What is Obstructive Sleep Apnea?

The partial or complete closure of a patient’s airway during sleep is known as Obstructive Sleep Apnea (OSA). Apnea is Latin for “without breath”. The body responds to this lack of oxygen by arousing, or waking from sleep sometimes in a violent fashion. This cycle leads to the patient being unable to get the needed quantity of restful sleep and results in:

•Irritability and Mood Swings

•Daytime Fatigue

•Difficulty Focusing/Memory Loss

Untreated Obstructive Sleep Apnea is potentially fatal and has been shown to lead to the following serious health conditions:


•Heart Attacks


•High Blood Pressure

What is a CPAP machine?

CPAP stands for Continuous Positive Airway Pressure. CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. This eliminates or reduces sleep disordered breathing events (sleep apnea) and allows you to get a restful sleep. CPAP therapy is traditionally provided through a nasal mask that seals around the nose. However, more innovative, comfortable and better sealing options are beginning to emerge.

Which CPAP machine is for me?

Since your CPAP machine requires a prescription; it is best determined by your physician as to which device will work best for you. We encourage you to ask many questions or describe your typical sleeping situation, this may assist your physician in the decision making process. Things to consider are: type of usage, do you travel; do you need humidification, weight of the machine, size of the machine, noise level, etc.

How do I travel with my CPAP machine?

Traveling with your CPAP can sometimes be a hassle. However, with proper preparation, it can be very easy. If you are flying with your CPAP, you can bring your CPAP machine on the airplane with you and it will not count as one of your carry-on items. Never check your CPAP machine because through normal luggage handling procedures it can easily be broken. You may want to call ahead and find out your airline's procedures for carrying your CPAP machine on the airplane to prevent any delays through security. We have learned that many airlines will not let you use your CPAP machine during the flight because it is not a life-sustaining device. You may want to contact your airline to see if you can make special arrangements If you are driving across country with your CPAP or are camping, you can still use your machine (depending on the make and model). If your machine has the ability to run off of 12V (check your owner’s manual) then you will be able to run your machine off of either a battery, or plug it into the cigarette lighter adapter in your car / RV if you purchase the proper cables.

What is an Auto CPAP machine?

An Auto CPAP machine is a machine that uses two pressure settings; a high setting and a low setting. The machine starts at the lower setting and through the course of the night it senses when you are having sleep disordered breathing. It then begins to slowly raise the pressure toward the set high pressure. Once the apnea is eliminated it will stay at that pressure for a period of time and then slowly begin to decrease back toward the lower pressure. If another apnea occurs in the meantime, it will then begin to increase, so on and so forth. In this way, the machine automatically figures out the best pressure for you to be sleeping at for that particular night. This is a nice feature because your best therapy pressure is not always the same. It greatly depends on your daily activities and your personal habits.

Back to Top

What is a Bi-PAP or Bi-Level machine?

A Bi-PAP or Bi-Level machine uses two separate pressure settings for your therapy: An inspiratory pressure and an expiratory pressure. When you inhale, the therapy is delivered at the set inspiratory pressure, and then when you exhale, the pressure is delivered at the set expiratory pressure. The inspiratory pressure is always greater than the expiratory pressure. This type of machine is usually used for people who cannot tolerate a normal CPAP machine or for people who have other conditions along with their sleep apnea.

I feel air leaking around my CPAP mask when I put it on; how do I fix this or is it normal?

CPAP masks are designed with an intentional leak so that during exhalation your CO2 is "blown off" and you are not retaining it. This blowing air can usually be felt from the exhalation port on your mask. If the air leaking from you CPAP mask is around the cushion seal it could be a number of things.

1.) Has the CPAP mask leak just developed or has it been leaking since you first got the CPAP mask? If it happened over a period of time, it's most likely oil and dirt build up on the cushion from lack of proper CPAP mask cleaning or maintenance OR the CPAP mask has been used for a longer period and needs replaced (remember, these masks really only have a shelf life of 3 months to a year.

2.) If the mask has leaked from the begining, it's most likely that you have not been properly fit for the right CPAP mask size or your facial structure dictates that you need a different style mask.

3.) You have facial hair that is limiting the CPAP mask seal; in which case you may want to explore a different mask style.

4.) The CPAP mask cushion has seperated from the CPAP mask frame. Examine the mask and make sure it is properly put together.

I am new to CPAP and I am having a hard time coping with CPAP.

This is understandable for most people new to CPAP therapy. Lets face it, more than likely you have gone most of your life not sleeping with a mask on your face or pressurized air blowing into your nasal passage. CPAP does take some getting used to and the first few weeks are the toughest. Some people adjust to right away while others need an elevated level follow up, direction and support during this transition period.

CPAP machines have ramp features to assist with the anxious feeeling of breathing on the CPAP machine while you are awake. Adjust your ramp time accordingly and gradually reduce it when you become more compliant with CPAP. If you can only use the CPAP machine for a few hours the first night, thats OK, try to use it a little longer the next night and so on until you can sleep the entire night with it.

Many first time users will pull the mask off during the night and not even realize that they did it. This is typical during intial CPAP use and should subside over time.

Try wearing the CPAP mask and using the CPAP machine while watching TV or reading before bed time, this should help reduce that anxiety you may feel when you first go to bed and put the CPAP mask on. If all else fails, contact your CPAP provider and speak to a specialist about specific issues.

I hate CPAP. I hate wearing the CPAP mask and I hate the CPAP machine!

CPAP therapy does take patience and determination at first to make that break through to CPAP compliance. There are other alternatives to CPAP such as surgery, oral appliances, or based on your degree (i.e mild, moderate or severe sleep apnea)a diet and exercise plan. These alternatives should first be discussed with your treating physician prior to use. CPAP has been the only 100% proven effective treatment for sleep apnea but others might be a candidate for alternative treatment. You should consult your physician prior to any decision for therapy selection.
