Running the NIPPY on Battery Power
The NIPPY + may be powered from the mains, internal or external battery.
IMPORTANT BATTERY CARE RULES
1. Regularly check battery run times for your system at your prescription settings
and record in the log.
2. If you have more than one ventilator, check this one too.
3. Never check the on-screen run time estimate when running on mains power.
4. Failure to perform regular battery performance checks could result in failure
during loss of mains power. Check Monthly.
5. Know the difference between battery run time and battery state of health. The
run time is the running time expected from a healthy battery. The state of
health is the condition of the battery in terms of its total service life.
Power Source Priority
1. - Mains Electricity
2. - External Battery (if connected)
3. - Internal Battery (if fitted)
In order to save battery power, the ventilator will always run on mains electricity
if it is present.
If the mains fails or is not connected, the ventilator will select the external battery
as the next choice. The external battery, if present, will always be run flat before
the internal battery is selected.
If there is no external battery, the ventilator will switch to its internal battery.
If there is no internal battery the ventilator will shut down and alarm to warn of
power failure.
Battery Run Times
Battery run times are dependent on the battery age, condition, ambient
temperature, ventilator settings and amount of leak. High pressures and /or high
breath rates use more power and therefore shorten run times. Large leaks use
more power and shorten run times.
Run times will gradually reduce as the battery ages regardless of how
much use the battery has had.
Battery run times will typically be 20% more in IPPV mode because of the
absence of the exhale port leak.
