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 FiO2 alarms.
