CPAP or Constant Positive Airway Pressure is a mode of artificial ventilation of the lungs with the creation of positive pressure in the airways after exhalation. Currently, CPAP-treatments are utilized for the management of snoring, obstructive sleep apnea treatment, arterial hypertension, heart diseases, daytime sleepiness, obesity, erection problems, sleeplessness, and depression. Just how can 睡眠呼吸機 cure numerous disorders? It is thought that all of these diseases are closely associated with disturbance of normal sleep.
The reason why Sleep so Important?
Sleep helps your body to chill out from your stress in which a person is faced every day. While asleep, hormonal regulation happens in the body. Some hormones secrete only during sleep, and a few hormones secrete only after sleep. Therefore, if sleep is impaired, it results in a disturbance from the hormonal balance and nervous system transmitters, which ultimately causes the growth of various psychological and physical diseases. The key reason behind disturbance of normal sleep is sleep apnea.
Apnea is definitely an deficiency of pulmonary ventilation while sleeping for more than 10 seconds, that is seen as a decreasing of oxygen saturation inside the blood (SaO2) by 4% or even more. Usually, apnea will last for 20-half a minute, nevertheless, in severe cases it can last for 2-3 minutes. The number of instances of obstructive sleep apnea may often be up to 60% from the total nighttime sleep. Regular apnea (not often lower than 10-15 times in a hour) is known as obstructive obstructive sleep apnea syndrome. The primary signs and symptoms of the obstructive obstructive sleep apnea syndrome are daytime sleepiness, deterioration of memory and intelligence affecting capability to work and a constant sensation of fatigue.
The main reason behind obstructive obstructive sleep apnea syndrome is definitely an obstruction in the upper airways. Obstruction of the upper airways signifies that air cannot go into the lungs and then there is oxygen deprivation of the whole organism.
CPAP – Why is it Used?
Constant positive airway pressure (CPAP) is an efficient method of treating obstructive obstructive sleep apnea syndrome. CPAP-therapy was brought to clinical practice in 1981 by an Australian physician and Professor. Colin Sullivan for the treating of obstructive sleep apnea syndrome.
The mechanism of action from the CPAP device is quite simple. A small compressor is used for creating constant air-flow within a certain pressure within the airways during exhalation through a flexible tube and a nose mask. It is additionally used a humidifier which offers moisturizing and heats the environment which enters the airways. This product fails to allow the upper airways to be obstructed due to the constant positive air pressure and eliminates the main reason for the obstructive apnea syndrome.
CPAP-therapy for patients with obstructive apnea syndrome is now universally accepted. Before prescribing CPAP-therapy, a Polysomnography is required or in other words a Sleep Study. Polysomnography is actually a medical examination of a patient’s sleep by using specialized computer systems. Polysomnography allows calculating the apnea index and determining the degree of the ailment.
The apnea index is definitely the frequency of apnea episodes during 60 minutes of sleep. Apnea index determines the severity of the obstructive obstructive sleep apnea syndrome. The apnea index is considered pathologically qtzdwy if there are more than 20 apnea episodes hourly, no matter the presence or deficiency of clinical symptoms. Anyway, a lot more than 5 attacks of apnea episodes are regarded as threatening for a person having a gradual growth and development of daytime drowsiness, memory impairment, psycho-emotional disorders, insomnia, growth and development of cardiovascular diseases (arterial hypertension, coronary cardiovascular disease or stroke), and disturbance of cardiac rhythm.
CPAP – How will it be Used?
The very first session of CPAP-treatment therapy is performed on the next night after having a diagnostic polysomnography. The purpose of the first CPAP session is always to select the minimum air pressure that eliminates obstructive apnea, snoring and other respiratory disturbances in all positions from the body as well as in all stages of sleep. During 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 from the brain as well as the stage of sleep, which excludes the potential of insufficient air pressure through undiagnosed wakefulness episodes.
The “golden rule” is by using CPAP machine every night during the entire time of sleep. Patients often follow this recommendation in severe types of obstructive sleep apnea. In cases like this, it comes with an improvement in the caliber of sleep and daytime activity. In the mild and moderate forms of the ailment, the irritating effect of the mask and airflow may sometimes decrease the caliber of sleep, nevertheless, you will find a clear positive influence on daytime activity as well as on a number of other symptoms. Among the important features of CPAP-therapy is the lack of negative effects.
Obviously, sometimes at first, as with every method of treatment, there might be unwanted effects. Some of the most common complaints, this may be irritation of the skin under the mask (about 50%), dryness from the mucous membrane from the nose and pharynx (about 30%), nasal congestion or rhinorrhea (about 25%), eye irritation (about 25%). However, these symptoms usually are not serious, they eventually disappear and never interfere with the continuation of treatment. The use of more at ease masks and heating moisturizers effectively eliminates each one of these side effects.
Also, there are a few recommendations how you can eliminate these unpleasant effects within the treatment:
1. To utilize CPAP-therapy each day throughout the first 4-5 hours of sleep. During this period of time, you have the deepest dream and adverse effects from CPAP-therapy tend not to disturb the patient. Then inside the other 50 % of sleep if the dream becomes superficial and the mask or airflow begins to interfere, the mask can be taken off and slept without this. It is essential to admit that this positive effect of treatment – reducing the intensity of snoring and decreasing the number of apnea episodes continues during the remainder of the night.
2. To make use of CPAP-therapy with short breaks for 1-2 days. It is really an intermittent usage of CPAP-therapy. It is suggested to use CPAP-therapy at the very least 70% from the nocturnal time. It is actually strongly recommended if you have hypertension or any other cardiovascular diseases. Also, CPAP-therapy should be performed when a significant dose of alcohol or even a sleeping pill was taken before sleep.
Despite the existence of such minor side effects, 睡眠窒息症 is regarded as the effective method of treating obstructive sleep apnea syndrome.
Using CPAP-therapy makes a huge contribution to solving the situation of therapy for cardiovascular disorders along with other diseases and it has led to a dramatic improvement in the quality and prognosis from the humans’ life.
