Web13 de jun. de 2016 · Under normal circumstances, inspiration is accomplished by causing alveolar pressure to fall below atmospheric pressure. When the mechanics of breathing are being discussed, atmospheric pressure is conventionally referred to as 0 cm H 2 O, so lowering alveolar pressure below atmospheric pressure is known as negative … WebNegative intrathoracic pressure is also reflected in the perivascular space, decreasing the perivascular pressure. This increases extravascular lung water by favoring fluid transudation across pulmonary microvascular bed and by diminishing lymph outflow from the lungs. 109 Sleep apnea may therefore contribute to excess lung water and pulmonary …
