AbstractManual inflation of the lungs by the 'bag squeezing method' (bagging) is commonly used by physiotherapists in the management of intubated patients. A wide variety of 'bagging' circuits are available and the peak expiratory flow rate that can be achieved is influenced by the circuit components. A high expiratory flow rate is desirable as it is believed to be one of the factors that determines the effectiveness of secretion mobilisation during a simulated cough in intubated patients. This study was designed to compare the expiratory flow rates resulting from the elastic recoil of a test-lung using the Mapleson-C breathing system and the Laerdal self-inflating resuscitator. Our data demonstrated that for any given pressure gradient the measured peak expiratory flow was higher with the Laerdal self-inflating resuscitator (p < 0.001). Further studies are required to assess the influence of circuit-type pulmonary secretion mobilisation in clinical practice.
