Polysomnography is a medical examination consisting in the recording, using multiple electrodes placed on the head, the face, the chest and the legs, during sleep of the patient, several respiratory physiological parameters (respiration rate, analysis tracheal, sound measurement of oro-nasal airflow and / or measurement of exhaled CO2), brain parameters, eye movements, muscle skeletal muscle activity, and the pace heart.

During polysomnography, the oximeter placed on a fingertip to determine changes in oxygen levels in the blood that occur because of sleep apnea and other respiratory problems. Polysomnography is used to study the different stages of sleep and the total duration of wakefulness and the number of arousals.

It helps to diagnose many types of sleep disorders, including obstructive sleep apnea, narcolepsy and restless legs. We can thus confirm a diagnosis, guide treatment and monitor or regression of an identified pathology.

Polysomnography can recognize the apneas and hypopneas, determine the type of apnea, obstructive or central, and appreciate the impact of sleep apnea on blood oxygenation and heart rate. This examination can be done in a hospital or outpatient.

Decreasing the amplitude and duration of the inspiratory depression, nasal dilator RespiFacile can be a stand-alone treatment of obstructive sleep apnea.
