sunset oxygen adapter for cpap

Key Features

  • Inline oxygen bleed‑in adapter for adding supplemental oxygen to CPAP or BiPAP therapy without changing mask or machine.
  • Standard 22 mm connections with 6 mm barbed rotating stem, compatible with most CPAP/BiPAP devices, masks, and oxygen tubing.
  • Works with standard or heated tubing, placed between machine and hose for standard tubing or between hose and mask when using heated hoses.
  • Compact, lightweight design that sits neatly in the circuit and helps minimize added hose weight or pull.
  • Many versions include a cap for the oxygen port, allowing you to seal it off easily when you are not using supplemental oxygen.
Description

The Sunset Healthcare RES019 Oxygen Enrichment Adapter is a simple inline oxygen “bleed‑in” connector that lets you add supplemental oxygen to your CPAP or BiPAP setup without changing masks or machines. It uses standard 22 mm connections and a 6 mm barbed rotating stem, so it drops neatly into your circuit and accepts common oxygen supply tubing from a concentrator or tank.

This adapter installs between your CPAP/BiPAP machine and tubing or between the tubing and mask, depending on whether you use standard or heated hoses. Once in place, oxygen from your concentrator flows through the small side port into the main CPAP airflow, allowing your prescribed oxygen to blend with your sleep therapy.

The RES019 is lightweight and low‑profile, designed to keep your setup comfortable and to avoid adding noticeable drag to the hose. A rotating stem at the oxygen port helps manage tubing direction, and many versions include a cap so you can close the O₂ port when not in use instead of removing the entire adapter. It is intended for patients who have been prescribed both CPAP/BiPAP and supplemental oxygen and need a straightforward way to combine them.

Product questions & answers

What does the Sunset oxygen enrichment adapter do?
The RES019 Oxygen Enrichment Adapter is an inline connector that lets you “bleed in” supplemental oxygen from a concentrator or tank into your CPAP/BiPAP airflow. It sits in the breathing circuit and uses a small side port to mix oxygen into the pressurized air going to your mask.

Where does this adapter go in my CPAP or BiPAP setup?
For standard tubing, the adapter typically goes between the CPAP/BiPAP machine and the hose. If you use heated tubing, many setups place the adapter between the hose and the mask so the heated hose can still attach directly to the machine. Always follow your clinician’s or equipment provider’s instructions for your specific system.

Is this adapter compatible with my machine, mask, and oxygen tubing?
The RES019 uses standard 22 mm connections and a 5–7 mm barbed oxygen port, so it is compatible with most CPAP and BiPAP machines, standard or heated hoses, and nasal, nasal‑pillow, or full‑face masks that use standard fittings. The barbed stem accepts common oxygen supply tubing from most concentrators and tanks.

Does this adapter change my CPAP pressure or replace my oxygen prescription?
No. The adapter does not generate oxygen or change your CPAP/BiPAP pressure settings; it simply provides a connection point to blend in oxygen from an external source. You must still use the oxygen flow rate prescribed by your clinician, and any pressure changes should only be made under medical guidance.

How do I know what oxygen flow rate to use with this adapter?
Always follow your doctor’s prescription for oxygen flow rate. The adapter itself does not limit or set flow; it only provides a bleed‑in port. Your oxygen source (concentrator or tank) should be set to the prescribed liters per minute, and your CPAP/BiPAP device should remain at the settings ordered by your clinician.

Can I leave the adapter in place when I’m not using oxygen?
Many versions of the RES019 include a cap for the oxygen port, allowing you to close the side port when you are not using supplemental oxygen so you don’t have to remove the adapter from the circuit. If your version does not include a cap, your provider may recommend removing the adapter when oxygen is not needed.
