1, psv is a mode of autonomic respiratory support, available only in patients with autonomic respiration, those without autonomic respiration or those with unstable autonomic respiration can not be used.
2, peep is a parameter, that is, positive end-expiratory pressure, for mechanical ventilators in the inspiratory phase to generate positive pressure, gas into the lungs, in the end of expiration airway opening, airway pressure remains higher than atmospheric pressure to prevent alveolar atrophy and collapse. It plays an important role in the treatment of respiratory distress syndrome ARDS, noncardiogenic pulmonary edema, and pulmonary hemorrhage.
3. In modern clinical medicine, the ventilator, as an effective means that can artificially replace the function of autonomous ventilation, has been commonly used in respiratory failure due to various causes, anesthesia respiratory management during major surgery, respiratory supportive therapy and emergency resuscitation, and occupies a very important position in the field of modern medicine. The ventilator is a medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the patient's life.
