstreamDo not have patient chew or swallow whole tabletZofran can only be given IV or ODT once – NOT both.If the patient throws up their Zofran (ondansetron) ODT and you physically see the Zofran (ondansetron) in the emesis, you can contact Medical Control to ask for direction. You cannot automatically administer IV Zofran (ondansetron)

19 Adult Suspected Cardiac Patient With Chest Pain Page 11Removed if “pain unrelieved by NTG”, administer fentanylAfter administering nitroglycerin (NitroStat) x 2 (ALS), administer fentanyl to achieve the goal of pain reliefThe goal is to alleviate all pain in the adult suspected cardiac patient with chest pain, as long as the patient remains stablePersisting chest pain or chest discomfort indicates persisting myocardial oxygen deprivation. The goal is to relieve all pain as long as the patient remains stable.Must have a systolic BP > 100 mmHgContraindicationsST-elevation in Leads II, III, aVF (inferior wall infarction which could result in severely decreased cardiac output if nitroglycerin is administered)Use of erectile dysfunction drugs within past 36 hoursContact medical control if patient is taking Brilinta (ticagrelor) due to possible decrease in efficacy of aspirin administration during a suspected myocardial infarction
20 Adult Suspected Cardiac Patient With Chest Pain Page 11Review the SOP (page 11) and focus on the new dosing for fentanyl administration.
21 Adult Pulmonary Edema (Due to Heart Failure) Page 21Lasix has been removed from SOPDose was not adequate for the purpose of diuresis that was needed for respiratory distress secondary to pulmonary edemaLasix was sometimes administered prior to nitroglycerin (not consistent with SOP)Nitroglycerin dilates coronary AND pulmonary vasculature, leading to relief of respiratory symptoms
22 Adult Pulmonary Edema (Due to Heart Failure) Page 21Review the SOP. Make sure providers understand the criteria of stable vs. unstable patients. Definite normotension (systolic BP > 100 mmHg).Supplemental High FiO2 Oxygen LPM non rebreather mask.For patients who are candidates for CPAP, they must be 1) STABLE (administering CPAP to a patient who is unstable, including altered mental status and insufficient respiratory control can result in a deterioration in the patient’s condition), 2) normotensive or hypertensive (systolic BP > 100 mmHg) and 3) meet at least TWO of the CPAP Inclusion Criteria. If patient is qualified to receive nitroglycerin (no contraindications), administer prior to initiating CPAP if possible. Don’t forget that nitroglycerin can be repeated every 5 minutes if the blood pressure remains > 100 mmHg and patient’s condition warrants it.
23 Adult Pulmonary Edema (Due to Heart Failure) Page 21Review the definition of unstable. Administering CPAP to an unstable patient can worsen the patient’s condition.Altered mental status: unconscious, unresponsive is more obvious; disoriented/confused to person/place/time, unable to follow commands or understandInstructions, talking about inappropriate things or conversation not about current situationSigns of hypoperfusion: altered mental status, pale/cool/clammy/diaphoretic skin, decreased or absent peripheral pulses, weak central pulses, hypotension, unable to obtain SpO2 due to poor peripheral circulation, peripheral cyanosis, central cyanosis, signs of shockReview erectile dysfunction and pulmonary anti-hypertensive drug names for recognition. These are possible contraindications to administering nitroglycerin. Contact Medical Control prior to administration.

Obtain 12-Lead ECG to rule out cardiac originstransient response ….patient responds but then relapses back to initial state of depressed respirations and decreased mental statusIn this SOP, Narcan (naloxone) is indicated by decreasing sensorium and pinpoint pupils, depressed respirations, and possible history of narcotic/synthetic narcotic ingestion. Narcan should not be given for general Syncope with no suspicion of narcotic ingestion.Per the Adult Initial Medical Care, a 12 lead should be obtained in any situation that could be cardiac-related. Syncope is often caused by a sudden decrease in blood pressure due to severely reduced cardiac output which can be secondary to a cardiac arrhythmia.

32 Adult StrokePage 32Now includes obtaining and documenting Last Known Well timeRequirement for hospital stroke center criteriaTime Last Known WellAsk the family for the specific timeRelay that time to Medical ControlGive that time to the emergency nurse in reportDocument the time in your run reportSection 7 criteria opening sentence reworded but the content is the sameReview importance of Last Known Well time. Time sensitive for thrombolytics and interventional radiology, so time Last Known Well becomes critical. The sooner prehospital providers can identify the precise time the patient was last known well and relay that information to Medical Control and the receiving hospital, the quicker the hospital stroke team can be activated and be prepared for the appropriate treatment.If last time seen was last night and now it is morning, that places the patient outside the window for thrombolytics and interventional radiology. There must be a defined time last seen. If bystanders are unable to provide a precise time, try to obtain a specific window in which the symptoms could have began.

