The single most important treatment: Supplementary
O2 for O2 sat > 90. Works immediately.
Sitting up often helps breathing
Nebulizer treatment for asthma, COPD;
Bag if necessary
Decompress tension pneumothorax
Circulation
Therapy onset time
Oxygen: 1min
 Albuterol: 15 to 30 min
 Atrovent: 15 to 30 min
 Lasix: 30 min to 1 hr
 Steroids: 4 to 6 hrs

COPD
Airflow obstruction due to chronic
bronchitis or emphysema
 Rare before 40
 90% smokers
 Mortality for average COPD exacerbation
hospitalization: 5 to 14%
 Decompensation due to URI,
bronchospasm, noncompliance, others

Signs/Symptoms

Dyspnea and orthopnea
Progressive hypoxemia
Tachypnea, tachycardia
Cyanosis
Increased BP
Apprehension
Tripod position, pursed lip exhalation,
diaphoresis
Eventually hypercapnia, confusion, obtundation
COPD Exacerbation Management
Airway
 Breathing

O2 to sat > 90%
 Nebulized albuterol q20min
 Nebulized atrovent 1 dose with albuterol
 Solumedrol typical dose 125mgIV
 (Methylxanthines, antibiotics)
 Assisted ventilation if needed
