Introduction
Brief Device Description
The Newport HT70 family of ventilators are state of the art ventilators
that combine ruggedness, ease of use and clinical prociency 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 denes 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 difcult 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 signicantly 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.
Specically, 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.

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 specics 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

Introduction
Product modication or misuse can be dangerous. Newport Medical
Instruments, Inc. disclaims all liability for the consequences of
product alterations or modications, 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 specically 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 sufcient 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.
1
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 Verication
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.

Front Panel Overview
Please refer to Foldout drawing F-1 at the front of the manual. The
HT70 front panel consists of easy access membrane buttons, LED
indicators and the patient connection manifold. The center touch
screen panel provides access to alarm and parameter settings. The
HT70 Plus model has the added port for connecting the on-airway
ow sensor. This manual describes the HT70 Plus full features.
Touch Screen Overview (Hospital Domain)
Please refer to Foldout drawing F-3 at the front of the manual. The
HT70 touch screen includes direct access to essential screens for
setting patient parameters and alarms. Simple menu navigation
allows access to advanced features and utility screens.
NOTE:
While operating on internal battery power, when the Power
Save feature is ON and there are no active alarms, the touch screen
will go to sleep after two minutes. Just touch the screen or any
membrane button to bring it back into view.
Internal Dual Battery System Overview
The Internal Dual Battery System can provide up to 10 hours of
operation when new and fully charged (under standard conditions
shown in Section 7) and consists of two independent but coordinated
lithium ion batteries; the hot swappable Power Pac battery and
the secondary Backup Battery. When external power is lost, the
ventilator will run on the Power Pac until the “Switching to Backup
Battery” alarm activates. The Backup Battery will then provide a
minimum of 30 minutes of emergency back up power. The Backup
Battery portion of the system also maintains operation without
interruption whenever the Power Pac is swapped out. The Power Pac
can be recharged independently from the ventilator. The Power Pac
has an LED on the bottom edge to show charge condition. Push the
button to see charge condition. Green = approximately 90% or higher
charge level, Amber = charge not completed, Red = battery depleted.
Always insert the Power Pac onto the HT70 and power it ON to verify

DC Auto Lighter Power Adapter (optional)
The DC Auto Lighter Power Adapter (p/n ADP3203P) is used to plug
the HT70 into any vehicle’s DC power outlet (12 VDC to 16 VDC). The
external DC source of power will not only power the ventilator but
also charge both batteries in the Internal Dual Battery System.
This cable can also be used to connect the HT70 Ventilator to
other external batteries (12 VDC to 16 VDC) when combined with
an alligator clip adapter that is available from common electronics
outlets such as Radio Shack.
To use the DC Auto Lighter Power Adapter, plug the adapter’s pinchrelease power plug into the external power supply input located on
the lower left corner of the Power Pac battery pack. Ensure that the
cord is to the right of the plug and that it locks in place securely. Plug
the other end of the adapter into a vehicles autolighter power outlet
(12 VDC to 16 VDC).
To remove the DC Auto Lighter Power Adapter from the external
power supply input, gently pinch the connector to release the locking
pin and then pull the plug out.
Water in the oxygen supply can cause equipment
Aequitron Remote Alarm Cable
The Aequitron Remote Alarm Cable allows the user to connect the
HT70 Ventilator to the Aequitron 6217 remote alarm assembly.
This cable must be connected to both the nurse call and USB
output ports on the ventilator. The other end of this cable must be
connected to the original extension cable (not to the Aequitron unit
itself).
The ventilator must be congured to “Norm Close” (see Figure 4 on
page 4-18). In addition, see the General Notes regarding nurse call
connectivity on page 1-5.
Complete a self-test after the cable has been installed and at regular
intervals to ensure the Aequitron system is operating as intended. A
self-test consists of inducing an alarm and conrming the Aequitron
unit emits an audio alarm, and also conrming the audio alarm
ceases once the alarm in the ventilator has been reset.

Touchscreen (Graphical User Interface) Layout
The touchcreen display is color coded so that it is very easy to
differentiate between basic ventilation settings which are green, alarm
settings which are red and monitored values which are yellow (on blue
background). The “More” and “Utility” settings are in blue.
If the power save feature is enabled, the HT70’s touch screen will go
dark if not touched for 2 minutes (while running on internal battery). To
bring it back into full view just touch the screen or a membrane button.
Primary Screen Navigation
The buttons for accessing Alarms, Main, and More screens as well as
the buttons for selecting mode and breath type are consolidated along
the left margin. Monitored values are displayed across the bottom
margin and the pressure bar graph rises and falls along the right. This
leaves plenty of room for the display in the middle of the screen.
The name of the active screen is written in larger letters than the other
two. To change to a different screen view, just touch one of the other
screen buttons. There is no need to press Accept.

2. Ensure the ventilator, patient circuit and accessories are
assembled correctly. (See Section 3)
3. Make sure HT70 has passed the Quick Check Procedure.
4. Perform the Circuit Check. Resolve any issues. (See Section 4)
5. Set all parameters per physician’s prescription using manual
adjustment or a Custom or Default Preset. See Section 9 for
specications on all settings.
a. Select mode and breath type. Then set all parameters on
the Main Screen and relevant parameters on the More
Screen.
b. Select safe/appropriate alarm limits on the Alarms Screen.

and volume delivery for pressure breaths will be different than they
will be on the patient. Pressure Support breaths will not perform the
same way they do on patients. And PEEP may cause auto-triggering.
These differences may cause nuisance alarms during this step.
8. When you are ready, remove the test lung and attach the patient
connection of the breathing circuit to the patient interface.
9. Monitor the patient settings and check for appropriate alarm
settings.

Operating the Ventilator
Problem/ Area
of Concern
Autotriggering
(at a typical
trigger
setting)
(green trigger
light illuminates
when there
is no patient
effort)
In SIMV
or SPONT
modes, some
or all breaths
seem to last
extra long
Occlusion
Alarm/
Sustained
Occlusion
Alarm
The patient
will not be
ventilated.
Manually
ventilate the
patient until
this is resolved.
High (Peak)
Pressure
Alarm
This alarm
violation stops
breath delivery
until pressure
drops
Probable
Cause
Circuit and/or
airway leak
Leak is causing
ow to remain
high during
pressure
support breath
delivery, so
the PS Exp.
Threshold (ow
cycling off
threshold) is
never met
The patient’s
expiratory
gas pathway
is occluded
or partially
occluded
Coughing
/ need for
airway care or
bronchodilator
treatment
Secretions
too dry due
to inadequate
humidity
Resolution
Check for and resolve leaks if
unintentional.
If airway leak is intentional, turn on
NIV and adjust Bias Flow/Trigger
settings so that the patient can trigger
effectively without auto-triggering.
Consider using the Flow Sensor and
Flow Trigger.
Eliminate circuit leaks
Set the PS Max i-Time control to limit
the breath delivery to a reasonable
inspiratory time
Evaluate everything in the patient’s
pathway of exhalation to determine
what is causing resistance and
resolve the issue
Change HME and/or expiratory lter
if used
Change the exhalation valve
Unkink expiratory drive line
Replace ow sensor
Perform suctioning/airway care, or if
due and prescribed, give prescribed
bronchodilator treatment
Use heated humidier with
appropriate temperature setting and
keep tubing warm
