5 alarm function.
5.1 Intelligent alarm system, which is divided into high, medium and low alarm levels, can be clearly distinguished in sound and detailed information is displayed on the screen.
5.2 alarm of upper and lower limit of airway pressure, upper and lower limit of ventilation, upper and lower limit of oxygen concentration, continuous positive pressure alarm, asphyxiation alarm, power interruption alarm, gas source interruption alarm, 120s alarm mute.
5.3 when the airway pressure reaches the upper limit, the inspiratory pressure can be stopped immediately and converted to the expiratory state, and an alarm can be issued when it is lower than the set lower limit and lasts for 12 seconds.
5.4 when the temperature of the inhaled gas exceeds 40 ℃, the ventilator should issue an alarm.
5.5 when the air supply is interrupted, the ventilator should send out an advanced alarm signal within a period of not more than 15s.
