CPAP – What Is It?
CPAP or Constant Optimistic Airway Pressure is a mode of artificial ventilation of the lungs with the creation of constructive pressure in the airways after exhalation. At present, CPAP-remedy is used for the therapy of snoring, sleep apnea therapy, arterial hypertension, cardiovascular diseases, daytime sleepiness, obesity, impotence, insomnia, and depression. How can CPAP-remedy remedy so many ailments? It’s believed that every one of those illnesses are closely related to a disturbance of regular sleep.
Why is Sleep so Necessary?
Sleep helps the body to chill out from the stress with which a person is confronted each day. Throughout sleep, hormonal regulation happens in our body. Some hormones secrete solely throughout sleep, and some hormones secrete solely after sleep. Therefore, if Sleep apnea devices is impaired, it leads to a disturbance of the hormonal balance and nervous system transmitters, which ultimately causes the development of varied psychological and physical diseases. The principle cause of disturbance of regular sleep is sleep apnea.
Sleep apnea is an absence of pulmonary ventilation during sleep for more than 10 seconds, which is characterised by lowering of oxygen saturation in the blood (SaO2) by 4% or more. Usually, sleep apnea lasts for 20-30 seconds, nevertheless, in severe cases it will possibly final for two-3 minutes. The number of episodes of sleep apnea could sometimes be as much as 60% of the total nighttime sleep. Common sleep apnea (often not less than 10-15 occasions within an hour) is called obstructive sleep apnea syndrome. The main signs of the obstructive sleep apnea syndrome are daytime sleepiness, deterioration of memory and intelligence affecting means to work and a continuing sense of fatigue.
The main cause of obstructive sleep apnea syndrome is an obstruction of the higher airways. Obstruction of the higher airways means that air can’t get into the lungs and there is oxygen deprivation of the entire organism.
CPAP – Why is it Used?
Constant constructive airway pressure (CPAP) is an efficient methodology of treating obstructive sleep apnea syndrome. CPAP-remedy was introduced to clinical practice in 1981 by an Australian doctor and Professor. Colin Sullivan for the remedy of obstructive sleep apnea syndrome.
The mechanism of motion of the CPAP machine is quite simple. A small compressor is used for creating fixed air circulate beneath a sure pressure within the airways throughout exhalation via a flexible tube and a nose mask. Additionally it is used a humidifier that provides moisturizing and heats the air which enters the airways. This device does not permit the higher airways to be obstructed because of the fixed optimistic 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. Earlier than prescribing CPAP-remedy, a Polysomnography is required or in different words a Sleep Study. Polysomnography is a medical examination of a affected person’s sleep with the usage of specialized pc systems. Polysomnography permits calculating the apnea index and figuring out the severity of the disease.
The apnea index is the frequency of apnea episodes throughout 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 way, even more than 5 assaults of sleep apnea episodes are considered to be threatening for a person with a gradual development of daytime drowsiness, memory impairment, psycho-emotional problems, insomnia, development of cardiovascular illnesses (arterial hypertension, coronary coronary heart disease or stroke), and disturbance of cardiac rhythm.
CPAP – How is it Used?
The primary session of CPAP-remedy is carried out on the next night time after a diagnostic polysomnography. The purpose of the first CPAP session is to pick the minimum air pressure that eliminates obstructive apnea, loud night breathing and other respiratory disturbances in all positions of the body and in all phases of sleep. In the course of the first session of CPAP-remedy, the minimal set of parameters might be recorded: electroencephalography, electrooculography, electromyography, chest and abdominal movements, body position, loud night breathing, electrocardiography, blood saturation. These parameters help you decide the work of the mind and the stage of sleep, which excludes the possibility of insufficient air pressure via undiagnosed wakefulness episodes.
The “golden rule” is to use CPAP machine each evening throughout the whole time of sleep. Sufferers typically follow this advice in severe forms of obstructive sleep apnea. In this case, there may be an improvement within the high quality of sleep and daytime activity. Within the mild and moderate forms of the disease, the irritating impact of the mask and airflow might sometimes lower the standard of sleep, nevertheless, there’s a clear constructive impact on daytime exercise and on a number of different symptoms. One of the vital advantages of CPAP-remedy is the absence of side effects.
