9 Causes of a Noisy ResMed CPAP Machine and How to Fix Them | too much air (2023)

RespectivelyCenters for Disease Control and Prevention, Sleep apnea is a common sleep disorder that can be treatedCPAPTherapy. ResMed devices are one of the most popular devices for CPAP therapy; However, during use, the machine may make noises that need to be diagnosed and repaired.

A ResMed CPAP is noisy due to condensation from the CPAP, a clogged filter, humidifier setting, temperature, or air leaks. Other reasons are the position of the CPAP, the air pressure and the temperature of the hose that is too low.

This article provides the 9 reasons why your ResMed CPAP machine might be making noise, how to diagnose each cause, and how to fix the problem.


1. Air leak

Your ResMed CPAP machine is most likely making noise due to air leaks.

There is a point of contact, or seal, between the CPAP machine and your face, and if it is not attached correctly, it will leak. Air can also leak if the tubing is not properly connected to the mask or device.

To diagnose:

  • Waking up with dry eyes.
  • If the water tank is cracked or cloudy.
  • Waking up with a dry or stuffy nose.
  • A gurgling sound on inhalation.
  • leaks
  • Holes, tears and tears in the breathing tube.
  • straps on the hose.

How to fix it:

  • Make sure the tubing is properly connected to your mask and device.
  • Run your hands along the length of the CPAP hose to ensure there are no leaks.
  • Flatten your CPAP hose before going to bed to ensure there are no kinks or kinks that could cause a pressure buildup.
  • Purchase a hose cap.
  • Disconnect and reconnect the hose at both ends to see if you can restore the seal and eliminate the hiss.

2nd digit

A ResMed CPAP machine can cause excessive noise due to its location.

If your CPAP is right next to your head on the nightstand, you may not be able to sleep because of the noise.

If your ResMed CPAP machine vibrates or hums, you can muffle the noise by placing it on a soft surface such as a towel or foam pad, but make sure the vents are not blocked and it is on a flat surface.

Do not place your device on the matif you don't want to block the vents.

CPAP hoses come in a variety of lengths to allow you to position your device in the most comfortable position. Consult your doctor before using any to make sure it is right for you.

To diagnose:

  • accumulation of water in the hose.
  • trouble sleeping

How to correct it:

  • Place it on a soft surface such as a towel or foam pad.
  • Talk to your doctor about where to place the CPAP.
  • Consult the recommendations in the user manual.

3. Cold tube temperature

A common reason for a noisy ResMed CPAP machine is that the hose temperature is too low.

When falling asleep, some people find it easier to breathe fresh air. However, if the temperature in the probe is very low, your ResMed can always go up.

In fact, the noise is caused by the temperature difference between the pipe and the room. Due to the temperature difference, if moisture enters the unheated pipe, the moisture may condense.

For CPAP therapy to work properly, the temperature and humidity inside the mask and tubing must match the temperature and humidity outside the mask and tubing.

To diagnose:

  • breathe mouth.
  • Waking up with a dry mouth.
  • Tos.
  • Sneeze.
  • Swelling.
  • Headache.

How to fix it:

  • Using a heated humidifier.
  • Adjust the temperature in your bedroom.
  • Using a ResMed self-adjusting CPAP.

4. Clogged filter

A clogged filter is one of the most common causes of a noisy ResMed CPAP machine. The filters in a CPAP capture dust, allergens, and debris to reduce the risk of inhaling particles or contaminants during use.

However, for optimal performance, you should change them regularly. Otherwise, they can become clogged and force your CPAP to work harder and harder to circulate air, which can lead to the noises you're experiencing.

Supervision:ResMed strongly recommends replacing the filters andNOwashed or reused.

Diagnosis of a clogged filter:

  • if there is a layer of dust on top
  • If the filter is clogged or has holes.
  • Check the condition of the filter every month.
  • Schedule regular maintenance or filter change routines.

To change the ResMed CPAP filter:

  • Disconnect the device.
  • Remove the rear air filter cover.
  • Remove and discard the old filter.
  • Insert a new filter into the device with the blue side facing out.
  • Put the cover again.

Supervision:To prevent water and dust from entering the device, make sure the air filter is always in place.

5. Loose mask

A common reason for a noisy ResMed CPAP is a loose mask.

A loose mask is one that does not fit well because it is too big. Regardless of the brand of CPAP, the CPAP machine will make noise if the mask you are wearing is loose. This is especially common when you buy a new goggle without fitting it properly first.

