Diagnostics of respiratory disorders
Patients, who snore often struggle to breathe through nose at night, sleep inefficiently and are sleepy during the day, first require in-depth history of sleep disorder specialist (neurologist, pulmonologist, ORL specialist, diabetologist, cardiologist…)
Then a detailed clinical examination is made, both from internistic and neurological point of view. In structural disorders of the jaw, face or nose, it is also necessary to include ORL specialists and maxilofacial surgeons.
Further examinations include polysomnography and/or sleep polygraphy.
Polysomnography is a diagnostic procedure that overnight detects performance of various biological systems of patient. It usually takes place in a hospital in a specially adapted laboratory for sleep disorders. Sensors, which are attached to patient, monitor brain activity, movements of eyes, jaw muscles, legs, chest and abdomen, flow of air through the nose and body position during sleep. They also detect snoring, heart rate and saturation of blood with oxygen.
Sleep polygraphy is a diagnostic procedure similar to polysomnography, but is limited only to diagnostics of obstructive sleep apnea (OSA). It does not detect electric brain and muscle activity, the rest is the same as in polysomnography.
