1. Hypoxic pulmonary vasoconstriction and nitric oxide
Sammanfattning : Hypoxia causes pulmonary vasoconstriction (HPV), improving oxygenation by redistribution of the pulmonary blood flow to better oxygenated lung regions. HPV is intrinsic to the pulmonary vascular smooth muscle cell, but can be modulated by several vasoactive substances, as for example endothelium derived nitric oxide (NO) and endothelin-1 (ET-1).

2. Endothelin in the pulmonary circulation with special reference to hypoxic pulmonary vasoconstriction
Sammanfattning : A number of substances originating from the pulmonary endothelium have recently been found to be involved in the regulation of pulmonary vascular tone. Accumulating evidence suggests that endothelial dysfunction contributes to pulmonary hypertension, an important clinical problem often associated with hypoxemia. LÄS MER

5. Benefits of Spontaneous Breathing : Compared with Mechanical Ventilation
Sammanfattning : When spontaneous breathing (SB) is allowed during mechanical ventilation (MV), atelectatic lung areas are recruited and oxygenation improves thereby. Whether unsupported SB at its natural pattern (without PEEP and at low pressure/small tidal volume) equally recruits and improves oxygenation, and if so by which mechanism, has not been studied.
