Cleaning the Sidestream Pump
To clean the sidestream pump
1. Set etCO
2
measurement mode to Side (for Sidestream monitoring).
2. Remove the etCO
2
module or pod from the monitor.
3. Remove all sidestream sampling tubing from the module or pod connectors.
4. Attach the section of 1/8- or 3/16-inch tubing to the exhaust (sidestream
output) port on the module or pod, and run it to a drainage receptacle placed
below the module.
5. Fill the 60cc catheter-tip syringe with cleaning fluid, and fix it to the
sidestream input connector on the etCO
2
module or pod.
6. Flush the fluid slowly through the pumping system and out through the tubing
connected to the exhaust port. Repeat two more times for a total of 180cc of
fluid.
7. Remove the syringe. Leave remaining fluid in the pumping system for 30
minutes. This disinfects the system.
8. After 30 minutes, fill the syringe with distilled water and flush through the
system. Repeat two more times.
9. Empty the syringe and use it to push several volumes of air slowly through the
system. This clears most of the solution from the pump.
10. Repeat step 9 one or more times to make sure that as much fluid as possible
has been cleared from the system.
11. Remove the syringe from the module or pod, but keep the drain tubing in
place.
CAUTION:
Always use a syringe to flush cleaning solutions through the pump as described
in the instructions below.
Do not attempt to use the sidestream sampling pump itself to move cleaning
solutions through the system. This may cause accelerated wear on the pump
bearings.
