Positive end-expiratory pressure improves elastic working pressure in anesthetized children

tailieu.vn

Positive end-expiratory pressure improves elastic working pressure in anesthetized children. Background: Positive end-expiratory pressure (PEEP) has been demonstrated to decrease ventilator-induced lung injury in patients under mechanical ventilation (MV) for acute respiratory failure. Recently, some studies have proposed some beneficial effects of PEEP in ventilated patients without lung injury. The influence of PEEP on respiratory mechanics in children is not well known.

Positive-pressure mechanical ventilation is the mainstay of respiratory supportive therapy in patients with acute respiratory distress syndrome (ARDS) [1, 2]. Application of positive end-expiratory pressure (PEEP) is one of the. Another proposed approach is to increase the time during which positive pressure is applied at the airway opening, through inverse-ratio ventilation (IRV) [7 – 9].

Giáo trình PEEP và Auto-PEEP

Khi áp suất phế nang cao hơn áp suất tại miệng vào cuối kỳ thở ra thì người ta gọi đây là áp suất dương cuối kỳ thở ra (PEEP : Positive end-expiratory pressure). Tại sao lại đề cập đến áp suất tại miệng và áp suất khí quyển (atmospheric pressure)?. PEEP được định nghĩa là sự chênh lệch (dương) giữa áp suất phế nang và áp suất tại miệng vào cuối kỳ thở ra.. Ở người không bị đặt nội khí quản thì áp suất tại miệng luôn bằng áp suất khí quyển..
