<prompt> Positive end-expiratory pressure causes increase in which respiratory parameter ?Lung complianceFRCTidal volumeAll of the above  <response>: Ans. is d i.e., All of the abovePositive airway pressure therapy means providing positive pressure during breathing. It may be :-1. Positive end-expiratory pressure PEEPPEEP is the positive pressure is applied at the end of respiration during mechanical ventilation.2. Pulmonary effects of PEEP and CPAPPositive pressure in PEEP CPAP results in : -Re-expansion recruitment and stabilization of paially collapsed lung which causes : -Increased FRC, tidal volume lung compliance. Connection of ventilationpeusioa abnormalities - Improved oxygenation.
