What is a Polysomnogram?

A Polysomnogram (PSG) or All Night Sleep Study (ANS) is a recording of various body functions including: brain waves (EEG), eye movements (EOG), heart rate (EKG), muscle tone (EMG), blood oxygen (SAO2), airflow and breathing effort (respiration).

How long does it last?

The study lasts approximately 7 hours, but may vary depending on your sleeping pattern.

How is the study performed?

A qualified PSG technologist will record the above mentioned functions after placing electrodes or monitors on your head, scalp, chest, legs, and abdomen, as well as a sensor placed near your nose and mouth.

Patients scheduled for CPAP/Bi-PAP:

Continuous positive air pressure (CPAP) or Bi-Level positive air pressure (Bi-PAP) will be administered through a nasal type mask to aid breathing during your sleep.

What is a Multiple Sleep Latency Test?

A Multiple Sleep Latency Test (MSLT) records the same body functions as listed above (EEG, EOG, EKG, EMG, SAO2, airflow and breathing effort).

How long does it last?

The study lasts approximately 10 hours, consisting of five naps every two hours. You will be required to stay awake in between naps so please bring things to occupy your time. A television and / or radio will be available in your room and breakfast and lunch will be provided.

How is the study performed?

A qualified MSLT technologist will record these functions after placing electrodes or monitors near the eyes, scalp, chin, and chest.
