Effects of varying inspiratory flow waveform and time in intermittent positive pressure ventilation. III: Blockade of the autonomic nervous system. 1977

A B Baker, and R W Cowie, and J E Colliss

The autonomic nervous system was blocked in dogs which were exposed to independent alterations in inspiratory flow waveform and time whilst being ventilated artificially at a constant volume and frequency. There were statistically significant differences in cardiac output between the control and blocked states, but these differences were not of marked physiological significance. Alteration in inspiratory waveform or time in the blocked animals did not alter cardiac output significantly.

D011175	Positive-Pressure Respiration	A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange.
