The major mechanisms that drive pulmonary ventilation are atmospheric pressure ( P atm) the air pressure within the alveoli, called intra-alveolar pressure ( P alv) and the pressure within the pleural cavity, called intrapleural pressure ( P ip). The intra-alveolar and intrapleural pressures are dependent on certain physical features of the lung. However, the ability to breathe-to have air enter the lungs during inspiration and air leave the lungs during expiration-is dependent on the air pressure of the atmosphere and the air pressure within the lungs.
