The patient calls and wakes an appointment for the exam of polysomnography. At the moment of the consultation, the physician requirement will be checked as well as the kind of polysomnography is being asked, the requirement date, and the patients medical insurance.
The patients that presents clinical symptoms of the disease (snoring, sleepiness symptom during the day, etc) should have a study of the sleepiness be a polysomnography.
The polysomnography is the chosen exam in the diagnosis of the obstructive sleeping apnea and consists in registering the physiological variables during the sleep as the brain electrical activity, eye movement, muscle tonus oral and nasal air flow, breathing effort, legs movement, blood oxygenation (oxygenmetry). This exam besides diagnosing will determine how severe the pathology is.
The polysomnography will determine if your sleep is regular and presents enough deep sleep, if it presents little awakens, fragmenting the sleep breathing control, measuring the intensity of nasal and mouth air flow, and also registering if there is flow interruption (breathing stops), registering chest and belly movements.
Snoring records and determining if it is of strong intensity and intermittent, amount of oxygen in the blood using non-invasive digital sensors, body movement control during the exam with monitoring of the chest and restless legs.
The CPAP (Continuous Positive Airway Pressure) is one of the alternatives your physician may choose form as a treatment. This way you may have another exam of polysomnography using this equipment to identify the CPAP pressure to be used by the patient at home.
Bi-level Positive Airway Pressure (positive pressure in airways at two levels) is a pressurizer that inflates the superior airways so that hypo-apnea and sleep apnea can be minimized.
There are two different pressure levels, one for inspiration and one for expiration.
