1 Introduction
1.1 Overview
Thank you for using the Newport™ HT70 family of ventilators. With the Newport HT70 Ventilator,
you not only get a great ventilator, you get the support of Covidien. We have dedicated our
efforts to providing ventilators that are easy to use, clinically versatile, and cost-effective.
We know that ventilatory support is critical in emergency situations. But for many of our cus-
tomers, it is also a part of their daily lifestyle. The Newport HT70 Ventilators offer home care users
the expanded mobility that allows them to experience more freedom in their lives than many
have known before.
This manual was designed to be comprehensive and still very user-friendly. For the best perfor-
mance from the ventilator, please take the time to review this manual completely.
1.2 Brief Device Description
The Newport HT70 family of ventilators are state-of-the-art ventilators that combine rugged-
ness, ease of use, and clinical proficiency with exceptional mobility to provide ventilatory
support for infant, pediatric, and adult patients in emergency care, transport, subacute care, and
home care applications. They are also ideal for emergency preparedness applications.
The compact, lightweight Newport HT70 Ventilator is built for hard work with a durable polymer
exterior and robust overall design that stands up to harsh environments.
This ventilator defines ease of use with all essential controls at your fingertips using a simple
membrane button and touch screen combination. There are no complicated menus or difficult
sequences to follow to make necessary adjustments for common operations.
A three-tiered management domain system makes it very easy for caregivers to manage all con-
trols while providing quick access to the more essential elements in transport situations and sig-
nificantly enhanced safety and simplicity in the homecare environment.
1.2.1 Sophisticated Clinical Capabilities
In addition to its durability and ease of use, the Newport HT70 Ventilator offers the complete
array of clinical capabilities needed for managing patients.

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 O2with high and low O2
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.
1.2.2 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

Intended Use
Operator's Manual 1-3
ventilator. The internal dual battery system can provide up to 10 hours of operation at standard
settings when new and fully charged. This system assures continued support during transport,
daily activities or power outages.
The detachable Power Pac is “hot-swappable.” That is, if more battery time is needed, a depleted
Power Pac can easily be removed from the back of the ventilator and replaced with a recharged
Power Pac without interrupting ventilation. No tools are needed. The secondary backup battery
maintains operation without interruption when the Power Pac is swapped out and also provides
a minimum of 30 minutes of full operation when all other power sources are depleted. The Power
Pac weighs 2 pounds and is charged anytime the ventilator is connected to an external power
source (AC or DC). It can also be charged separately.
The ventilator may be operated from a variety of AC (100–240 V AC @ 50/60 Hz) or DC (12–24 V
DC) external power sources or from the internal dual battery system. The optional DC auto lighter
power adapter accessory enables connection to an automobile-type DC outlet. Any time the ven-
tilator is connected to external power, both batteries in the internal dual battery system are
charging, whether or not the ventilator is in use.
1.2.3 Travel Certified
The Newport HT70 Ventilator has been tested for and meets requirements for use in helicopter
and fixed wing transport and for use on commercial airlines. Before traveling, be sure to speak
with your airline representative about their particular concerns and clear all of your equipment
with them well before your departure. The labeling that the FAA requires is located on the bottom
of the ventilator.
1.3 Intended Use
Newport HT70 family of ventilators is intended to provide continuous or intermittent positive
pressure mechanical ventilatory support for the care of individuals who require mechanical ven-
tilation through invasive or noninvasive interfaces.
Specifically, the Newport HT70 family of ventilators is applicable for infant, pediatric, and adult
patients greater than or equal to 5 kg (11 lbs) in hospital, sub-acute, emergency department, and
home care environments as well as for transport and emergency response applications.
