Description
Technical Field
The invention relates to the technical field of thoracic cavity pressure testers, in particular to a thoracic cavity pressure tester.
Background
The forces acting on the pleural cavity are of two kinds, acting on the pleural cavity through the pleural visceral layer: firstly, the pulmonary pressure makes the alveolus dilate; one is the elastic recoil of the lung, which causes the alveoli to shrink. Thus, the pressure within the pleural cavity is actually the algebraic sum of these two opposing forces, namely: the intrapleural pressure is equal to the atmospheric pressure at the end of inspiration and expiration, and the intrapleural pressure is equal to the atmospheric pressure, so if the intrapleural pressure is equal to the atmospheric pressure and the pulmonary elastic retractive force is based on the standard of 0 bit of 1 atmospheric pressure, then: lung elastic retractive force when the lung elastic retractive force is 0.665kPa (5mmHg), the lung elastic retractive force is-0.665 kPa (-5mmHg), and the actual pressure value is 101.08kPa-0.665kPa (l00.415kpa) (760mmHg-5 mmHg) (755 mmHg). It can be seen that the negative pleural cavity pressure is caused by the elastic recoil of the lungs. When inhaling, the lung expands, the elastic retractive force of the lung increases, and the negative pressure in the pleural cavity is more negative. During expiration, the lung contracts, the lung elastic retractive force is also reduced, and the pleural cavity negative pressure is also reduced. No matter inspiration or expiration, the internal pressure of the pleural cavity is lower than the atmospheric pressure and is negative pressure, the negative pressure is increased during inspiration, and the negative pressure is reduced during expiration. The negative pressure of the pleural cavity can maintain the expansion state of the lung and ensure the normal ventilation of the lung; the negative pressure of the pleural cavity can reduce the central venous pressure, and is favorable for the backflow of venous blood and lymph fluid.
