In years gone by, the answer to this question would have been "yes", but today not all
hoses are the same and some machines use different hose types. All CPAP hoses / tubings serve the same function: directing the air stream from the machine to the mask.
Historically, a standard CPAP hose is six feet long, has an internal diameter of 19mm and a connector cuff with an internal diameter of 22mm. Today some hoses are 6 feet long, others are 4 foot long, 8 foot long and 10 foot long. Some hoses have an internal diameter of 19mm (standard) and others have an internal diameter of 15mm (thin or slim style). To use a slim 15mm hose, the machine must have a menu option setting to accept the narrower diameter of a 15mm hose and still deliver the prescribed pressure to the mask to ensure effective therapy.
All hoses have a 22mm connection cuff and fit on all CPAP masks. The connection ports on all
CPAP,
APAP and
BiLevel machines,
humidifiers, and
masks are a standard size, so a standard CPAP hose will fit on all. Some of the very small machines use a
hose adapter between the machine and the 22mm cuff of the hose.
Some manufacturers offer a
heated hose option designed to work only with their machines. To read more about heated hoses see the
"What is a heated CPAP hose?" article included in this FAQ section.
A few auto-titrating CPAPs and BiLevels require a
pressure line sensor to detect breathing patterns and pressure needs. The sensor may be in the form of an adapter with narrow tubing attached or the narrow tubing is threaded inside the six foot hose. In both cases, one end of the narrow tubing is plugged into the machine. Those machines will not operate without the pressure line sensor.
