[Study of pressure and FeCO2 during ventilation by injection (preliminary note)].
This study, carried out in nine patients, attempted to judge the efficacy and possible inocuity of ventilation by injection (jet ventilation), firstly on capnography and. secondly, on recordings of intra-tracheal pressure. The frequency of six jets per minute, is that which, under the conditions of the trial, ensures the best removal of CO2 and the maintenance of stable CO2 levels in the trachea. Although pressures recorded in the airways varied between 15 and 40 torrs, the finding of very high peaks of pressure in certain cases, makes the authors somewhat reserved concerning the security of the method when the free reflux of gas is liable to be inhibited.