The treatment is to administer paralytic medication to paralyze the chest muscles until the fentanyl wears off. In the field without paralytics, continue making efforts to ventilate the patient by bagging. Do not cric, as this will not improve ventilation.

81 Respiratory: Oxygenation vs Ventilation Region VIII EMS Systems
82 Objectives SME video of the month Describe the respiratory system and the process of breathingRecognize adequate vs inadequate oxygenation vs ventilation in patientsUnderstand the tools used for monitoring both oxygenation and ventilationDiscuss acute and chronic disease processes that effect oxygenation and/or ventilationDiscuss considerations for selecting the best device for delivering oxygen and ventilationsToday will be a review of cardiac SOPs, with several scenarios which will range from dispatch information (including actual recordings where available) through field treatment and include medical control communications as available. Some recordings will be simulated, or will be similar recordings obtained from public or internet sources.

87 Review of Respiratory System Breathing is only one of the activities of the respiratory systemThe body’s cells need continuous supply of oxygen for the metabolic processes necessary to maintain lifeThe respiratory system works with the circulatory system to provide oxygen and remove waste products of metabolism (carbon dioxide)Helps to regulate pH of the blood
88 Review of Respiratory System Every 3-5 seconds, nerve impulses stimulate ventilation, which moves air through a series of passages into and out of the lungsThere is an exchange of gases between the lungs and blood, which is called external respirationThe exchange of gases between the blood and tissues is called internal respirationCellular respiration (metabolism) is when the cells utilize the oxygen for their specific activities
89 Review of RespiratoryBreathing is primarily controlled involuntarily by autonomic nervous systemRegulation is largely r/t maintaining normal gas exchange and blood gas levelsReceptors in the body constantly measure the amount of oxygen (O2), carbon dioxide (CO2) and hydrogen ions (pH) to signal the brain to adjust rate and depth of respirations
90 Review of Respiratory98% of O2 is carried bound to Hemoglobin (the other 2% is dissolved in blood plasma)In summary, we breathe not only because we need O2 to survive, but to get rid of CO2, a by- product of cellular metabolism
91 Common Respiratory Diseases Obstructive Airway DiseasesChronic BronchitisEmphysemaThese 2 often coexist and are then termed chronic obstructive pulmonary disease (COPD)AsthmaStatus Asthmaticus is a severe prolonged asthma exacerbation that cannot be broken with repeated doses of bronchodilatorsTrue emergency, requires early recognition and may quickly lead to respiratory failure
92 Common Respiratory Diseases or Disorders Upper Airway InfectionsPneumoniaCan be viral or bacterialAdult Respiratory Distress Syndrome (ARDS)Respiratory failure with acute lung inflammation and diffuse alveolar-capillary injuryPulmonary Embolism (PE)Spontaneous PneumothoraxLung Cancer
93 Let’s start with the patent Airway . . . Head-tilt/chin lift ManeuverOpening the airway with repositioningJaw thrust without head-tiltOpening the airway if spinal injury is suspectedSuctionRemove secretions or debris
94 Airway Management Nasopharyngeal (nasal) Airway Maintain airway in a semiconscious patientOropharyngeal (oral) AirwayMaintain airway on an unconscious patient(no gag reflex)
95 Airway ManagementEndotracheal Intubation – patient can no longer protect airwayAdvantages:Provides complete airway managementHelps prevent aspirationPositive pressure ventilation can be givenControl of volumes of ventilationTracheal suctioning is possiblePrevents gastric distentionProvides a route for some medications (not preferred, but worst case if no IV/IO)High concentration of oxygen can be given
96 Airway Management Alternative Airways: King Airway Cricothyroidotomy Advantage is ease of useCan reduce time spent off the chest if CPR is ongoingCricothyroidotomySurgical or Needle, per system specific procedure
97 Airway ManagementTraits to look for in difficult to obtain airways (ANOTES):A: Awake patients (with a Glasgow Coma Scale score greater than 3)N: Neck (short or “no neck”)O: Obese patientsT: Trauma (facial, airway or requiring C-spine stabilization)E: EmesisS: Space: limited space about the head to manage the airway
98 Definition of Ventilation The process of air movement into and out of the lungsFor ventilation to occur, the following must be intact:Patent upper airwayNeuro control – brain stemMuscles of respiratory system, including diaphragm and intercostal musclesFunctional lower airway, including functional alveoli
99 Inadequate Ventilation Occurs when the body cannot:compensate for increases in O2 demandsmaintain normal oxygen/carbon dioxide balanceCauses:InfectionTraumaBrain stem insultNoxious or hypoxic atmosphere
