Time/usage
The most significant setting that affects battery use time is Power Save. If Power Save is off, battery
use time is decreased by about 30%. When Power Save is on, the screen will go to sleep (go blank)
to save energy. An active alarm will temporarily end Power Save, and the screen will become
active. Power Save will resume 2 minutes after the alarm condition is resolved.
Peak pressures and respiratory rate also affect battery use time. If the peak pressure rises above 30
cmH
2
O consistently and the respiratory rate is above 20, expect to lose another 15% to 25% of the
battery use time.
Using PEEP means that the bias flow will be in use. As this means that the twin pistons will run
during both inspiration and exhalation, battery time will be shorter with PEEP on.
As the batteries age with use, the time that the ventilator will operate on battery power from a
fully charged state will decrease. Replace the Power Pac battery pack every 24 months or sooner
if battery operation time is insufficient for usage.
If the ventilator will be powered from the Power Pac battery pack for an extended period, ensure
that the battery pack is fully charged prior to use.

Note:
Covidien recommends carrying at least one extra, fully charged Power Pac during transport or outdoor
applications.

Check Battery Charge Level/Battery Time Estimator
Before using the Newport HT70 Ventilator for transport or when planning to use the internal dual
battery system as the primary power source, always check the Power Pac and backup battery
charge condition. The charge level indicator on the touch screen shows the percent of charge
available. A blue battery icon indicates the status for the Power Pac battery pack, and a red battery
icon indicates the status for the backup battery. A gray battery icon with a red question mark indi-
cates there was a loss of communication between the ventilator and the Power Pac battery. To
view the backup battery condition, temporarily remove the Power Pac.
Also check the battery time estimator displayed on the monitoring screen. When the ventilator is
disconnected from external power, this indicator shows the estimated time remaining based on
the current ventilation settings.
