Introduction
1-2 Operator's Manual
The twin micro-piston pump’s ability to deliver a variable flow enables the ventilator to provide a
full range of operating modes and breath types with servo-controlled, leak-compensated PEEP.
Leak compensation helps to improve triggering and avoid auto-triggering when a leak is present.
The ventilator may be used with an endotracheal tube, tracheal tube, face mask, nasal mask or
prongs, or mouthpiece.
There are two models for the HT70 series of ventilators:
•
HT70M : HT70, with oxygen sensor; includes built-in oxygen monitor with alarms
•
HT70PM : HT70 Plus, adds on-airway flow sensor option with graphics, flow trigger, and exhaled
volumes
The HT70M model provides monitoring of inspiratory tidal volume (every breath), inspiratory
minute volume, total respiratory rate, peak pressure, mean pressure, and baseline (PEEP) pressure.
Real-time patient circuit pressure is displayed at all times on the airway pressure gauge on the
face panel. A comprehensive alarm system is built-in to alert the user to violations of user-set or
ventilator safety limits. A built-in oxygen sensor allows monitoring of O
2
with high and low O
2
alarms.
The HT70PM model adds an on-airway flow sensor with on-screen graphics, exhaled tidal and
minute volume monitoring/alarms, and flow trigger. (This manual describes the HT70PM model.)
Gas delivery to the patient may be enriched with oxygen (21%–100%) using either the optional
air oxygen entrainment (50 psi) mixer or optional low flow oxygen reservoir.

Exceptional Mobility
The ventilator’s unique design provides maximum mobility and safety for short- or long-distance
transport of critically ill patients and also for patients who are going about their normal activities of
daily life. This exceptional mobility is derived from two sources: patented, power-conserving dual-
micro-piston technology that eliminates the need for an external compressed gas source, and the
internal dual battery system, which allows virtually continuous use from battery power through hot-
swappable technology.
The ventilator’s micro-pistons use a fraction of the power that is consumed by turbines and blow-
ers. This enables longer battery use time. Our patented system also uses considerably less supple-
mental oxygen than turbine or blower systems, again improving mobility for transport or
homecare use. The superior technology of our micro-piston system over the turbine and blower
systems allow the ventilator to ventilate safely over a wide range of environmental conditions and
altitudes.
The ventilator’s twin micro-piston internal pump is made of mechanically moving components.
As with any other gas delivery system made of moving components, it may emit a minor level of
noise during operation. This is not a malfunction and does not affect the performance of the ven-
tilator.
The internal dual battery system consists of two independent but coordinated lithium ion batter-
ies: the Power Pac battery, located on the back of the ventilator and the backup battery inside the
