c) Complete this step using one of the methods below:
i) If using test equipment that automatically triggers a breath follow the manufacturer's instructions for operation of the
test equipment. Record the average bolus reading.
ii) If manually triggering breaths, note and record the bolus size in mL of each breath. Repeat 5 times. Average the five
bolus measurements and record the average reading. You may need to "zero" the testing device between triggering a
simulated breath.
d) Adjust the SAROS to a setting of P96 (96mL).
e) Repeat steps B & C for the P96 testing.
3.2.3 Battery Run Time Test
1) Test battery run time using the following procedure:
a) Fully charge the battery via AC power by leaving it connected to AC power for a minimum of 1 hour. After 1 hour, verify the
power cartridge status indicator is fully illuminated and no longer displays a waterfall motion.
b) Disconnect the AC power. Power the SAROS on at C3 (3.0 LPM) and start a timer.
c) Allow the unit to continue to run until it shuts off.
d) Once the unit shuts off completely, stop the timer and record the battery duration.
e) Verify that the time recorded is >24 minutes
NOTE: The nominal capacity of a new battery is 30 minutes at setting C3. A battery is considered within its useful life if its duration is
80% of the nominal capacity of a new battery (24 minutes at C3).
