Our center performs spirometry, DLCO-diffusing capacity of the lungs for carbon monoxide, and PEF measurement to measure pulmonary functions using standard devices as well as highly specific cardiorespiratuar exercise testing to get an answer to many questions. These tests help understand the cause of shortness of breath, evaluate preoperative capacity of the lungs, and measure exercising performance, and calculate use of oxygen, production of carbon dioxide and many respiratory parameters, and monitor the blood pressure.
Polysomnography is used to diagnose several sleep disorders such as snoring, sleep apnea, and periodic leg movements during sleep. In polysomnography, brain waves, eye movements and respiratory functions of a patient and oxygen percentage in the blood and muscular activity can be monitored during sleep. The patients that will undergo polysomnographic examination should have no sleep during the day, take no alcohol, not drink too much coffee or tea that may impair regular sleep routine, and take no sleeping aids.
Sleep technician first describes the procedures then attaches the electrodes for recording. After attaching the electrodes, another technician who will monitor the process gets in the monitoring room to monitor and record all signals from the electrodes via a computer. A camera installed in the bedroom will also record the patient all night long. The records of the night are analyzed by the physician to diagnose and plan the treatment
