What causes low oxygen concentration (continued) in Invacare Medical Equipment?
- SShelby AndersonSep 7, 2025
Continued low oxygen concentration may be due to: * A P.C. board shifting at wrong pressures: Check pressure at the product tank. If not, replace the P.C. Board. * Flowmeter issues: Adjust the flowmeter to the maximum setting, replace a cracked fitting, or repair/replace leaking input tubing. * Timing issues: An adjustable timer is used to control the shifting of the Pressure Equalization (P.E.) valve. * P.E. valve problems: Replace the P.E. valve if there's a bad coil or restrictor blockage. * Kinks or tears in P.C. board restrictor tubing: Replace the P.C. board.
