Intrapleural Pressure Changes During Respiration - Chegg

WebDuring normal spontaneous breathing, intrathoracic pressure is negative throughout the ventilatory cycle. Intrapleural pressure varies from about −5 cm H 2 O during exhalation to −8 cm H 2 O during inhalation. Alveolar pressure fluctuates from +1 cm H 2 O during exhalation to −1 cm H 2 O during inhalation. WebIntrapleural pressure is commonly found between the visceral and the parietal layers. This pressure is exerted on the complete thoracic cavity. Normal Values The atmospheric pressure is interrelated to respiratory pressure.
