7 Chronic Obstructive Pulmonary Disease COPD conditions:Are progressive and irreversibleHave diminished inspiratory and expiratory capacity of the lungsObstruct the flow of air to or from the patient’s bronchiolesIncludes:Emphysema: Loss of lung elasticity and hyperinflation of lung tissue. Causes destruction of the alveoli leading to decreased surface area for gas exchange, carbon dioxide retention, and respiratory acidosis.Chronic Bronchitis: Bronchial inflammation and excessive mucous secretion result in airway obstruction. Caused by smoking or chronic lung infectionsAsthma: A chronic inflammatory disorder of the airways. Intermittent periods of bronchospasm resulting in wheezing and difficulty breathing. Triggered by stimuli.Bronchiectasis: Chronic dilation of bronchi that eventually destroys bronchial elastic and muscular elements. Muscle tone is gradually lost after one or more pulmonary infections.

10 Medical Management/Medications Maintenance therapy- to be taken on a regular basis to prevent and minimize symptoms.examples: Serevent, Flovent, Singular, TheophyllineAcute (rescue) therapy- quickly relieves symptoms of an asthma attack.examples: Albuterol, Corticosteroids, EpinephrineBronchodilators: assist in opening the airwaysAlbuterol (Proventil, Ventolin), Ipratropium (Atrovent), TheophyllineAnti-inflammatory: used to decrease inflammationCorticosteroids: Flovent and PrednisoneLeukotriene antagonists: SingulairMast cell stabilizers: IntalMonoclonal antibodies: XolairCombination Agents: Bronchodilator and Anti-InflammatoryCombivent and AdvairRecommended yearly flu shot andpneumococcal vaccine every 5 years
11 Pneumonia : inflammation of bronchioles and alveolar sacs Caused by infection, over sedation, inadequate ventilation, or aspirationInfection could be caused by bacteria, viruses, mycoplasma, fungi, or chemicalsCurrently about 50% of cases are caused by bacteria and 50% by virusesSigns and symptoms vary with the type of pneumoniaStreptococcal, pneumococcal: sudden onset, chest pain, fever, headache, cough, rust colored sputum, crackles, possible plural friction rub, hypoxemia, cyanosis, visible on chest x-ray, Vaccine AvailableStaphylococcal: same as streptococcal with copious, salmon colored sputumKlebsiella: many same as streptococcal with gradual onset, more bronchial pneumonia, and if treatment is delayed beyond second day of onset patient becomes critically ill and mortality highHaemophilus: commonly follows upper respiratory infection, low grade fever, croupy cough, malaise, arthralgias, yellow or green sputumMycoplasmal: gradual onset, headache, fever, malaise, chills, severe nonproductive cough, decreased breath sounds and crackles, x-ray will be clear and white blood count normal.Viral: generally mild, cold symptoms, headache, anorexia, myalgia, irritating cough, mucopurulent or bloody sputum, bronchopneumonic type infiltration on chest x-ray, white blood cell count usually high with rise in antibody titers
12 Pneumonia Diagnostics/Lab Sputum for culture and sensitivity Collected before eating and before start of antibioticsChest radiograph reveals changes in densityWhite blood countNormal or low in viral or mycoplasmalElevated in bacterial, Leukocytosis with a shift to the leftABG’s identify altered gas exchangePulse oximetry monitors oxygen saturationMedical InterventionsAntibiotics: penicillin, erythromycin, cephalosporin, and tetracyclines depending on causative organismAnalgesics – Tylenol, IBU, Vicodin, PercocetAntipyretics – Tylenol, IBUExpectorants – Guiafenesin (Robitussin)Mucolytics - MucinexBronchodilator – Albuterol, Atrovent, SereventHumidification or nebulizersOxygen if below 90%Pneumococcal Vaccine (most common bacteria pneumonia)Good for lifetime when healthyRepeat every 5 years if immunosuppressed or at risk for development of fatal infectionRecommended chronic illnesses, recovering from serious illness, over age 65, or in a long term care facility
13 Pneumonia Good Hand Hygiene! Nursing Diagnosis Nursing Interventions Ineffective breathing pattern r/t inflammatory process and pleuritic painImpaired gas exchange r/t alveolar capillary membrane changes secondary to inflammationNursing InterventionsHelp pt conserve energy with periods of restHigh or Semi-Fowler’s positionProvide hydration at least 3L per day unless contraindicated (Heart Failure)Monitor temperature and VSDeep breathing and cough exercisesIncentive spirometryPossible oxygen therapyAuscultate for crackles, wheezes, and pleural friction rubAssess ventilationBreathing rate, rhythm, depth, and chest expansionAssess for respiratory distressDyspnea, sob, nasal flaring, pursed lip breathing, prolonged expiratory phase,and use of accessory musclesS/S Hypoxia: restlessness, irritability, and disorientationGood Hand Hygiene!
