CPAP or Constant Optimistic Airway Pressure is a mode of artificial ventilation of the lungs with the creation of optimistic pressure in the airways after exhalation. Currently, CPAP-therapy is used for the therapy of loud night breathing, sleep apnea treatment, arterial hypertension, cardiovascular ailments, daytime sleepiness, obesity, impotence, insomnia, and depression. How can CPAP-remedy remedy so many diseases? It is believed that all of those diseases are carefully related to a disturbance of normal sleep.
Why is Sleep so Important?
Sleep helps the body to calm down from the stress with which a person is confronted each day. During sleep, hormonal regulation happens in our body. Some hormones secrete solely throughout sleep, and a few hormones secrete only after sleep. Therefore, if sleep is impaired, it leads to a disturbance of the hormonal balance and nervous system transmitters, which finally causes the development of varied psychological and physical diseases. The primary cause of disturbance of normal sleep is sleep apnea.
Sleep apnea is an absence of pulmonary ventilation during sleep for more than resmed airsense 10 autoset seconds, which is characterized by lowering of oxygen saturation within the blood (SaO2) by 4% or more. Usually, sleep apnea lasts for 20-30 seconds, nevertheless, in severe cases it could possibly final for 2-3 minutes. The number of episodes of sleep apnea may typically be as much as 60% of the total nighttime sleep. Common sleep apnea (usually not less than 10-15 instances 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 skill to work and a continuing sense of fatigue.
The primary cause of obstructive sleep apnea syndrome is an obstruction of the upper airways. Obstruction of the higher airways means that air cannot get into the lungs and there may be oxygen deprivation of the entire organism.
CPAP – Why is it Used?
Constant optimistic airway pressure (CPAP) is an effective methodology of treating obstructive sleep apnea syndrome. CPAP-remedy was launched to medical observe in 1981 by an Australian physician and Professor. Colin Sullivan for the therapy of obstructive sleep apnea syndrome.
The mechanism of action of the CPAP device is quite simple. A small compressor is used for creating constant air circulate underneath a certain pressure in the airways throughout exhalation by 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 enable the higher airways to be obstructed because of the constant positive air pressure and eliminates the main cause of the obstructive sleep apnea syndrome.
CPAP-remedy for patients with obstructive sleep apnea syndrome is now universally accepted. Earlier than 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 using specialised computer systems. Polysomnography allows 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 scientific symptoms. By the 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 issues, insomnia, development of cardiovascular ailments (arterial hypertension, coronary 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 following night after a diagnostic polysomnography. The purpose of the primary CPAP session is to pick the minimal air pressure that eliminates obstructive apnea, snoring and different respiratory disturbances in all positions of the body and in all stages of sleep. Throughout the first session of CPAP-remedy, the minimal set of parameters can be recorded: electroencephalography, electrooculography, electromyography, chest and abdominal movements, body position, loud night breathing, electrocardiography, blood saturation. These parameters let you decide the work of the brain and the stage of sleep, which excludes the possibility of inadequate air pressure by means of undiagnosed wakefulness episodes.
The “golden rule” is to use CPAP machine each night during the entire time of sleep. Patients typically comply with this suggestion in extreme forms of obstructive sleep apnea. In this case, there is an improvement in the high quality of sleep and daytime activity. In the gentle and moderate types of the disease, the irritating effect of the mask and airflow might typically decrease the standard of sleep, nevertheless, there’s a clear optimistic impact on daytime activity and on a number of other symptoms. One of the necessary advantages of CPAP-therapy is the absence of side effects.
