Description
Technical Field
The invention relates to the technical field of thoracic pressure testers, in particular to a thoracic pressure tester.
Background
There are two types of forces acting on the pleural cavity, acting on the pleural cavity through the pleural layer: firstly, the pulmonary internal pressure expands alveoli; first, the elastic recoil of the lung reduces the alveoli. Thus, the pressure within the pleural cavity is actually the algebraic sum of these two opposing forces, namely: intrapleural pressure = intrapulmonary pressure-pulmonary elastic recoil force at the end of inspiration and end of expiration, intrapulmonary pressure is equal to atmospheric pressure, so intrapleural pressure = atmospheric pressure-pulmonary elastic recoil force if 0-bit standard with 1 atmosphere: intra-pleural pressure= -pulmonary elastic recoil force if the pulmonary elastic recoil force is 0.665kPa (5 mmHg), the intra-pleural pressure is-0.665 kPa (-5 mmHg), and the actual pressure value is 101.08kPa-0.665 kpa=l00.415 kPa (760 mmHg-5 mmhg=755 mmHg). It can be seen that the negative pleural cavity pressure is caused by the elastic recoil of the lungs. During inspiration, the lung expands, the elastic retractive force of the lung increases, and the negative pressure of the pleural cavity is also more negative. During exhalation, the lung is contracted, the elastic retractive force of the lung is also reduced, and the negative pressure of the pleural cavity is also reduced. The internal pressure of the pleural cavity is lower than the atmospheric pressure no matter inhaling or exhaling, the negative pressure is increased during inhaling, and the negative pressure is reduced during exhaling. The negative pressure of the pleural cavity can maintain the expansion state of the lung, and ensure that the lung ventilation is normally carried out; the negative pressure of the pleural cavity can reduce the central venous pressure, which is favorable for the reflux of venous blood and lymph fluid.
