Positive end-expiratory pressure causes increase in which respiratory parameter ?: (A) Lung compliance, (B) FRC, (C) Tidal volume, (D) All of the above
Answer is D. 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 (PEEP)PEEP 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 ventilation/pe{usioa abnormalities - Improved oxygenation.