14 Lung Cancer Abnormal cell growth/overgrowth: Two Classifications: -Oncogenes/Tumor Suppressors malfunctionTwo Classifications:Small-cell lung cancer10-15%- directly related to smokingNon-small cell lung cancer85-90%- Squamous cell carcinoma- Adrenocaricoma- Large cell carcinomaRisk FactorsGeneticSmokingOccupational exposures
15 Signs and Symptoms Varies depending on type/extent of disease HoarsenessRecurring infectionsNeuro changesJaundiceLumpsWeaknessDysphagiaWheezingCoughWeight lossDyspneaChest painHemoptysisBone painClubbingFever
18 Nursing Diagnoses/Interventions Ineffective airway clearance r/t lung surgery.-Facilitate optimal breathing by placing patient in a sitting position.-Assist with position changes frequently.-Encourage early ambulation to mobilize secretions.-Encourage I.S.Fear, related to cancer, treatment, and prognosis.-Monitor changes in communication patterns-Listen/accept without personalizing reaction-encourage to identify problem, redefine situation, obtain needed information, generate alternatives, and focus on solutions.
19 Laryngeal Cancer Squamous cell carcinoma - Slow growing if only involving true vocal cords- Faster elsewhere in larynx- Men 3x more likely to be affected than women.- Most occur after age 60.- Impacts breathing, speaking, and eating.Risk FactorsChronic exposure to harmful chemicalsTobacco/alcoholChronic laryngitisVocal abuseFamily history
20 Signs and Symptoms Diagnostics/Labs Progressive/persistent hoarseness (2+ weeks)Referred pain to the earDyspneaDysphagiaHemoptysisMouth sores/lesions that fail to healLump in throat/mouth/neckUnilateral ear painWeight loss/anorexiaEnlarged cervical lymph nodesDiagnostics/LabsX-RayCT ScanMRILaryngoscopyBone scanPET scanBiopsy and microscopic study
21 Laryngeal Cancer Treatment Treatment is determined by the extent of tumor growth*Radiation- if limited to true cords* Surgery- tumor affixed to cord(s)* Partial Laryngectomy- temporary tracheostomy*Total Laryngectomy- permanent tracheostomy-Tracheoesophageal fistulas, esophageal speech,electorlarynxes* Radical neck dissection- in conjunction with total laryngectomy- shoulder droop
22 Nursing diagnoses/Interventions Ineffective airway clearance, r/t secretions/obstruction- Suction as needed- Tracheostomy care- Small, frequent feedings/liquid or pureed food- Teach stoma protection- Turn, CDB q 2-4 hours- Maintain HOB 30 degrees or higher- Respiratory rate q 1-2 hours- Auscultate lungs and monitor O2 q 4 hoursImpaired communication, verbal, r/t removal of larynx- Provide implements for communication- Keep call light in reach at all times- Ask yes/no questions when possible- Refer to local support groups

There are many types of masks that can be trialed, desensitization programs, and adjustments that can be made to the machine.***
