Introdução
Use this guide to ensure the CoughAssist works after a replacement, or when you don’t know what’s wrong and need to troubleshoot. The steps will take you through, testing all of the functions of the device separately, making it easy to find what isn’t working correctly. The first half of the procedure can also be done on the CoughAssist CM series.
-
-
Block the connector on the front of the machine using a rubber plug or similar item.
-
Check the pressure gauge. If it is not zero, see “pressure gauge reading is wrong” on the troubleshooting guide.
-
Set the inhale pressure knob fully clockwise, and the inhale flow and pressure knobs fully counterclockwise. On the CA models, set the manual/auto switch to manual, and set each timing knob to 1 second.
-
-
-
Reset the pressure knob counterclockwise, then set the control lever to inhale and check that the gauge reads between 2 and 5 cmH2O.
-
Move the control lever to exhale and note that the gauge reads between -2 and -5 cmH2O.
-
Repeat the inhale and exhale tests with the pressure knob fully clockwise, seeing if the gauge is between 57 and 63 cmH2O.
-
Release the control lever and note that the lever moves to the center and pressure drops immediately to 0 cmH2O.
-
If any of these pressures are wrong, see “limited pressure” on the troubleshooting guide.

-
5. Turn the pressure knob fully clockwise, set the control lever to inhale, remember the gauge reading, and release the control lever.
-
Set inhale flow to minimum (clockwise). Set the control lever to inhale and check that the pressure is within 10 cmH2O below the previous reading (maximum flow).
