When to use cpap and bipap ? what is the difference between them ?

Bipap better: Bipap blows two at two pressures--a higher one to facilitate inhaling, then drops lower on exhale, so it is easier. CPAP blows continuously at one pressure for operational simplicity.

CPAP vs BIPAP: Hi, both are providing positive pressure and keep the airways open at all time, while CPAP provides a constant flow of air and keeps the airway pressure positive but BIPAP creates 2 level of positive pressure which machine can alternate between these pressure and usually use as an alternative of non-invasive ventilation in MICU in COPD patient with respiratory failure and also in sleep apnea with

Pressure Difference: CPAP, or Continuous Positive Airway Pressure, is a setting in which a fixed pressure is delivered to your upper airway by a nose or face mask. It is constant and does not fluctuate. BiPAP, on the other hand, has two pressures: one when you breathe in and the other when you breathe out. CPAP is typically used for sleep apnea. So can BiPAP, but it can also be used to help breathing in CHF.
