Buying Guide: CPAP & BiPAP Devices
If your doctor has recently told you that you need a “sleep apnea device” or if your loud snoring is affecting your daily life, don’t worry. The world of these machines may seem overwhelming at first, but in reality, things are
This guide was created to help you understand exactly what you need to sleep properly, without confusing medical terms.
The most important step before you start!
The choice of device type and pressure settings is made only by your Pulmonologist, after you first undergo a special test called a “Sleep Study”. The doctor will give you a written prescription that will state exactly what you need.
What are the types of devices?
In the market, you will see three main device names. Let’s see what each one does in simple terms:
CPAP (Constant Pressure): It sends you a steady, continuous, and gentle flow of air all night through a tube and a mask. This air works like an “invisible pillow” that keeps your throat open so your breathing doesn’t stop. It is the most classic solution.
APAP (Automatic CPAP): This is the most popular and modern choice today! Instead of delivering the same pressure all night, the automatic CPAP “understands” when you change sides or when you start snoring and adjusts the air pressure on its own, at that exact second. It offers much more comfortable sleep because it doesn’t pressure you unnecessarily when you are breathing calmly.
BiPAP (Two Pressure Levels): These devices are more advanced and do something smart: they deliver strong pressure when you inhale (so air enters easily) and immediately lower the pressure when you exhale (so you don’t struggle to breathe out). They are preferred for more specific cases (such as central sleep apnea, people with COPD, or those who have difficulty getting used to the counter-pressure of a simple CPAP).
The Mask: 50% of the success!
The device may be the best in the world, but if the mask doesn’t suit you, you won’t be able to sleep.
There are 2 basic types depending on how you sleep:
Nasal Mask (Nasal): Covers your entire nose. It is the most common choice. It is ideal if you sleep with your mouth closed and want stability.
Oronasal Mask (Full Face): Covers both the nose and the mouth. It is absolutely necessary if you often have a blocked nose, if you suffer from allergies, or if you unconsciously open your mouth when you sleep.
What “extra” features should you look for for more comfort?
When comparing models, focus on these 3 things that will make your life much easier:
The Humidifier: It is a small container that holds water and warms the air before it reaches you. We definitely recommend it! Without a humidifier, the continuous airflow can dry out your nose and throat, causing congestion or irritation, especially in winter.
Smart Features: Modern models (such as the ResMed AirSense 11 or Lowenstein Prisma series) have Wi-Fi or Bluetooth and connect to an app on your phone. That way, every morning you can see your sleep “score” (whether you moved the mask, whether you had leaks, etc.). The best part? Your doctor can see this information from their computer and change your device settings remotely, without you having to go to the clinic!
Portability (Travel Devices): If you travel often for work or vacation, there are special, very small devices that are palm-sized (like the ResMed AirMini). They fit easily in a bag so you never miss your therapy.
