When the violation is no longer in effect, the alarm message latches (remains steadily visible) until
it is reset by pressing the
Audio Paused/Reset button.

Audio Paused/Reset Button
Press the Audio Paused/Reset button to mute the audible alarm for 1 minute (60 sec). Once an
alarm condition is corrected, press this button to clear (reset) the alarm message. Press repeatedly
to clear multiple messages. Press and hold for 3 seconds to clear all alarm messages at once.

+ only available on the HT70PM when the on-airway flow sensor is in use
The HT70M model ventilator monitors the volume of gas output from the ventilator; therefore,
the High and Low Inspiratory Minute Volume alarms respond to changes in delivered, not
exhaled, volumes. For this model, use the High Inspiratory Minute Volume Alarm (
1
Min Vol) to
detect leaks or disconnects while using pressure-controlled ventilation, and use the Low Pressure
Alarm (
3
P) to detect circuit leaks or disconnect while using volume-controlled ventilation.
For the HT70PM model, if the on-airway flow sensor is in use, the sensor measures exhaled vol-
umes. So in this case, the ventilator will automatically display exhaled tidal volume and exhaled
minute volume, and the alarms will respond accordingly. That is, when the on-airway flow sensor
is in use, the Low Minute Volume alarm will respond to leaks and disconnects when minute
volume leaving the patient drops to the alarm setting. If exhaled volumes are important to the
care of the patient, Covidien recommends the HT70PM model with the on-airway flow sensor. To
verify exhaled volumes when not using the flow sensor, use a separate exhaled volume monitor.
