CPAP or Constant Positive Airway Pressure is actually a mode of artificial ventilation of the lungs with the development of positive pressure in the airways after exhalation. Currently, CPAP-treatment therapy is used for the management of snoring, apnea treatment, arterial hypertension, cardiovascular diseases, daytime sleepiness, obesity, erection problems, sleep problems, and depression. Just how can 睡眠窒息症 cure so many conditions? It is actually considered that most of these diseases are closely associated with a disturbance of normal sleep.
Exactly why is Sleep so Important?
Sleep helps our bodies to unwind through the stress with which one is faced each day. While asleep, hormonal regulation happens in your body. Some hormones secrete only while sleeping, and some hormones secrete only after sleep. Therefore, if sleep is impaired, it results in a disturbance from the hormonal balance and central nervous system transmitters, which ultimately causes the growth of various psychological and physical diseases. The primary cause of disturbance of normal sleep is obstructive sleep apnea.
Obstructive sleep apnea is an absence of pulmonary ventilation during sleep for more than 10 seconds, which is seen as a decreasing of oxygen saturation in the blood (SaO2) by 4% or even more. Usually, sleep apnea lasts for 20-thirty seconds, nevertheless, in severe cases it can last for 2-3 minutes. The number of episodes of apnea may sometimes be up to 60% from the total nighttime sleep. Regular sleep apnea (not often under 10-15 times in a hour) is referred to as obstructive obstructive sleep apnea syndrome. The main symptoms of the obstructive sleep apnea syndrome are daytime sleepiness, deterioration of memory and intelligence affecting capability to work along with a constant feeling of fatigue.
The main reason for obstructive apnea syndrome is definitely an obstruction from the upper airways. Obstruction in the upper airways means that air cannot go into the lungs and there is oxygen deprivation of the whole organism.
CPAP – Exactly why is it Used?
Constant positive airway pressure (CPAP) is an efficient way of treating obstructive sleep apnea syndrome. CPAP-therapy was introduced to clinical practice in 1981 by an Australian physician and Professor. Colin Sullivan for the management of obstructive obstructive sleep apnea syndrome.
The mechanism of action of the CPAP device is fairly simple. A small compressor is utilized for creating constant ventilation within certain pressure inside the airways during exhalation by way of a flexible tube and a nose mask. It is also used a humidifier that provides moisturizing and heats the environment which enters the airways. This product will not permit the upper airways to be obstructed as a result of constant positive air pressure and eliminates the primary reason behind the obstructive sleep apnea syndrome.
CPAP-therapy for patients with obstructive sleep apnea syndrome is now universally accepted. Before prescribing CPAP-therapy, a Polysomnography is necessary or in other words a Sleep Study. Polysomnography is a medical study of a patient’s sleep by using specialized computer systems. Polysomnography allows calculating the apnea index and determining the severity of the condition.
The apnea index will be the frequency of apnea episodes during 1 hour of sleep. Apnea index determines the degree of the obstructive obstructive sleep apnea syndrome. The apnea index is regarded as pathologically qtzdwy if there are more than 20 apnea episodes each hour, whatever the presence or absence of clinical symptoms. Incidentally, much more than 5 attacks of sleep apnea episodes are regarded as threatening for an individual having a gradual progression of daytime drowsiness, memory impairment, psycho-emotional disorders, insomnia, progression of cardiovascular diseases (arterial hypertension, coronary heart problems or stroke), and disturbance of cardiac rhythm.
CPAP – How could it be Used?
The first session of CPAP-treatments are performed on the next night after having a diagnostic polysomnography. The objective of the initial CPAP session is to pick the minimum air pressure that eliminates obstructive apnea, snoring along with other respiratory disturbances in all positions of the body and in all stages of sleep. Through the first session of CPAP-therapy, the minimum set of parameters is going to be recorded: electroencephalography, electrooculography, electromyography, chest and abdominal movements, body position, snoring, electrocardiography, blood saturation. These parameters allow you to determine the task of the brain as well as the stage of sleep, which excludes the chance of insufficient air pressure through undiagnosed wakefulness episodes.
The “golden rule” is by using CPAP machine each night during the entire time of sleep. Patients often follow this recommendation in severe kinds of obstructive obstructive sleep apnea. In this instance, it comes with an improvement in the standard of sleep and daytime activity. In the mild and moderate types of the condition, the irritating effect in the mask and airflow may sometimes decrease the standard of sleep, nevertheless, there is a clear positive impact on daytime activity and also on a number of other symptoms. One of many important advantages of CPAP-treatment therapy is the absence of negative effects.
Needless to say, sometimes at first, as with every way of treatment, there may be negative effects. One of the most common complaints, this might be irritation of the skin beneath the mask (about 50%), dryness in the mucous membrane of the nose and pharynx (about 30%), nasal congestion or rhinorrhea (about 25%), eye irritation (about 25%). However, these symptoms are certainly not serious, they eventually disappear and do not hinder the continuation of treatment. The usage of more comfortable masks and heating moisturizers effectively eliminates all of these side effects.
Also, there are a few recommendations how you can eliminate these unpleasant effects inside the treatment:
1. To utilize CPAP-therapy every day throughout the first 4-5 hours of sleep. During this time of energy, there is a deepest dream and side effects from CPAP-therapy do not disturb the patient. Then inside the other one half of sleep if the dream becomes superficial as well as the mask or airflow actually starts to interfere, the mask can be taken off and slept without this. It is important to admit the positive effect of treatment – reducing the intensity of snoring and decreasing the quantity of apnea episodes continues during the remainder of the night.
2. To use CPAP-therapy with short breaks for 1-2 days. It is an intermittent utilization of CPAP-therapy. It is recommended to use CPAP-therapy at the very least 70% in the nocturnal time. It is actually strongly recommended when there is hypertension or some other cardiovascular diseases. Also, CPAP-therapy needs to be performed if a significant dose of alcohol or even a sleeping pill was taken before sleep.
Despite the actual existence of such minor unwanted effects, 睡眠呼吸機 is easily the most effective approach to treating obstructive sleep apnea syndrome.
The usage of CPAP-therapy has created a huge contribution to solving the situation of management of cardiovascular disorders as well as other diseases and contains triggered a dramatic improvement in the quality and prognosis from the humans’ life.
