Visit from Servicing Engineer

The engineer came to service the Bi-pap and the cough assist machine. Both were in good condition. The engineer took readings from both machines and changed the filter in the Bi-pap. While he was here we asked him about the whistling noise coming from the replacement hose that Wy Hospital had sent to us. He was immediately familiar with the problem and explained that the respironics hose has a smoother interior and as a result is more prone to breaks and tears. The replacement hose is more durable but its flexibility comes from its ridged interior. These contours in the replacement hose are what cause the vibrations which we hear as a high pitched wail.
