The main mechanical ventilation mode:
1. Interstitial positive pressure ventilation (IPPV): positive pressure in the inspiratory phase, zero pressure in the expiratory pressure.
2. Interstitial positive and negative pressure ventilation (IPNPV): the inspiratory phase is positive pressure and the expiratory phase is negative pressure.
3. Continuous positive airway ventilation (CPAP): refers to the patient's spontaneous breathing, the entire respiratory cycle, are artificially given a certain positive pressure in the airway.
4. Intermittent command ventilation and synchronous intermittent mandatory ventilation (IMV/SIMV) ①. IMV: There is no synchronizing device. The ventilator air supply does not require the patient's spontaneous breathing trigger. The time of each air supply in the breathing cycle is not constant. ②. SIMV: There is a synchronizing device. The ventilator gives the patient a mandatory breath according to the pre-designed breathing parameters every minute. The patient can have spontaneous breathing and is not affected by the ventilator.
5. Instructional minute ventilation (MMV)
6. Pressure-supported ventilation (PSV): Under the premise of spontaneous breathing, each inhalation receives a certain level of pressure support, increasing the patient's inspiratory depth and the amount of gas absorbed.
7. Volume Support Ventilation (VSV)
8. Pressure regulation capacity control
9. Biphasic or bi-level positive pressure ventilation
