Why does Invacare Perfecto 2 SeriesIRC5PO2AW Medical Equipment have low concentration even after checking purity?
- T
  Thomas SmithSep 12, 2025
  If your Invacare Medical Equipment has low concentration and you've already checked for oxygen purity, the flowmeter may be the issue. If the flowmeter is opened beyond the maximum flow rate, return it to the maximum setting. If there is a cracked or broken fitting, replace the fitting. If the input tubing is leaking or loose, repair or replace it. Additionally, the P.E. valve could be faulty, with a bad coil or a restrictor blockage, in which case you should replace the P.E. valve. Finally, inspect the P.C. board restrictor tubing for kinks or tears and replace the P.C. board if necessary.

Why doesn't the obstruction alert activate on my Invacare Perfecto 2 SeriesIRC5PO2AW Medical Equipment?
- M
  Mike CooperSep 14, 2025
  If the Possible Obstruction Alert on your Invacare Medical Equipment does not activate on flows less than 0.5 L/min, there may be a system leak. Repair any leaks in the product tank, regulator, tubing, fittings, or flow meter. Alternatively, the check valves may be defective, requiring replacement.
