Intrapleural pressure is different from intrathoracic pressure. The thoracic cavity is the space that includes the pleura, lungs, and heart, while the pleural space is only the space between the parietal pleura and visceral pleura surrounding lungs. Intrapleural pressure depends on the ventilation phase, atmospheric pressure, and the volume of ...
With inhalation, the intrapleural pressure (the pressure within the pleural cavity) of the lungs decreases. Relaxing the diaphragm during expiration allows the lungs to recoil and regain the intrapleural pressure experienced previously at rest. Elastic recoil is inversely related to lung compliance.
If 'transpulmonary pressure' = 0 (alveolar pressure = intrapleural pressure), such as when the lungs are removed from the chest cavity or air enters the intrapleural space (a pneumothorax), the lungs collapse as a result of their inherent elastic recoil. Under physiological conditions the transpulmonary pressure is always positive; intrapleural ...
The pleural cavity, or pleural space (or sometimes intrapleural space), is the potential space between the pleurae of the pleural sac that surrounds each lung.A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes, and also to create a pressure gradient.
Towards the base of the lungs, the fluid volume in the pleural cavity increases due to gravity, resulting in greater intrapleural pressure. As a result, alveoli expand less and become more compliant at the base, improving ventilation. Perfusion also increases as gravity pulls down the blood towards the base.
Dynamic compression of the airways results when intrapleural pressure equals or exceeds alveolar pressure, which causes dynamic collapsing of the lung airways. It is termed dynamic given the transpulmonary pressure (alveolar pressure − intrapleural pressure) varies based on factors including lung volume, compliance, resistance, existing pathologies, etc. [1]
External suction (previously referred to as active suction) is used to create a sub-atmospheric pressure at the tip of a catheter.As the atmospheric pressure is lower compared to the intrapleural pressure, the lack of external suction (which was previously referred to as passive suction) is used to drain air and fluids. [1]
Since the heart resides in the thoracic cavity between the lungs, the partial pressure of inhaling and exhaling greatly influence the pressure on the vena cava and the filling of the right atrium. During inspiration, intrapleural pressure decreases by up to 4 mm Hg, which distends the right atrium, allowing for faster filling from the vena cava ...
