Figure 4

Haemodynamics during continuous positive-pressure ventilation (CPPV) and continuous external negative-pressure ventilation (CENPV). Measurements were taken at time 0 (5 minutes after the recruitment manoeuvre) immediately after starting the 2-hour ventilatory period of CPPV or CENPV. The changes in intravascular pressure effects were more permanent in contrast to the more transient effects on intrathoracic blood volume and cardiac index. *P < 0.05 compared to corresponding values at 1 or 2 hours during CPPV.
