function of the ventilator.
The company has ventilator products.
In modern clinical medicine, ventilator is an effective means to artificially replace the function of spontaneous ventilation.
Ventilator Hold breath at the end of inspiration
After the end of inhalation and before the beginning of exhalation, the ventilator does not supply air, and the exhalation valve continues to close for a period of time to maintain the pressure in the lungs at a certain level.
Clinical application: (1) Prolonged inspiratory time, which is beneficial to gas distribution. (2) Facilitate the dispersion of gas (3) Facilitate the distribution and diffusion of inhaled drugs in the lungs
Ventilators can increase the burden on the heart.
Ventilator Positive end-expiratory pressure ventilation
At the end of expiration, the airway pressure does not drop to 0, and still maintains a certain positive pressure level.
Clinical application: Ventilator is suitable for hypoxemia caused by intrapulmonary shunt, such as ARDS
The mechanism of PEEP to correct ARDS (1) Reduce alveolar collapse, reduce intrapulmonary shunt, and correct hypoxemia caused by intrapulmonary shunt (2) Reduce alveolar collapse and increase FRC, which is beneficial to alveolar-capillary two Adequate exchange of side gas. (3) The increase of alveolar pressure increases the alveolar-arterial oxygen partial pressure, which is conducive to the diffusion of oxygen to the capillaries. (4) The increased inflation of the alveoli can increase the compliance of the lungs and reduce the work of breathing.
The main side effects of ventilator PEEP (1) the effect on hemodynamics (2) the barotrauma to the lung tissue (3) the ability to compress the pulmonary capillaries. Decreases pulmonary blood flow and may increase ineffective ventilation. (4) It can reduce alveolar surfactant.
