When a patient on BPAP breathes in, the ventilator will provide constant pressure during the inspiration. When the patient then breathes out, the ventilator will provide a different, lower pressure during expiration.
Ventilator settings for BPAP
The ventilator settings for BPAP are as follows:
- Inspiratory positive airway pressure (IPAP), measured in cmH2O
- Expiratory positive airway pressure (EPAP), measured in cmH2O
- The fraction of inhaled oxygen (FIO2), set between 21% and 100%
Common clinical use for BPAP
The main clinical use for BPAP is in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).
