Polysomnography is a comprehensive sleep study that is used to diagnose, or rule out, many types of breathing and sleep disorders. One of the major indications to conduct a polysomography is a suspicion of abnormal breathing patterns during sleep. Amongst the main symptoms are loud snoring, sleep apnea and tendency to fall asleep in various circumstances. Polysomnography is also conducted for patients suffering from insomnia, frequent awakeings and low quality of sleep. During the study various body functions are constantly monitored. Some of them include brain function, eye movement and muscle activity. Important part of the monitoring process is monitoring the breathing functions like airflow through the upper respiratory track, chest and stomach movements and blood oxygen saturation. In addition the PSG monitors the snoring and overall body sleep positions.
Preparation for PSG
We ask our patients to arrive for their test at 8:00 pm. There is a simple questionnaire that we ask to fill out prior to the PSG. We also need time to take patient`s measurements and place all of the necessary sensors. We provide a single room with a bathroom that is equipped with a shower. If patients wish to freshen up, we ask that they bring their own toiletries and a towel. For the purpose of the test we ask to wear a two piece button up pyjamas. We can provide an evening snack upon earlier request. As a reminder we ask to bring all of the usual medications tha patients are currently on. This is aspecially important if they are being taken for heart and blood pressure problems, diabetes and chronic respiratory disorders.
It is important to prevent troubles with falling asleep fot the test. For that reason we ask for the night before not to be too restful and to avoid drinking coffee, strong tea and other drinks containing caffeine, alcohol and other stimulating substances.
It is recommended that the PSG lasts at least 6 hours to ensure the most accurate results. The longer the test, the more information it gives. We try to follow the patient`a natural sleep cycle and have him fall asleepat the usual time. For the whoel duration of the test there is a nurse that monitors and supervises the patient. Nurse will adjust the sensors if needed and tend to patient`s needs during the PSG. If patient gets awaken, feel anxious, or needs to go to the bathroom we ask him to notify the monitoring nurse.
In the morning all of the sensors are detached and at about 7 am patients can leave our facility. Prior to leaving we ask patients to fill out one more questionnaire in relation to the PSG. After through all analysis our specialists will suggest proper treatment.
Otherwise, the method of assisted breathing. The patient sleeps in a mask through which the device through the night forces air into the airways. It seems unbearable, but patients who do not sleep well for years or wake up hundreds of times, after the first night with CPAP- do not want to give it up. The use of CPAP for sleep apnea syndrome gives an improvement in 95% of cases, resulting in normalization of sleep, improve oxygenation of the patient at night, relief of daytime sleepiness, improve overall well-being, and most importantly – significantly reduces the risk of complications such as heart attacks or strokes. KRAJMED offers patients a trial of CPAP treatment on loan-home for 1-2 nights. The patient convinced to this treatment may buy it for use in the home.
This is screening = basic, easy to make the study of sleep. It gives general information, if apnea occur and how they are dangerous. The test helps the physician identify appropriate recommendations.
