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. WebOne way to improve outcomes in states of low blood flow is to enhance negative pressure in the chest by using intrathoracic pressure regulation (IPR) therapy. This treatment …
