Basal polysomnography

Patients spend the night in a comfortable room equipped to monitor physiological variables while sleeping, with audio and video recording when necessary.

The main variables simultaneously recorded during the night are brain and muscle electrical activity, eye movement, air flow through the nose and mouth, respiratory effort, and oxygen saturation, through sensors delicately placed on the skin with adhesive tape.

Since a technical team monitors the patient throughout the test, this is a type 1 polysomnography, which is the gold standard in sleep disorder diagnosis.

Basal polysomnography for infants up to 1 year old

Polysomnography for infants is similar to the procedure used for children and adults, with smaller sensors that are proportional to the infant’s size. The test can also be conducted during the day, for a period of at least 2 hours of sleep.

Polysomnography for PAP titration

Polysomnography for PAP titration is similar to basal polysomnography, but includes the use of a continued positive pressure device in the airways (CPAP, BPAP and Servo) through a face mask. The devices are used to treat obstructive apnea, hypo-ventilation, and central sleep apnea. The purpose of the test is to determine the best pressure at which to adjust the device.
