A CPAP machine is used to provide therapy which is effective in treating obstructive sleep apnea. In CPAP therapy, air that is pressurized is blown down your throat to keep your airway open when you sleep.
When suffering from sleep apnea, your airway gets blocked when the tissues at the back of your throat collapse. As a result, your breathing halts for a few seconds and you have to wake up to take in a breath of air. You however do not have to endure interruptions in your sleep when using CPAP therapy. You can buy CPAP machines online where you can compare products from a wide variety of vendors.
How CPAP Works
In order to undergo CPAP therapy, you not only require a machine but you will also have to purchase a mask. When you purchase CPAP masks or buy CPAP machines online, the cost is normally lower than when you buy from a local vendor. The CPAP machine is made up of a pump that sucks in air from the room. The air passes through a filter and is then pressurized and transmitted through a tube to the mask.
Depending on the mask that you have, you can wear it over your nose and mouth or over your nose only. You will then be able to breathe in the pressurized air which will keep your airway open and allow you to breathe without a problem. You can decide to use a fixed pressure or an automatic pressure machine. There are also a variety of masks including the full face mask, the nasal mask and the nasal pillow.
How Should CPAP Feel?
If you are using a fixed pressure machine, you may find it difficult to adjust to the pressure. You can therefore use a machine that has a ramp feature. This feature enables the machine to deliver the pressure to you gradually. When you switch on the machine, the air is transmitted at a low pressure which is gradually increased until the required level is attained. This will allow you to comfortably adjust to the air pressure of the machine.
An automatic machine automatically adjusts the pressure depending on your breathing needs. It increases the pressure when your airway blocks and reduces it when the airway opens and you are breathing normally once more. This machine is comfortable to use since the pressure transmitted at any one time is the exact amount of pressure that you require.
How Should CPAP Mask Fit?
Getting the right design and size of a mask is crucial if your CPAP therapy is going to be effective. A CPAP mask should fit just right so that it gives you a good seal to ensure that the pressurized air does not leak during therapy. Air leakage interferes greatly with the effectiveness of the therapy.
If a mask does not fit right, you should not try to tighten it too much since it will create spaces through which the air can leak. You can buy CPAP machines online together with a mask that has various sizes of cushions so that you can use the one that fits properly. It is important to keep your prescription safely since many CPAP vendors will request you for it.
