3 Review: Carbon Monoxide Poisoning For Emergency Responders Section 1Review: Carbon Monoxide Poisoning For Emergency Responders
4 IntroductionCarbon monoxide is the leading cause of poisoning in the United States for the last 100 years and is a common hazard to First Responders.Until recently, the only way to reliably diagnose carbon monoxide poisoning was to draw blood and check the carbon monoxide levels in a lab. With the introduction of the Masimo Rad-57, testing for carbon monoxide can now be done quickly and easily, allowing for prompt screening and treatment.This training program covers carbon monoxide poisoning recognition and treatment and the use of the Masimo Rad-57 Pulse CO-OximeterTM. As always, seek direction and approval from your physician or Medical Director prior to using this training program or a Masimo Rad-57.
5 DefinitionCarbon monoxide is a colorless, odorless, tasteless, toxic gas that, when inhaled, can cause serious physical problems and even death.Carbon monoxide is often referred to as “CO”, which is its chemical symbol. Even at low levels, carbon monoxide may cause long- term cardiovascular and neurological disorders.Carbon monoxide can be a serious and sometimes deadly threat to Firefighters and EMS personnel. Firefighters have regular contact with carbon monoxide at fire and rescue scenes, increasing their health risks.
6 Common SourcesIncomplete combustion of any carbon-based material will produce carbon monoxide. Closed or confined spaces are particularly hazardous. Common sources are:Automobiles, trucks, busesBoats, campersGas heaters, furnaces, and hot water heatersGas-powered generatorsSmall gasoline enginesPortable / space heatersBarbecues / fireplacesCigarette smokeLanternsMethylene chloride (paint stripper)Liver converts to COStructure / wildland fires
7 PhysiologyCarbon monoxide is inhaled and passes from the lungs to the blood where it binds with hemoglobinProduces carboxyhemoglobinAffinity to hemoglobin is greater than 200 X that of oxygenReduces oxygen carrying capacity of bloodAlters release of remaining oxygen to cellsActs as an intracellular toxinPoisons tissues and cellsBinds with myoglobin in muscleInterferes with heart and skeletal muscleImmediate threat to lifeOxygen starvationCardiac arrhythmiasAlters judgment, reasoningLong-term health effectsCentral nervous system damageCardiovascular damage

9 Treatment Considerations Scene safety, protect yourself:Consider SCBARemove patient away from the poison!ABC’s (airway, breathing and circulation)Check CO level with Pulse CO-OximeterHigh levels treated with 100% oxygen:Decrease half-life of CO in bloodIncrease delivered oxygen in bloodSupport ventilations as neededTransport to closest, most appropriate facilityConsider hyperbaric treatment center:Adults >25%, Pedi & Pregnant female >15%Neurologic compromiseMonitor vital signs and SpCO®Always follow local EMS protocols
10 Suggested Triage Algorithm Measure SpCOSpCO 0-3%SpCO >3%No further medical evaluation of SpCO neededLoss of consciousness or neurological impairment or SpCO >25% ?YesNoTransport on 100% oxygen for ED evaluation. Consider transport to hospital with hyperbaric chamberSpCO >12SpCO <12Transport on 100% oxygen for ED evaluationSymptoms of CO exposure?No further evaluation of SpCO needed. Determine source of CO if nonsmokerHampson NB, Weaver LK JEMS 2006
11 Half-LifeHalf-life: The amount of time required to reduce the blood level of CO by 50%. These are estimates for patients that otherwise are healthy. Age and health will impact the half-life of CO.Breathing Room Air: Carbon Monoxide half-life in blood is ~ 240 minutesHigh-flow oxygen (“100%”) via non- rebreather mask: Decreases CO Half- life in blood to minutesHyperbaric Oxygen Treatment (HBOT) at 2.5 to 3 Atmospheres: Decreases CO half-life in blood to minutes
12 Understanding PPM & SpCO PPM or “Parts Per Million” is the atmospheric concentration of the gasPPM is common fireground safety measurement, often misleading as CO forms in pocketsSpCO - noninvasive measurement of CO in the bloodSpCO as measured by RAD-57 is a function of PPM CO and total time of exposure of the poisonAge, health and respiratory rate may be a factorEven low PPM levels can lead to high SpCO if exposure is long enough, common in overhaulEven an exposure of 50 PPM for 60 minutes requires assessment and possible medical treatment with oxygen
13 Firefighter RiskCO levels may be highest during the post-fire or “overhaul” phase, search & rescue operations and wildland firefightingPeriods that self-contained breathing apparatus (SCBA) are not worn or not functioning properlyCO poisoning is often unrecognized due to the presence of exhaustion, heat stress, illness or injuriesStudies have shown low levels of untreated CO lead to central nervous system and cardiovascular diseaseModerate to high levels are immediate threats to health and safety, and cause cardiovascular injury

26 RAD-57 Operation / Improving Accuracy The Rad-57 is designed with an accuracy of +/- 3 digits with a range of 1% - 40% for one standard deviation (67% of patients)Example: A reading of 10% could have a range from 7% - 13%Measurements may vary from reading to reading, even on the same patient, within the accuracy specificationProper probe placement may improve accuracyIf an abnormal level of CO is detected, always confirm by measuring other fingers and averageFlashing lights, strobes or high ambient light may interfere, use a Masimo Light Shield or other means of shielding
27 RAD-57 Operation / Contraindications Small physiological changes and acceptable levels of arterial perfusion along with correct sensor placement will provide a stable CO reading. Inaccurate measurements may be caused by:Incorrect sensor placementElevated levels of methemoglobinIntravascular dyes such as indocyanine green or methylene blueAbnormal hemoglobin levelsLow arterial perfusionLow arterial oxygen saturation levelsElevated Total Bilirubin levelsMotion artifact
