Manual Revision History

Thank you for using the Newport HT70 family of ventilators. With
the HT70 you not only get a great ventilator, you get the support
of Newport Medical. Since 1981 we have maintained a focused
commitment to the design, production and sale of ventilators. 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 and critical
care situations. But for many of our customers, it is also a part of
their daily lifestyle. The HT70 Ventilators offer home care users the
expanded mobility that allows them to experience more freedom in
their lives than many have ever known before.
We have designed this manual to be comprehensive and still very
user friendly. For the best performance from your HT70 Ventilator,
please take the time to review this manual completely.
