Did you know?

Nearly 1 billion people worldwide have sleep apnea1

What is sleep apnea?

Sleep apnea is a disorder in which the muscles in the throat relax to the point of collapse, restricting airflow. This causes breathing to become shallow and even stop for seconds or minutes at a time, depriving the body and brain of oxygen. The lack of deep sleep can cause significant fatigue and elevate the risk for serious health problems. Most people with sleep apnea are unaware they have it.

Apnea events explained in 3 easy steps

1. Air stops flowing

An apnea event is when air stops flowing to your lungs for ten seconds or longer, meaning you stop breathing.

2. Brain sends a signal

Your brain sends a signal to your body to wake up and take a breath. You take a breath and fall back to sleep.

3. Cycle repeats

These apnea events can occur hundreds of times a night and many people with sleep apnea don’t know it’s happening.

Getting ready to start sleep apnea therapy

When you first learn you have sleep apnea and are prescribed CPAP therapy, you may feel overwhelmed. That’s normal! But it’s also important not to become discouraged, and to start learning the basics about what to do next and what to expect.

Step 1

Understand your sleep test results

After your sleep test, you and your doctor will go over your results together and discuss your diagnosis. If you have sleep apnea, you will discuss the severity level, possible health effects and treatment options. Here are some common medical terms that you may see in your results.

This is when you stop breathing during sleep. For obstructive sleep apnea, it’s when the entire airway is blocked, preventing air from entering the lungs.

A reduction in airflow by 30% or greater associated with a similar reduction in the movement of your chest and stomach, as well as a 3% (4% for Medicare guidelines) or greater fall in the blood oxygen level2.

The severity of sleep apnea can be measured by the average number of times per hour someone had an apnea or hypopnea while they slept.

Measures the number of times per hour that the level of oxygen in the blood drops below a normal level.

This is the average number of respiratory disturbances – including apneas, hypopneas and other respiratory events – per hour of sleep.

Step 2

Your CPAP equipment: how it works

CPAP equipment is used to treat sleep apnea. There are 4 products that all work together to deliver your therapy: the machine, a mask, tubing and Resmed myAir app. The CPAP machine creates the airflow that is pushed through the tubing, to the mask, and into your lungs.

Step 4

Your insurance, compliance and therapy data: what you should know

Many insurance providers require proof of a 90-day therapy compliance period in order to cover your equipment. This means showing that you can stay on therapy for a full 90-day period.

Your CPAP machine automatically transmits your nightly data to your equipment provider and your doctor so they can monitor your compliance. If your therapy usage and data is not consistent with the required amount of time, your insurance provider may not cover the cost of your CPAP equipment.
