Pressure limitation has high pressure limitation and high pressure alarm. They are the high pressure setting value in volume ventilation mode, Pmax, which is the setting of the inspiratory high pressure. Then there is the ventilator has Phigh value, which is the high pressure limit during the whole respiratory process, and this value is usually higher than the former. The difference between them is that Pmax has volume compensation and Phigh does not.

In modern clinical medicine, the ventilator as an effective means of artificially replacing the function of voluntary ventilation, has been commonly used in respiratory failure due to various causes, anesthesia and respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupies a It 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.
In the acquisition of ventilators should follow the following principles:
(1) understanding of the development and application of the current status of the ventilator, monitoring, ventilation mode determines the grade of the ventilator.
(2) According to the size of the hospital is a comprehensive ICU or specialized ICU, estimate the type of admission and treatment, is the application of the unit or medical, teaching and research of large hospitals.
(3) according to the application of ventilator experience, ICU doctor level, do not one-sided acquisition of high-grade machine, ventilator and other medical equipment development, the same, update very quickly, not only to solve the clinical problems, but also to avoid waste of resources. To summarize, the ventilator treatment of intubated patients is a complex systematic project, that is, involving the grade of the ventilator is more related to the level of the doctor using the ventilator, the nurse's respiratory management and the overall strength of the hospital (each auxiliary departments). One-sided pursuit of high-grade machine does not necessarily improve the success rate of respiratory failure rescue.