100 Signs and Symptoms Respiratory Distress Respiratory Failure TachypneaUse of accessory muscles (intercostal, suprasternal or substernal retractions)Adventitious breath soundsNasal flaringTripod or position of comfortGruntingCyanosisDecreased level of consciousnessIncreased work of breathingPoor air entryDecreased breath soundsBradycardiaApnea or respirations less than 6 per minute
101 Respiratory Distress vs Failure Adventitious Breath Sounds:Respiratory Distress or Failure?1. Sounds that may accompany respiratory distress.2. Retractions in the child with probable croup, upper airway obstruction, displays respiratory distress. This could lead to failure if not treated appropriately.3. This child displaying Kussmaul respirations (often associated with acidosis, such as in DKA) is on the cusp of respiratory failure. Note the grunting, retractions (indicating increased work of breathing) and decreased level of consciousness is clear.
102 Causes of Respiratory Distress/Failure Failure to Maintain AirwayUpper Airway obstructionForeign bodyAnaphylaxis (laryngeal edema)EpiglottitisCroupTracheal traumaLower Airway ObstructionBronchospasmInhaled objects (foreign body aspiration)
103 Causes of Respiratory Failure Failure to VentilateFailure to OxygenateNeuroOpioids, sedative or anesthetic agentsBrain or spinal injuriesMuscularSteroidsMyasthenia Gravis (or other neuromuscular disorders)TraumaChest wall trauma such as flail chestPneumo-/hemothoraxPulmonary EmbolismPulmonary FibrosisInterstitial Lung DiseaseCOPDPneumoniaPulmonary Edema
104 Ventilation vs Oxygenation It is important to remember that these terms are NOT synonymousAdequacy of ventilation is evaluated using qualitative, external cues such as respiratory rate, chest rise and fall, compliance of a bag- valve mask
105 VentilationMany studies have shown that HCP’s tend to hyperventilate patientsBoth the rate and volume of assisted ventilations are often too highHyperventilation causes vasoconstriction which can lead to hypoperfusion to major organs (especially the brain)American Heart teaches that providers should administer ventilation at breaths per minute and titrate to achieve EtCO2 of 35-40mm/Hg using continuous waveform capnography
106 VentilationCapnography is a quantitative tool that can be used to monitor ventilation adequacy r/t end tidal CO2 concentration (EtCO2)Our medulla measures CO2 levels to adjust rate and depth of respirationsIf patient is having respiratory distress, the provider should measure CO2 to determine if breaths, whether spontaneous or artificial, are adequate
107 Normal CO2 level 35-45mm/hg Ventilatory failure (hypoventilation) Hypocapnia (CO2 < 35mm/hg)Hypercapnia (CO2 > 45mm/hg)Hyperventilation (blowing off too much CO2)Metabolic condition such as diabetic ketoacidosis or kidney failureHypoperfusionHypotensionShockHypothermiaMetabolism is slowed in hypothermic state, so less CO2 is producedVentilatory failure (hypoventilation)Narcotic overdoseStroke that affects the brainstemCO2 RetentionCOPDRespiratory AcidosisChest wall injuryChest muscle weaknessFever (hypercatabolic state)
108 CapnographyAmerican Heart defines capnography as the measurement and graphic display of CO2 levels in the airway, which can be performed by infrared spectroscopyLong the standard for monitoring intubated patients, especially in the operating room and intensive care units, capnography is now a standard tool for assessing ventilation in both intubated and non- intubated patients
109 Ventilation and Capnography Our bodies “blow off” CO2, so during expiration an upstroke in the waveform is seenThis creates a plateau until the end of expiratory phaseIt is at this peak level that the EtCO2 value is measured and resultedDuring inspiration, CO2 is purged from the airway and alveoli, so the waveform drops down to baseline
111 Field Application for Capnography Triage ToolHelp narrow a differential diagnosis of dyspneaAssist in assessing severity of asthma attackTrend CO2 retainers if patient has COPDMonitor for relapses following therapiesSuch as following administration of a bronchodilatorCPRCorrelate blood delivery to the lungs (adequate chest compressions, ventilations)According to American Heart, persistent low CO2 suggests that return of spontaneous circulation is unlikely but an abrupt increase to normal CO2 value is a reasonable indicator of return of spontaneous circulation (ROSC).
112 Field Application for Capnography Endotracheal or other advanced airway placement confirmationWaveform should appear to be SQUARE if tracheal intubation is successfulOngoing assessment of ventilations following insertion of advanced airwayRate AND volume of assisted ventilation
114 OxygenationAdequacy of oxygenation, such as pallor, cyanosis or other physical findings are not as reliable as signs of ventilation (ie: chest-rise and fall, resp. rate)Pulse-oximetry is the quantitative tool that monitors saturation of peripheral O2 (oxygenation/SpO2)This tool has its limitations:Hypoxia follows hypoventilation, which can take30 seconds or more for the pulse-ox to reflectHypovolemia, vasoconstriction, peripheral vascular disease and even nail polish can cause false readings
