Introduction

If a fault is detected in the ventilator and its life support functions are
in doubt, immediately discontinue use; use an alternative method of
ventilation until the fault has been corrected. Contact your service
provider immediately.
Do not block the Emergency Gas Intake (on the bottom panel) or the
Fresh Gas Intake Port (on the right side panel).
Always use appropriate monitors to ensure sufficient oxygenation
and ventilation (such as a pulse oximeter and/or a capnograph) when
the HT70 Ventilator is in use on a patient.
The optional Air/Oxygen Entrainment Mixer* is designed to operate
with medical grade oxygen.
Ensure that the oxygen source is not empty before and during the
use of the optional Air/Oxygen Entrainment Mixer* or Low Flow
Oxygen Blending Bag.
When the optional Air/Oxygen Entrainment Mixer* is secured in place,
ensure that the oxygen supply is enabled prior to powering the HT70
on to avoid putting stress on the internal pump and compromising
gas delivery to the patient.
Continuous oxygen monitoring is required for patient safety when
oxygen is in use. The optional built-in oxygen sensor on the HT70
alows High and Low FiO2 alarms to be enabled which can be used to
assure proper oxygen delivery.
Always plug the HT70 into an external power supply source whenever
it is available, even when not in use, to keep the Integrated Battery
System fully charged and to ensure best battery performance.
Check battery capacity on the front panel before detaching from
external power.
Always ensure that the green External Power LED lights after
connecting the ventilator to an external A.C. or D.C. power source.
To maintain grounding integrity when using A.C. power, only connect
to properly grounded receptacles.
Use only the Newport supplied A.C. Power Supply (p/n PWR3200)
with the HT70 ventilator.
Always disconnect the external power supply prior to servicing.
