CPAP or Fixed Optimistic Airway Pressure is a mode of synthetic ventilation of the lungs with the creation of constructive pressure in the airways after exhalation. At the moment, CPAP-therapy is used for the treatment of snoring, sleep apnea remedy, arterial hypertension, cardiovascular ailments, daytime sleepiness, weight problems, impotence, insomnia, and depression. How can CPAP-therapy cure so many illnesses? It’s believed that each one of these ailments are carefully associated with a disturbance of normal sleep.
Why is Sleep so Necessary?
Sleep helps the body to loosen up from the stress with which a person is faced each day. During sleep, hormonal regulation occurs in our body. Some hormones secrete solely during sleep, and a few hormones secrete solely after sleep. Due to this fact, if sleep is impaired, it leads to a disturbance of the hormonal balance and nervous system transmitters, which finally causes the development of assorted psychological and physical diseases. The main cause of disturbance of normal sleep is sleep apnea.
Sleep apnea is an absence of pulmonary air flow throughout sleep for more than 10 seconds, which is characterized by decreasing of oxygen saturation within the blood (SaO2) by four% or more. Normally, sleep apnea lasts for 20-30 seconds, nevertheless, in severe cases it will probably last for 2-three minutes. The number of episodes of sleep apnea might typically be up to 60% of the total nighttime sleep. Regular sleep apnea (normally not less than resmed airsense 10 autoset-15 occasions within an hour) is called obstructive sleep apnea syndrome. The principle symptoms of the obstructive sleep apnea syndrome are daytime sleepiness, deterioration of memory and intelligence affecting skill to work and a continuing sense of fatigue.
The principle cause of obstructive sleep apnea syndrome is an obstruction of the upper airways. Obstruction of the upper airways signifies that air can’t get into the lungs and there may be oxygen deprivation of the whole organism.
CPAP – Why is it Used?
Constant positive airway pressure (CPAP) is an efficient methodology of treating obstructive sleep apnea syndrome. CPAP-remedy was launched to scientific observe in 1981 by an Australian physician and Professor. Colin Sullivan for the treatment of obstructive sleep apnea syndrome.
The mechanism of action of the CPAP device is sort of simple. A small compressor is used for creating constant air move beneath a sure pressure in the airways during exhalation by way of a flexible tube and a nostril mask. It is also used a humidifier that gives moisturizing and heats the air which enters the airways. This gadget does not enable the upper airways to be obstructed because of the fixed constructive air pressure and eliminates the primary cause of the obstructive sleep apnea syndrome.
CPAP-remedy for sufferers with obstructive sleep apnea syndrome is now universally accepted. Before prescribing CPAP-therapy, a Polysomnography is required or in different words a Sleep Study. Polysomnography is a medical examination of a patient’s sleep with the usage of specialised laptop systems. Polysomnography permits calculating the apnea index and figuring out the severity of the disease.
The apnea index is the frequency of apnea episodes during one hour of sleep. Apnea index determines the severity of the obstructive sleep apnea syndrome. The apnea index is considered pathologically significant if there are more than 20 apnea episodes per hour, regardless of the presence or absence of medical symptoms. By the best way, even more than 5 assaults of sleep apnea episodes are considered to be threatening for an individual with a gradual development of daytime drowsiness, memory impairment, psycho-emotional problems, insomnia, development of cardiovascular ailments (arterial hypertension, coronary heart disease or stroke), and disturbance of cardiac rhythm.
CPAP – How is it Used?
The first session of CPAP-therapy is carried out on the subsequent evening after a diagnostic polysomnography. The purpose of the first CPAP session is to pick the minimum air pressure that eliminates obstructive apnea, snoring and different respiratory disturbances in all positions of the body and in all phases of sleep. Through the first session of CPAP-remedy, the minimum set of parameters shall be recorded: electroencephalography, electrooculography, electromyography, chest and stomach movements, body place, snoring, electrocardiography, blood saturation. These parameters help you determine the work of the mind and the stage of sleep, which excludes the opportunity of inadequate air pressure by undiagnosed wakefulness episodes.
The “golden rule” is to use CPAP machine every evening throughout your complete time of sleep. Patients usually observe this suggestion in severe forms of obstructive sleep apnea. In this case, there is an enchancment within the high quality of sleep and daytime activity. Within the mild and moderate forms of the illness, the irritating impact of the mask and airflow might generally decrease the quality of sleep, nevertheless, there is a clear positive impact on daytime exercise and on a number of other symptoms. One of many essential advantages of CPAP-therapy is the absence of side effects.
