Seldom will you hear polysomnogram. Most doctors and patients simple say " sleep test". The polysomnogram is indeed a sleep test. It is considered the gold standard of sleep testing.
There are different levels on polysomnogram testing. A level 1 polysomnogram is the most detailed and thus far the only level I order. The level 1 polysomnogram consist of
- Monitors placed on the scalp to look at brain wave patterns.
- Monitors at the nostrils and mouth to monitor breathing.
- A microphone may be added to listen for snoring.
- The heart is monitored.
- Body position, blood oxygen level and limb movements are also monitored.
The entire night is recorded by video camera. A sleep technician is nearby the entire time you are studied. The technician is watching information recorded from all the monitors on your body.
A level 1 polysomnogram is useful for detecting almost all sleep disorders. This is the type of sleep test recommended for children.
