We all know who the big bad wolf of the sleep disorder world is: sleep apnea. We’ve heard of the horror stories of how this unrelenting wolf keeps its victims from having a full night’s rest. However, like any good story, this one has a hero to save the day: continuous positive airway pressure, but you can call him CPAP for short. This is the best, non-surgical treatment for sleep apnea. Its method of respiratory ventilation is a fairly simple concept. The patient wears a snug mask that avoids any air leakage. A tube that connects the mask to the small and portable appliance delivers heated and humidified air through a nasal or face-mask under pressure. This air pressure then keeps the tissues at the back of the throat open during sleep to avoid any airway blockage that results in OSA.
The CPAP appliance can be connected to nasal pillows, nasal masks, or full-face masks to ensure that the patient feels as comfortable as possible. CPAP is not only concerned with giving patients a full night’s rest, but comfort is also important. It is important to start with the lowest possible air pressure when using CPAP. This is determined by a process called titration. Using the lowest possible air pressure to get the job done ensures that the patient will be that much more likely not to feel like they’re using CPAP at all.
There are many different kinds of CPAP therapy. There’s bi-level positive airway pressure (BiPAP) and auto-titrating continuous positive airway pressure. Think of it as the Justice League of sleep apnea treatment. BiPAP delivers a higher pressure of air during inspiration and a lower pressure during expiration. This difference between CPAP and BiPAP allows the patient to feel as if they’re not breathing out against such a high pressure. As one can imagine, this would be more comfortable for most patients. Auto-titrating CPAP is considered a “smart” CPAP machine because it makes pressure adjustments by itself throughout the night. The goal of this machine is to deliver the lowest possible pressure for each position or sleep level the patient is at. This variety of CPAP therapy just goes to show that patient comfort is taken seriously.
However, just like any good superhero, CPAP does have its downfall. First of all, this treatment is not easy to use. Only forty-five percent of patients use it for more than four hours a night. Twenty-five to fifty percent of patients stop using CPAP altogether. Those with claustrophobia have a hard time adjusting to sleeping with a mask on their face throughout most of the night. It’s crucial to use CPAP as much as possible for the first few months so that the patient can become accustomed to it that much quicker.
If used properly and accordingly, CPAP can be very effective. CPAP therapy can decrease the number of apneas and/or hypopneas a patient experiences every night. As a result, sleepiness is less likely the next day, cognitive functioning on tests improves, driving on driving simulation tests improves, and the number of accidents in the real world is decreased. Proper use of CPAP reduces hospitalization for cardiac and pulmonary causes. CPAP therapy can reduce the risks of the many conditions related to OSA, such as ischemic heart disease, abnormal heart rhythms, stroke, hypertension, and insulin dependence.
While there are other treatment options for sleep apnea, CPAP is the best out there. Why? Well, dental appliances are not only invasive, but they must be worn every night. Surgery seems like a more permanent solution. However, it’s extremely painful, expensive, and there is no guarantee for success. At the moment, CPAP is the only treatment option that isn’t as invasive as dental appliances, and is not as excruciatingly painful and expensive as surgery.
When it comes to the big bad wolf known as sleep apnea, here comes CPAP to the rescue.
