Hose Length

Now easy on the jokes

I'am considerating ordering a longer hose to help with the location and set-up of my equipment.I currently have a six foot hose.My question would be..is there any pressure issues I should be concerned with going to a longer connection?Thanks

I have read that for CPAP; 8' hoses are no problem, 10' shouldn't cause problems, and 12' may be OK.

An APAP will automatically compensate for the pressure drop. Data from the machine will need to be monitored to ensure that the machine can handle the increased hose length, and it may be necessary to adjust the maximum pressure.

With a CPAP it is more difficult to measure the pressure drop caused by a longer hose. The pressure drop is directly impacted by how much air is vented from the mask end of the hose; the more air that is vented, the greater the pressure drop. If you connect a very long hose to a CPAP machine and have no leaks or venting, the pressure at both ends of the hose will be the same. The problem comes in when air is vented from the mask end of the hose, typically by the CO2 washout vents, leakage, and by breathing. In order to accurately measure the increased pressure drop, the pressure will need to be measured at the mask while the user is inhaling. The measurement will need to be done twice, once using a 6' hose and again using the longer length hose.

I've found that connecting a short hose (18") to the main hose with a
straight swivel connector will keep the hose flatter than just a longer hose.

SNORENOMORE2:

Bearded_One is correct! On cpap.com web-site it states anything 10' or shorter is OK. I use a 10' hose and have never had a probem. My machine has a setting for this size hose (10') or for a standard hose (6'). When I had the Remstar Auto I also used the 10' with NO problem at all! I also do as oldgearhead does and attach an 18" hose to an 8' hose and it does work well and stay flatter as an alternative to the 10' hose.

Hope this helps,

Gee, I've often heard that size does not matter! So sorry, I just couldn't resist!
