    What to do if my Invacare Oxygen Equipment alarm is continuous?
    • M
      Matthew KnightAug 15, 2025
      If your Invacare Oxygen Equipment is emitting a continuous alarm, it could be due to several reasons: * The unit may be overheating because the air intake is blocked. To resolve this, remove and clean the cabinet filters and ensure the concentrator is at least three inches away from walls, draperies, or furniture. * There might be insufficient power at the outlet. Avoid using extension cords and try a different electrical outlet or circuit. * In some cases, internal repairs may be required, and you should call your Service Provider.

      If your Invacare Oxygen Equipment is emitting short beeps followed by a long pause, it indicates a main power loss. Here’s what you can do: 1. Ensure the power cord is properly plugged into the outlet. If it isn't, insert the plug into the outlet. 2. Check if there is power at the outlet. Inspect the house circuit breakers or fuses. If the problem continues, try using a different outlet. 3. If a circuit breaker has tripped, call your Service Provider.

    What to do if my Invacare Oxygen Equipment is beeping rapidly?
    • L
      Lisa MorrisAug 21, 2025
      If your Invacare Oxygen Equipment is alarming with rapid beeps, it typically indicates a low flow. Here’s how to address it: 1. Check for any kinks or blockages in the tubing, cannula, or humidifier. If you find any, correct, clean, or replace the item. Afterward, turn the power off for 60 seconds and then turn it back on. 2. Verify that the flowmeter is not set at 0.5 L/min or less. If it is, reset the flowmeter to the prescribed flow rate. Note: If the prescribed flow rate is below 0.5 L/min, use the Pediatric Flowmeter IRCPF16 (Only with Perfecto 5).

      If the Invacare Medical Equipment alarm sounds continuously, it indicates a system failure. This may be due to the unit overheating because of a blocked air intake, insufficient power at the outlet, or internal repairs being required. Try the following: 1. Clean the cabinet filters or move the oxygen concentrator at least 12 inches away from walls, draperies, or furniture. 2. Avoid using extension cords and try a different electrical outlet or circuit. 3. If the problem persists, contact your service provider.

    • V
      vtoddSep 2, 2025
      If your Invacare Medical Equipment alarm is sounding with rapid beeps, it indicates a potential obstruction. This could be due to an internal obstruction in the oxygen path, such as kinked or blocked tubing, cannula, or humidifier, or the flowmeter being set at 0.5 L/min or less. Here's how to address it: 1. Check for any kinks or blockages in the tubing, cannula, or humidifier. Correct, clean, or replace the affected item. After doing so, turn the power off for 60 seconds and then turn it back on. 2. Ensure the flowmeter is set to the prescribed flow rate. If the prescribed rate is below 0.5 L/min, use the Pediatric Flowmeter IRCPF16 (only with Perfecto2 5). Note: Using the pediatric flowmeter will deactivate the Potential Obstruction Alert.

      nicolelawrenceSep 5, 2025
      An alarm with short beeps and a long pause on your Invacare Medical Equipment indicates a main power loss. This could be due to the power cord not being plugged in, no power at the outlet, or a tripped circuit breaker. To resolve this: 1. Ensure the plug is fully inserted into the outlet. 2. Inspect the house circuit breakers or fuses. If the problem continues, try a different outlet. 3. Reset the circuit breaker. If it trips again, contact your service provider.

    • A
      alexandra30Dec 1, 2025
      A YELLOW or RED light illuminated on your Invacare Medical Equipment indicates a system failure. This can be due to several reasons: * Low oxygen purity. * Kinked or blocked tubing, cannula, or humidifier. * Flowmeter set at 0.5 L/min or less. * Unit overheating due to blocked air intake. * Insufficient power at outlet. * Internal repairs required. Here's what you can do: 1. Clean or replace the filters. 2. Inspect for and correct any kinks or blockages in the tubing, cannula, or humidifier. Then, turn the power off for 60 seconds and back on. 3. Ensure the flowmeter is set to 1.0 L/min or more. 4. Clean the cabinet filters or move the concentrator at least 12 inches away from obstructions. 5. Avoid using extension cords; use a different electrical outlet or circuit. 6....
