Introduction 1
Brief Device Description
The Newport HT70 family of ventilators, hereafter referred to as
HT70, are state of the art ventilators that combine ruggedness,
ease of use and clinical proficiency with exceptional mobility to
provide ventilatory support for infant, pediatric and adult patients in
emergency, critical, subacute and home care applications.
The compact, lightweight HT70 ventilator is built for hard work with a
durable polymer exterior and robust overall design that stands up to
harsh environments.
The HT70 Ventilator defines ease of use with all essential controls at
your fingertips using a simple membrane buttons and touch screen
combination. There are no complicated menus or difficult sequences
to follow in order to make necessary adjustments for common
operations.
A three-tiered management domain system makes it very easy
for critical caregivers to manage all controls while providing quick
access to the more essential elements in transport situations
and significantly enhanced safety and simplicity in the homecare
environment.
Sophisticated Clinical Capabilities
In addition to its durability and ease of use, the HT70 ventilator offers
the complete array of clinical capabilities needed for managing
critical patients.
The dual micro-pistons’ ability to deliver a variable flow enables the
HT70 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 HT70 may be used with an endotracheal tube, tracheal
tube, face mask, nasal mask or prongs, or mouthpiece.
The HT70 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. An optional built-in oxygen sensor allows monitoring of FiO2
with high and low FiO2alarms.

1Introduction
Gas delivery to the patient may be enriched with oxygen (0.21-1.00)
using either the optional Air Oxygen Entrainment (50 psi) Mixer* or
optional Low Flow Oxygen Blending Bag.
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: Newport’s
patented, power conserving dual-micro-piston technology which
eliminates the need for an external compressed gas source, and the
Integrated Battery System which allows virtually continuous use from
battery power through hot-swappable technology.
The HT70’s dual micro-pistons use a fraction of the power that is
consumed by other kinds of gas compressing technology. This allows
batteries to last longer.
The Integrated Battery System consists of two independent but
coordinated lithium ion batteries, the Power Pac battery, located
on the back of the ventilator and the Backup Battery inside the
ventilator. The Integrated 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 HT70 and be replaced with a recharged Power
Pac without interrupting ventilation. No tools are needed. The 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 two pounds and is charged anytime the ventilator is
connected to an external power source (A.C. or D.C.). It can also be
charged separately.
The HT70 may be operated from a variety of A.C. (100-240 VAC @
50 / 60 Hz) or D.C. (12-30 VDC) external power sources or from the
Integrated Battery System. The optional D.C. Auto Lighter Power
Adapter accessory enables connection to an automobile-type D.C.
outlet. Any time the ventilator is connected to external power, both
batteries in the Integrated Battery System are charged, even while
the ventilator is in use.

helicopter and fixed wing transport. Before traveling, be sure to
speak with your airline representative about their particular concerns
and clear all your equipment with them well before your departure.
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 ventilation 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).
The Newport HT70 family of ventilators is suitable for use in hospital,
sub-acute, emergency room, and home care environments as well as
for transport and emergency response applications.

1Introduction
General Cautions
Do not place liquids on or near the ventilator.
Damage can occur if the HT70 is exposed to extreme temperatures.
Do not store the HT70 in areas where it may be exposed to
temperatures below -40° C (-40° F) or above 65° C (149° F).
General Warnings
The design of the HT70 ventilator, the Operating and Service
manuals, and the labeling on the ventilator take into consideration
that the purchase and use of the equipment is restricted to trained
professionals, and that certain inherent characteristics of the
ventilator are known to the operator. Instructions, warnings and
caution statements are therefore limited to the specifics of the HT70.
This manual excludes references to various hazards which are
obvious to medical professionals and operators of this equipment
including consequences of product misuse, and potential adverse
effects in patients with abnormal conditions.
Transport of patients with the HT70 requires that medical staff
have a good working knowledge of the ventilator’s use and
problem resolution. Proper emergency backup equipment must be
immediately available during transport.
Product modification or misuse can be dangerous. Newport Medical
Instruments, Inc. disclaims all liability for the consequences of
product alterations or modifications, as well as for the consequences
which might result from the combination of this ventilator with other
products, whether supplied by Newport or by other manufacturers,
unless such a combination has been specifically endorsed by
Newport Medical.
There is a risk of explosion if used in the presence of flammable
anesthetics.
A patient connected to a ventilator requires the constant attention of
trained caregivers to the patient’s condition.
Always have an alternate power source and means of ventilation
available when the ventilator is in use in case of a mechanical or
system problem.

Introduction 1
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 FiO2alarms 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.
