Noninvasive ventilation

Background

• CPAP = PEEP = EPAP
• BiPAP = PEEP + (pressure support = IPAP)

Indications

1. CHF
2. COPD
3. Asthma
4. OSA
5. Pulmonary edema
6. Pneumonia

Settings

1. Failure of oxygenation
   1. Pulmonary Edema, PNA
   2. Start PEEP 5 (up to 15)
      1. Recruits alveoli
      2. Improves V/Q mismatch
      3. Decreases preload/afterload
2. Failure of ventilation
   1. Asthma, COPD
      1. When tire out unable to move air
   2. Need inspiratory pressure support
   3. Start pressure support 5 (up to 15)
   4. Consider PEEP 2-3 to overcome the mask
