NBRC: NPPV

1. increase oxygenation

2. support oxygenation at lower fiO2

1. Leak

2. Insufficient flow

1. Obstruction

2. With excess flow, a continuous venting of the pop-off valve will occur

1. to avoid intubation in pts with: COPD, CHF, Pulmonary Edema

2. Facilitate long term ventilation at home

• 3. Provide Periodic support for pts with:
• a: Neuromuscular disease
• b: Restrictive chest wall disease
• c: Central/Obstructive Sleep Apnea

1. Poor fitting mask

2. Irritation or ulceration from mask

3. Leaks around mask or in tubing

4. Gastric distention from high pressures

5. Contraindicated for pts with dysphagia

This is the same as CPAP and can be used to improve oxygenation or to prevent airway closure in OSA

This is set higher than EPAP, + pressure applied during inspiration.

Used to maintain patent airway in OSA

Can also be used with pt who req. inspiratory assist to maintain adequate ventilation following extubation to avoid intubation and cmv

1. Allows pt to breathe at spontaneous rate with combined timed breaths as in SIMV

2. Bipap

3. The timed breaths are controlled by selecting a rate and an i time percent

1. provieds only time controlled breaths at selected inspiratory and expiratory pressures

2. the pt can't trigger additional mandatory breaths. I timepercent must be selected and monitored to determine the delivered VT

5-10 cwp

6-8 cwp and increase as necessary
