Diagnosis - ResMed Middle-East


There are a number of conditions that could be affecting your ability to breathe properly, either while you’re asleep or awake. For example, if you have obesity hypoventilation syndrome (OHS), being overweight places a lot of pressure on the muscles around your lower airway, making it difficult for you to take in enough air. If you have a restrictive lung disease, the muscles and nerves used during breathing are affected, making it difficult to breathe properly on your own.

Generally, if your inability to breathe properly is part of a broader condition, then you will be diagnosed as part of the broader condition. Your doctor or care provider will determine the best diagnosis method for your condition and let you know the next steps to getting treated.

Sleep studies

If your inability to breathe at night is causing you to have apneas (you stop breathing while you’re asleep), your care provider might request that you get a sleep study. Sleep studies are used to assess whether or not you have sleep apnea, and if so, how severe it is. You can do a sleep study in a sleep clinic or in the comfort of your own home.

Blood Gas Analysis

The correct way to diagnose a respiratory insufficiency is via a blood gas analysis. A blood sample will be collected by your physician to determine your O2 and CO2 levels.

Transcutaneous CO2 measurement

If you already are using CPAP for treating your OSA, transcutaneous CO2 measurement can easily identify a respiratory insufficiency while you are sleeping.
