Introduction

Brief Device Description

The Newport HT70 family of ventilators are state of the art ventilators
that combine ruggedness, ease of use and clinical prociency with
exceptional mobility to provide ventilatory support for infant, pediatric
and adult patients in emergency care, transport, critical care,
subacute care and home care applications. They are also ideal for
emergency preparedness 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 denes ease of use with all essential controls at
your ngertips using a simple membrane button and touch screen
combination. There are no complicated menus or difcult 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 signicantly enhanced safety and simplicity in the homecare
environment.

1

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 twin micro-piston pump’s ability to deliver a variable ow 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.

There are 3 models for the HT70 series of ventilators:

HT70S HT70 Basic for use when Pressure Support is not
needed.
HT70 HT70 Classic, adds Pressure Support and related
parameters and Trends screen
HT70PM HT70 Plus, adds on-airway ow sensor option with
graphics, ow trigger and exhaled volumes

The HT70 Basic and Classic models provide 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

Introduction

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 O2 with high and low O2 alarms.

The HT70 Plus model adds an on-airway ow sensor with onscreen
graphics, exhaled tidal and minute volume monitoring/alarms, and ow
trigger. This manual describes the HT70 Plus model and will denote
features that are not available on the HT70 and HT70S models.

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 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: Newport’s patented,
power conserving dual-micro-piston technology which 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 HT70’s micro-pistons use a fraction of the power that is
consumed by turbines and blowers. This enables longer battery use
time. Our patented system also uses considerably less supplemental
oxygen than turbine or blower systems, again improving mobility for
transport or homecare use. The superior technology of our micro­piston system over the turbine and blower systems allow the HT70
to ventilate safely over a wide range of environmental conditions and
altitudes.

The HT70’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 ventilator.

The Internal Dual 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 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.

Introduction

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 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 two pounds and is charged anytime the ventilator is connected
to an external power source (AC or DC). It can also be charged
separately.

The HT70 may be operated from a variety of AC (100-240 VAC @ 50 /
60 Hz) or DC (12-24 VDC) 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 ventilator is connected to external power, both batteries in
the Internal Dual Battery System are charging, whether or not the
ventilator is in use.

Travel Certified

1

The HT70 has been tested for and meets requirements for use in
helicopter and xed 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 to
be on the ventilator is located on the bottom of the HT70.

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.

Specically, 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.

NOTE:

Federal law (US) restricts sale by or on the order of a physician.

General Notes

The Newport HT70 has been designed to accommodate connectivity
with nurse call/monitoring systems. Because it is not possible to
anticipate every conguration of hardware and software associated
with nurse call/monitoring system, it is the user’s responsibility to
conrm proper functionality of the system when used in conjunction
with the HT70. Verication of alarms, alerts and patient data
transmissions is required. If the system performance is not as
expected, contact Newport Medical Technical Support for assistance
troubleshooting the set-up. Do not use the HT70 ventilator with a
nurse call/monitoring system until the functionality of the ventilator/
system combination has been conrmed.

General Cautions

Do not place liquids on or near the ventilator.

A caution describes a condition that can cause damage to

A note emphasizes information that is important or

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).

To avoid the risk of electric shock, the ventilator should not be
opened by anyone other than an approved service provider.

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 specics 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.

Introduction

Product modication or misuse can be dangerous. Newport Medical
Instruments, Inc. disclaims all liability for the consequences of
product alterations or modications, 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 specically endorsed by
Newport Medical. There is a risk of explosion if used in the presence
of ammable anesthetics.

A patient connected to a ventilator requires the constant attention of
trained caregivers to the patient’s condition.

Ventilator alarms are a critical element in the safety net of patient
care. It is extremely important for patient safety that caregivers
immediately identify and correct alarm violations.

Always have an alternate power source and means of ventilation
available when the ventilator is in use so that they are easy to access
in case of a mechanical or system problem.

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 sufcient 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 and Low Flow Oxygen
Reservoir are 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 Reservoir.

To avoid putting stress on the internal pump and compromising
gas delivery to the patient, ensure that the Air/Oxygen Entrainment
Mixer is not connected to the gas intake port on the ventilator when
performing a Circuit Check. Ensure that the oxygen supply is enabled
any time the optional Air/Oxygen Entrainment Mixer is secured in
place while ventilating.

Introduction

Calibrated oxygen monitoring at clinically appropriate levels is
required for patient safety when supplemental oxygen is in use. The
optional built-in oxygen sensor on the HT70 allows High and Low O2
alarms to be enabled which can be used to assure proper oxygen
de livery.

Always plug the HT70 into an external power supply source whenever
it is available, even when HT70 is not in use, to keep the Internal
Dual Battery System fully charged and to ensure best battery
performance. Check battery capacity on the front panel before
detaching from external power.

When installing a replacement Power Pac during battery operation,
always ensure that the charge level LED on the replacement pack is
green, indicating 90% or higher charge level.

Always ensure that the green External Power LED lights when the
ventilator is connected to an external AC or DC power source.

To maintain grounding integrity when using AC power, only connect
to properly grounded receptacles.

Use only the Newport supplied AC Power Supply (p/n PWR3204P)
with the HT70 ventilator and HT70 Power Pac (p/n BAT3271A).

Always disconnect the external power supply prior to servicing.

After servicing the HT70, it must pass the Operational Verication
Procedure (OVP) before it is returned to patient use. See the HT70
Service Manual.

Do not use electrically conductive breathing circuits. Always use
clean and dry breathing circuits.

Always use a clean, dry lter in the following locations: a standard
bacteria lter on the gas output, a prox line (bacteria) lter on the
proximal pressure tubing port and an intake (bacteria) lter behind
the lter cover.

Adding attachments or other components or sub-assemblies to the
ventilator breathing circuit system can increase the patient’s work of
breathing and/or add resistance to patient exhalation.

Always ensure that the audible alarm loudness level is set at a
volume that can be heard by the caregiver. Do not use the ventilator
in an environment where audible alarms cannot be heard by the
caregivers.
