Apnea monitors help assess whether a person has uninterrupted breathing during sleep. There are various types.

In this article, we explore what sleep apnea monitors do and some options available.

Please note that the statements below are based only on research. No one at Medical News Today, including the writer, has tried these products.

A person might use one of these monitors to track the breathing of an infant or an adult at risk of respiratory failure.

There are different types of monitors, but they all contain sensors that measure aspects of the body during sleep, such as breathing and movement.

Each device also contains a microcomputer that processes the information to determine whether breathing has stopped. If it has, the device sounds an alarm to wake the person or parents or caregivers.

The World Health Organization (WHO) warn that apnea monitors are subject to misreadings. They explain that movement, the person’s heartbeat, and nearby electrical devices can each cause false readings.

Sleep apnea is a common disorder that causes a person to stop breathing repeatedly during sleep.

In adults

A person may not realize that they are experiencing sleep apnea. However, some signs include:

  • snoring
  • gasping for air while sleeping
  • daytime sleepiness
  • dry mouth when waking
  • headaches when waking
  • sexual dysfunction
  • decreased concentration

In infants

Sleep apnea in an infant involves interruptions in breathing of 20 seconds or longer.

However, shorter interruptions accompanied by a slow heart rate, bluish or pale skin, and muscle weakness can also indicate apnea.

A person might try the following smartphone app or separate devices:


This app turns a smartphone into a sleep apnea monitor or tracker. It assesses movement and breathing and generates a sleep score. A person can also use it to track the progress of interruptions in sleep and gain insight into apnea patterns.

A person can download SleepScore for Android or iPhone devices through SleepScore Labs’ website or by searching for the app’s name on their phone.

Anyone who thinks that they have sleep apnea should consult a doctor.

Though it is not necessary, using a tracker ahead of the appointment can help provide the doctor with useful information, such as how often apnea occurs and the effects on sleep.

A sleep apnea monitor can give information about a person’s breathing during sleep. Monitors may track breath rate, blood oxygen levels, and heart rate, for example.

Those designed for infants might also track body temperature and when they have rolled onto their stomachs.

These monitors come in different forms, and cost varies accordingly. It is important to choose a device that suits a person’s needs, including comfort.

Anyone who believes that they experience sleep apnea should contact a doctor.
