A.C. power at which time the built-in humidifier can be used.
Do not use electrically conductive patient circuits.
Always use a clean patient circuit.
Always use an inline filter (p/n HT6004701 or equivalent) at the
Airway Pressure Connector to protect the internal transducers from
moisture or other contaminants.
Always use appropriate monitors to ensure sufficient oxygenation
and ventilation (such as pulse oximeter and/or capnograph) when
the HT50 Ventilator is in use on a patient.
The ventilator is ready for operation only when:
a) It is completely assembled, and;
b) The Quick Check Procedure, including the Exhalation Valve