To diagnose:

  • Keep slipping.
  • You notice leaks more often.
  • You snore or experience apnea even when using CPAP.

How to fix it:

  • Always fit the mask before purchasing.
  • Before buying, please make sure that the helmet is not too tight, the size of the mask is correct, and you are satisfied with the type of mask.
  • Tighten the mask straps as tightly as possible without causing discomfort.
  • Get additional CPAP equipment such asCPAP mask insert or padswith cutouts for a better fit.
  • remove the mask andreplace itwith a new one

6. Humidity settings

One of the reasons your ResMed device is noisy is that it is set to the wrong humidity setting. If you have a CPAP machine with a humidifier, your machine will generally work a little harder, adding moisture to the circulating air, especially if it gets hot.

When the water level in the tank is too low, you may hear noise.Incorrect humidifier settingleads to fluctuation of humidity, which produces a distinctive noise.

The pressure of your CPAP machine must be correctly set to avoid these noises.

To diagnose:

  • Discomfort in the mouth, nose and respiratory tract.

How to fix it:

  • Make sure the lid is secure.
  • Use distilled water in your CPAP humidifier to prevent mineral buildup that makes the CPAP stronger.

7. Air pressure

The noise coming from your ResMed CPAP device is most likely due to air pressure. The pressure should not be too high or too low. device selectionAuto ramp settingIt can help if the air pressure seems too high. As a result, it offers a low initial pressure that makes it easier to fall asleep.

Also, with the sleep detection feature, ResMed gradually increases the prescribed pressure once it detects that you have fallen asleep. Expiratory Pressure Relief (EPR) reduces the pressure exerted during expiration, facilitating exhalation against atmospheric pressure.

To diagnose:

  • Noise when inhaling.

How to fix it:

  • Adjust the air pressure correctly. The ideal CPAP pressure for most people is between 6 and 14 cmH2O, with an average of 10 cmH2O.
  • Ask your doctor what the correct air pressure is.

8. Temperature

Temperature is another cause of ResMed noise. If the ambient temperature and the temperature of your CPAP machine are different, noise will occur.

For ResMed automated CPAPs, the HumidAir heated humidifier reaches its optimal temperature of 104°F. The device then maintains this temperature for another ten minutes so that therapy can begin. If therapy is not started within this time period, the CPAP will cool down and blow cool air.

The ResMed device works with or without water. However, if you want to run it without water, you'll need to go into the menu and turn humidification off in the "My Options" menu.

If you use water in your ResMed CPAP device, make sure it is distilled water.

To diagnose:

  • regeneration
  • Clogged hose.
  • The hose looks cloudy.
  • sore throat.
  • Nasal congestion.

How to fix it:

  • adjust temperatures.
  • Adjust the humidifier settings as recommended by your doctor.

9. Feedback

CPAP rainout is a very common reason for a noisy ResMed CPAP device.

Andhot airAs it cools in your hose and comes in contact with the mask like water, CPAP condensation occurs, leaving your face moist. You will hear noises when condensation hits the tubing and mask.


  • Waking up with a wet face.
  • Gorgoling sin tubo.

How to fix it:

  • Use a ResMed automated CPAP device, such as the ResMed AirSense 10.
  • Make sure the CPAP machine and the mask are not level.
  • Lower the pressure on your CPAP machine to the same level as the pressure on your mask.
  • Use a heated hose or insulate the CPAP hose with a cloth.
  • Wearing a thin jacket.
  • Roll up the CPAP hose to ensure an even supply of warm air.
  • Set your CPAP to a suitable temperature level.
  • Make changes to the temperature in your bedroom.
  • Make adjustments to the humidifier settings.

More details about ResMed's leaking CPAP devices are available.available here.

A ResMed CPAP machine beeps because it has detected a leak. The beep is a notification that you need to adjust your mask to minimize leaks. When the mask position is corrected, the beep stops.

To reset your ResMed CPAP device, access the Clinical Menu by navigating to the My Options menu and holding down the Home and Rotate buttons simultaneously for approximately 5 seconds. The settings can be adjusted as desired.

You can also turn the machine off, back on, and go back to sleep with the machine at low starting pressure.

A ResMed CPAP machine will not turn on if there is a problem with the power cord, if the outlet is faulty, or if the CPAP machine is faulty.

However, it is more likely that the ResMed CPAP is inactive or the power supply has been interrupted. Especially when the ResMed CPAP won't turn on and the screen is blank.
