Operator & Service Manual
F) Record a 60 second running average for the flow rate. Verify the 60 second average is within 1.80 - 2.20 LPM. If using a non-Argon
or Non-BTP compensated measuring device, verify the 60 second average is within 1.70 - 2.10 LPM.
NOTE: It is not required to test flow and concentration at 1LPM for performance verification. This is not a typical clinical use case.
2) Verify functionality of the device in pulse dose mode using the following procedure:
a) Adjust the SAROS to a setting of P48 (48mL).
b) Trigger a simulated breath by folding and pinching the tubing* running from the SAROS to the testing device. Verify the
breath is triggered by the light blinking adjacent to the pulse flow mode button.
*Other acceptable procedures to trigger a breath may include connecting a tee to a breath simulator (syringe, jet venturi,
nasal cannula, etc.). If you are using a tee, the tubing to the breath simulation device should not exceed 2 inches in
length.
c) 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 oxygen anylizer 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.
f) Average the five bolus measurements and record the average reading.
6.6.3 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).
