It is obvious that reduced total Ventilation will decrease alveolar Ventilation and decrease the oxygen supply to the pulmonary capillary blood; at the same time the elimination of carbon dioxide is impeded. This cause of impaired gas exchange will not be dealt with more in this

Drugs and Pulmonary Perfusionanges in pressure may reflect quite profound changes in vascular properties. Principal among these properties is vascular tone, which is a functional concept representing the net State of the vasculature after all of the forces, both active and passive, have interacted.

Influence of Artificial Ventilation and PEEP on Pulmonary Gas Exchange and Oxygen Uptakew modalities of artificial Ventilation have been introduced over the last years. However, simple intermittent positive pressure Ventilation (IPPV) with positive endexpiratory pressure (PEEP) is still the most widely used technique in patients with seriously impaired pulmonary gas exchange. The main
