What is a CPAP and how can it change your life?

A few years ago, I first heard the term CPAP. At first, it sounded like another one of those medical acronyms that sounds complicated, but in reality, it's not that complicated and its mechanism is quite simple.

CPAP (Continuous Positive Airway Pressure) is a device that, believe it or not, can greatly improve the quality of life of people with sleep apnea, a condition that causes interruptions in breathing during the night. Today, these devices are practically indispensable for those who need them, as they make it possible to compensate for or eliminate the serious consequences of sleep apnea caused by inefficient rest.

Let's go a little deeper to understand how it works and what types exist, but first, let's talk about sleep apnea, very briefly.

What is sleep apnea?

Sleep apnea is a common disorder in which breathing is repeatedly interrupted during sleep. These breathing pauses, known as apneas, can last from a few seconds to minutes, and occur several times per hour.

As a result, the affected person often wakes up briefly to resume breathing, although they are often unaware of these interruptions. This interferes with deep, restful sleep, impacting the quality of the night's rest. The main causes of sleep apnea depend on its type.

• In obstructive sleep apnea (OSA), the most common type, the upper airway becomes blocked or collapsed during sleep, usually due to excessive relaxation of the throat muscles. Factors such as being overweight, neck anatomy, enlarged tonsils, or alcohol consumption can aggravate this condition.
• In central sleep apnea, the brain does not send the appropriate signals to the muscles that control breathing, which is rarer and is usually related to neurological or heart disease.

The consequences of sleep apnea go beyond daytime fatigue. People with the disorder have a higher risk of developing high blood pressure, heart disease, heart attacks or strokes due to the fluctuations in oxygen that occur during apneas. In addition, repeated episodes of lack of deep sleep affect concentration, memory and mood, which can lead to problems at work or in personal life.

In severe cases, untreated sleep apnea can be life-threatening due to increased cardiovascular risks, making it a serious disorder that should be treated by a medical specialist.

How does a CPAP work?

The idea behind a CPAP is pretty simple. What it does is keep your airways open by applying continuous air pressure through a mask that fits over your nose or mouth. The pressure prevents the muscles in your throat from relaxing too much and blocking the passage of air while you sleep.

It's that simple, and yet so crucial to avoiding those annoying (and dangerous) middle-of-the-night wake-ups. It's like having a personal fan dedicated to making sure you don't run out of air when you need it most.

Types of CPAP, brands and prices

Over time, different versions of CPAP have appeared, adapting to the needs of each patient:

• Fixed CPAP: This is the most basic. It provides a constant pressure throughout the night.
• Automatic CPAP (APAP): This type adjusts the pressure automatically depending on the person's needs at any given time.
• BiPAP: Although similar to CPAP, BiPAP (Bilevel Positive Airway Pressure) allows for two levels of pressure: one for inhalation and one for exhalation. This type is ideal for people with more severe breathing problems.

If you've ever looked for a CPAP, you've probably come across some of the most well-known brands:

• ResMed: This is one of the most popular brands and offers a wide range of devices. Their models are usually compact and fairly quiet.
• Philips Respironics: This company is also a benchmark in the world of CPAP. Their devices are usually easy to use and have good durability.
• Fisher & Paykel: Based in New Zealand, known for the comfort of its masks and advanced humidification technology.

The price of a CPAP can vary greatly depending on the type of device and the features you are looking for. The most basic models usually start at around 300 euros, while more advanced models, such as APAP or BiPAP, can easily exceed 1,000 euros. Added to this is the cost of masks and other accessories, which often need to be replaced periodically.

When are they indicated?

The use of a CPAP is especially indicated in cases of obstructive sleep apnea. This type of apnea is characterized by collapses in the airways, making it difficult to breathe during sleep. CPAP not only improves sleep quality, but can also prevent complications such as hypertension, heart problems, and strokes. That said, it is not a magic solution. A proper medical diagnosis and following the specialist's instructions are necessary both to choose the type and to make complementary decisions on how to improve your general health.

Is there any risk in using these devices?

While CPAPs are safe and effective for most people, they are not without their drawbacks. Some users experience nose or throat discomfort, dryness, and in rarer cases, claustrophobia when wearing the mask.

Problems can also arise if the air pressure is set incorrectly or if you have certain health conditions, such as heart failure or severe lung problems.

Curiosities about CPAP

Now, to add a lighter touch, here are some curiosities:

• CPAP was invented by Dr. Colin Sullivan in 1981 in an attempt to treat his own sleep apnea in a non-invasive way. This first prototype was a homemade construction made from common materials. It used a standard air pump from a vacuum cleaner, a plastic tube, and a mask that he improvised from what he had on hand. The invention worked so well that it was soon refined and produced for clinical use. So, like many other great innovations, CPAP was born in a garage.
• Sleep apnea is a common disorder among aviation pilots due to constant schedule changes and stress, which affects their rest. By improving the quality of their sleep with CPAP, they can stay alert and safe when on duty. In fact, many airlines allow their pilots to wear CPAP devices during their travels to ensure they get adequate sleep.
• CPAPs not only help those suffering from sleep apnea, but there are also cases of professional athletes using them to improve their performance. Adequate sleep is key to physical recovery, and many athletes find CPAP a valuable tool to maximize their rest. Some reports mention that elite athletes such as NFL football players use CPAP to ensure their night's rest is as restful as possible.
• Sleeping in space isn't as easy as it sounds. The lack of gravity causes the body to react in strange ways, and the airflow on the International Space Station is different than on Earth. Although sleep apnea is not common in space because of the changes in gravity, experiments have been done using CPAP on missions to evaluate whether it could help with apnea in future long-term space exploration situations.
• CPAPs have come a long way since the early home models. Today, there are smart devices that connect to your home Wi-Fi and send reports directly to your doctor. These CPAPs collect data while you sleep, such as the number of apnea events, the quality of your sleep, and how the machine is being used. Some even offer mobile apps so you can monitor your own progress.
