Answers
What are current treatments for sleep apnea?
Treatment for sleep apnea depends on the type and severity of the condition. Treatment options may include positive airway pressure therapy such as CPAP or APAP, oral appliances, positional therapy, lifestyle changes, and other treatments recommended by a qualified healthcare professional.
CPAP and APAP therapy are commonly used treatments for obstructive sleep apnea.
Does sleep apnea get worse with age?
Sleep apnea can become more common or more pronounced as a person gets older. However, age is only one of many factors that can affect sleep apnea.
If you notice changes in your symptoms or CPAP therapy results, discuss them with your healthcare provider.
Can untreated sleep apnea lead to serious health risks?
Untreated sleep apnea can affect sleep quality and overall health and may be associated with other health conditions.
If you believe you may have sleep apnea, speak with a qualified healthcare professional about appropriate testing and treatment.
What are common symptoms of sleep apnea?
Common symptoms can include loud snoring, pauses in breathing during sleep, gasping or choking during sleep, excessive daytime sleepiness, morning headaches, and difficulty concentrating.
Symptoms vary between individuals. A healthcare professional can determine whether a sleep evaluation is appropriate.
What is obstructive sleep apnea?
Obstructive sleep apnea occurs when the upper airway repeatedly becomes partially or completely blocked during sleep. These interruptions can reduce airflow and disturb normal sleep.
What is a CPAP machine?
A CPAP machine delivers a continuous flow of pressurized air through a mask to help keep the airway open during sleep. CPAP therapy is commonly prescribed for people with obstructive sleep apnea.
What is the difference between CPAP and APAP?
A traditional CPAP machine generally delivers therapy at a prescribed fixed pressure. An APAP, or Auto CPAP, can automatically adjust pressure within a prescribed range based on detected breathing patterns.
Your healthcare provider should determine which therapy and pressure settings are appropriate for you.
How do I choose a CPAP machine?
The right machine depends on your prescription, therapy requirements, desired features, portability needs, and compatibility with your existing equipment.
- Fixed CPAP versus Auto CPAP
- Humidification options
- Therapy data and monitoring
- Machine size and portability
- Comfort features
- Compatibility with your preferred mask
What is the difference between the ResMed AirSense 10 and AirSense 11?
The AirSense 11 is the newer generation of ResMed's popular CPAP platform. The machines differ in design, features, accessories, and replacement components.
When replacing a machine or purchasing accessories, make sure the product is compatible with your specific model.
Can I travel with my CPAP machine?
Yes. Many CPAP machines are designed to be portable enough for travel. Dedicated travel CPAP machines are also available for people who prefer a smaller and lighter setup.
What types of CPAP masks are available?
The three common CPAP mask styles are full face masks, nasal masks, and nasal pillow masks.
- Full Face Masks: Cover the nose and mouth.
- Nasal Masks: Cover the nose.
- Nasal Pillow Masks: Use small cushions that rest at the nostrils.
What is the best CPAP mask for a mouth breather?
People who breathe through their mouth during sleep may prefer a full face CPAP mask because it provides therapy through both the nose and mouth.
However, mouth breathing can have several possible causes. Persistent dry mouth, leaks, or difficulty using a mask should be discussed with a healthcare provider.
How do I choose the correct CPAP mask size?
CPAP masks are available in different sizes, and sizing systems vary by manufacturer and mask model.
Always use the manufacturer's sizing guide for the specific mask you are purchasing. An improperly sized mask can contribute to discomfort and air leaks.
Why is my CPAP mask leaking?
Common causes of CPAP mask leaks include an incorrect mask size, incorrect headgear adjustment, a worn cushion, mask movement during sleep, or incorrect positioning of the cushion.
Tightening the mask excessively is not always the solution. Over-tightening can sometimes make the seal less effective.
How can I stop my CPAP mask from leaking?
Start by making sure the mask is correctly sized and positioned. Adjust the headgear according to the manufacturer's instructions and check the cushion for signs of wear.
If the problem continues, a different mask style or size may provide a better fit.
How often should I replace my CPAP mask cushion?
Replacement schedules vary depending on the manufacturer, frequency of use, condition of the cushion, and your insurance or DME replacement schedule.
Replace the cushion when it becomes worn, damaged, stretched, or no longer maintains a proper seal.
What CPAP supplies need to be replaced?
Common replacement CPAP supplies include mask cushions, nasal pillows, mask headgear, CPAP tubing, air filters, water chambers, and complete masks.
Can I use a different CPAP mask with my CPAP machine?
Many CPAP masks can be used with different CPAP machines because standard CPAP tubing connections are commonly used. However, always verify compatibility with your particular equipment before purchasing.
How often should I replace my CPAP filter?
Follow the replacement recommendations for your specific CPAP machine and filter. Inspect the filter regularly and replace it when it becomes dirty, damaged, or according to the manufacturer's recommendations.
How often should I replace CPAP tubing?
Inspect your tubing regularly for cracks, damage, discoloration, or deterioration. Replace tubing when it is damaged or no longer in good condition.
Why is my CPAP AHI still high?
Your CPAP machine may display an estimated AHI based on events detected during therapy. A higher-than-expected AHI can have several possible causes, including mask leaks, pressure settings, sleep position, or other factors.
Do not change prescribed pressure settings on your own. If your AHI remains consistently elevated, discuss your therapy data with your healthcare provider.
Why does my CPAP pressure change during the night?
If you are using an Auto CPAP or APAP machine, the pressure may automatically increase or decrease within the prescribed range in response to detected breathing patterns.
If you notice unexpected pressure changes or have concerns about your therapy, review the machine settings and therapy data with your healthcare provider.
Why do I have a dry mouth when using CPAP?
Dry mouth can occur for several reasons, including mouth breathing, air leaks, humidification settings, or other factors.
If you use a nasal mask or nasal pillows and frequently breathe through your mouth, discuss the issue with your healthcare provider.
What is CPAP rainout?
CPAP rainout occurs when moisture from the humidifier condenses inside the tubing or mask. It can result in water droplets, gurgling sounds, or water reaching the mask.
Depending on your equipment, possible solutions may include adjusting humidification settings, using compatible heated tubing, or adjusting the temperature of the room.
Why am I still tired after using my CPAP?
Feeling tired despite using CPAP can have multiple possible causes. Therapy effectiveness, mask leaks, sleep duration, sleep quality, other medical conditions, medications, and other factors may contribute.
Review your therapy data and concerns with your healthcare provider rather than changing your treatment settings yourself.
