Abstract

Conventional mechanical ventilation (CMV) can readily produce haemodynamic changes in both the pulmonary and systemic circulations, and obvious interaction can be observed between intratracheal and intra-alveolar pressures and the circulatory state of the patient. High-frequency ventilation has often been claimed to result in gas exchange of equal efficiency to, if not better than, that which can be achieved with CMV. At the same time, peak and mean intratracheal pressures are lower than those observed during CMV. The main factor in determining the degree of interaction between circulation and mechanical ventilation is the level to which the mean tracheal pressure rises. Numerous studies have demonstrated that increasing positive end-expiratory pressure (PEEP) may have deleterious effects on circulatory performance. Few studies have been performed examining the moment of insufflation in relation to the phase of the heart cycle and the consequences that this may have for the pulmonary and systemic circulations.