115 Oxygen Delivery Devices Nasal Cannula – delivers 1-6L, approximately % concentration, of O2Indications for use: treat hypoxia, dyspneaor increased myocardial workContraindications: nasal trauma or blockageConsider placing patient on 10L while intubating!
116 Oxygen Delivery Devices Non-rebreather Mask – delivers 10-15L,approximately 90% concentration, of O2Indications for use: respiratory distress, traumaContraindications: CO2 retainer such as COPD exacerbationBag-valve Mask – delivers15L, 90%+ concentration, of O2Indications for use: respiratory failure, supportfor bradypnea or apnea, positive pressure toopen the airway/alveoli (this is used to admin-ister oxygen and ventilations BOTH)
117 Ventilation vs Oxygenation *** REMEMBER: the provider is the best “monitor” ***If available, combining pulse-ox and capnography are ideal for monitoring oxygenation and ventilation, as providers can detect insufficiencies early and interveneWhile they are helpful tools, Pulse-oximeters and capnometers do not treat the patient, YOU DOThe provider in charge of the airway and ventilating needs be able to focus on this task only so as not to have poor outcome that hyperventilating a patient can cause
120 EMD/BLSCall comes in as an 8 year old shortness of breath from the local elementary schoolEMD: What questions would you ask the caller?EMD: Which units would you dispatch? How many?
121 BLS Arrives on Scene: General Appearance Work of Breathing Circulation Awake, alert, anxiousWork of BreathingDyspneaCirculationHot, dry, red, patchy, swollen areas on skin of extremities and face
122 BLS Scenario A – patent (“tightening”), no stridor noted at this time B – increased effort, audible wheezes without auscultation, SpO2 92%C – flushed, capillary refill is 2 seconds, pulse is strong and fastVitals: B/P 105/65, P 128, R 30, T 99.0S - hives, itchy, throat tightening and dyspneaA – tree nuts, no known drug allergiesM – EpiPen Jr (at home), Albuterol inhalerP – asthma, seasonal and food allergiesL – lunch about a 20 min agoE - ate a cookie offered to him by another student, started to feel throat closing feeling and itchy, hot skin in class right after lunch
123 BLS Scenario Obtain SAMPLE history Initial Medical Care You have already assessed for signs of respiratory distress vs failureReassure patient, place in position of comfortShould this patient receive oxygen? What would you use to deliver this? Should you assist ventilations?Oxygen administration is appropriate, O2 saturations will determine NC vs non-rebreather. A nebulized bronchodilator would be recommended if ALS became available due to the audible wheezing.If the patient started to have more throat closing with stridorous sounds, accessory muscle use and dropping SpO2, he may needed assisted ventilations. Consider BVM or if ALS arrives, these are indications for CPAP. (Follow your system-specific procedures)
124 BLS ScenarioShould you give this patient an auto-injection of Epinephrine (EpiPen)?Where is the site of injection?What if the school nurse says she cannot find his prescribed EpiPen and hands you an adult EpiPen because its all she could find?With symptoms such as dyspnea, wheezing, throat tightness and diffuse hives, it is recommended that the patient use EpiPen.Injection site is anterolateral aspect of the quad muscle (thigh).If an adult EpiPen is the only form of Epinephrine available, this is not weight-based dosing for a pediatric patient, therefore do not administer the injection and contact your medical control for direction.
127 BLS Skill Review Indications for use of EpiPen EpiPen® (epinephrine) 0.3 mg and EpiPen Jr® (epinephrine) mg Auto-Injectors are indicated in the emergency treatment of type 1 allergic reactions, including anaphylaxis, to allergens, idiopathic and exercise-induced anaphylaxis, and in patients with a history or increased risk of anaphylactic reactions. Selection of the appropriate dosage strength is determined according to body weight.Important Safety InformationEpiPen Auto-Injectors should only be injected into the anterolateral aspect of the thigh. DO NOT INJECT INTO BUTTOCK, OR INTRAVENOUSLY.
130 BLS/ALS ScenarioYour medic unit is dispatched for 78 year old female shortness of breathYou arrive on scene where a daughter directs you to the bedroom to find the female patient sitting in high-fowler’s position with several pillows propped behind herAppearance: awake and alert with a GCS of 15Increased work of breathing notedSkin is paleBLS can start IMC, but this patient warrants ALS protocols.

132 ALS Are we thinking pulmonary edema d/t heart failure? Goal is to reduce the preload and afterload on the heartadministration of nitroglycerinIf available, place the patient on continuous waveform capnographyCPAP should be considered sooner rather than laterReduces work of breathingHelps reduce preload on the heartDo we use a diuretic? NO!!!It is no longer believed that patients experiencing CHF are in volume overload, rather they have inappropriate volume distribution. This is one of the reasons Lasix has been removed from the new SOP for pulmonary edema.
