EditorWe read with interest the recent article on high frequency oscillation in adolescents by Moganasundram and colleagues.1
The article raises a number of issues regarding the initiation and use of high frequency oscillatory ventilation (HFOV) not just in adolescents but also in adults.
In our unit we have used HFOV for over 3 yr on more than 70 patients. Through experience, we have found that recruiting in a stepwise fashion whilst connected to the oscillator has resulted in better haemodynamic stability and oxygenation. We use the Sensormedics 3100B (Yorba Linda, CA). All patients are connected with a closed suction system (Vygon, Cirencester, UK) in place, to prevent derecruitment with an FIO2 of 1.0 and an amplitude (
P) of 0, on a bias flow of 40 litre min1. Mean airway pressure is
