Alarms alert clinicians to changes in the patient or ventilator, including:
Ventilator
Low Gas Pressure - Gas supply pressure is below 30 psi.
Loss of PIP - Peak pressure is 25% below set point.
High PIP - Peak pressure is 5 cm H20
above set point.
Cannot Meet PIP - Peak pressure cannot be reached, or held stable;
or maximum servo pressure (19.6 psi) has been reached.
Jet Valve Fault - Electronic signal to inhalation valve has failed.
Ventilator Fault - Code indicates different electronic failures.
High/Low MAP - Mean airway pressure is outside limits.
High/Low Servo Pressure - Servo pressure is outside limits.
Power Disconnect - Electrical power supply has been disrupted.
Standby - Indicates when ventilator has been put in pause mode.
Humidifier
High/Low Temperature - Circuit or cartridge temperature is outside
limits.
High/Low Water Level - Water in cartridge is above or below normal
level.
Circuit Fault - Electronic component in circuit has failed.
Alarms are divided into two groups serious and not so serious. Serious
alarms indicate a potential hazard to the patient. These alarms stop
ventilation and put the Life Pulse in standby. Less serious alarms allow
the Life Pulse to continue support to the patient while alerting the
clinician there has been a change in the patient or the ventilator.
