What are the common modes of emergency ventilator?
IPPV (Intermittent Positive Pressure Ventilation)
Parameters: Tidal volume/minute ventilation, respiration rate, inhalation/respiration ratio, PEEP, pressure ceiling
Setting: adult, 600~1000ml/6~12L/ min, 10~15 times/min, 1:1~1:2.5, non-invasive/invasive: 20/40~50cmH2O
A/C(auxiliary/controlled ventilation)
Setting: respiratory rate of 8~12 times/minute, tidal volume: the patient’s respiratory rate is fast and should be small; Slow, preferably large — preferably measured in minutes of ventilation
Minute ventilation is difficult to control
SIMV (Synchronous Intermittent Command Ventilation)
Setting: First observe the intensity and frequency of the patient’s spontaneous breathing; Aim for adequate minute air flow
The increase in forced ventilation is the supplementary minute ventilation
Minute ventilation is well controlled

What are the common modes of emergency ventilator?
PCV (pressure control ventilation)
Parameters: inspiratory pressure, respiration rate, inhalation/respiration ratio, PEEP, pressure upper limit
Setting: adult, non-invasive/invasive: 15~30/<40cmH2O, 10~15 times/min, 1:1~1:2.5, non-invasive/invasive: 20/40~50cmH2O
PSV(Pressure Support Ventilation)
Setting: inspiratory pressure, PEEP, pressure upper limit
PRVC (Pressure Supported Volume Assured Ventilation)
Setting: Tide volume, inspiratory pressure, PEEP, pressure upper limit
