CPAP or Constant Positive Airway Pressure is actually a mode of artificial ventilation of the respiratory system with the creation of positive pressure within 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, impote-nce, sleep problems, and depression. How can 睡眠呼吸機 cure so many diseases? It is believed that many of these diseases are closely associated with a disturbance of normal sleep.
The reason why Sleep essential?
Sleep helps your body to chill out from your stress that an individual is faced each day. While sleeping, hormonal regulation happens in your body. Some hormones secrete only during sleep, and a few hormones secrete only after sleep. Therefore, if sleep is impaired, it leads to a disturbance of the hormonal balance and central nervous system transmitters, which ultimately causes the growth of various psychological and physical diseases. The key reason behind disturbance of normal sleep is obstructive sleep apnea.
Obstructive sleep apnea is an absence of pulmonary ventilation while asleep for more than 10 seconds, that is seen as a decreasing of oxygen saturation within the blood (SaO2) by 4% or even more. Usually, sleep apnea can last for 20-30 seconds, nevertheless, in severe cases it will last for 2-3 minutes. The number of episodes of sleep apnea may often be as much as 60% in the total nighttime sleep. Regular sleep apnea (not often under 10-15 times inside an hour) is referred to as obstructive apnea syndrome. The key symptoms of the obstructive apnea syndrome are daytime sleepiness, deterioration of memory and intelligence affecting capability to work and a constant sense of fatigue.
The main cause of obstructive obstructive sleep apnea syndrome is surely an obstruction from the upper airways. Obstruction of the upper airways implies that air cannot go into the lungs and then there is oxygen deprivation in the whole organism.
CPAP – The reason why it Used?
Constant positive airway pressure (CPAP) is an efficient way of treating obstructive apnea syndrome. CPAP-therapy was exposed to clinical practice in 1981 by an Australian physician and Professor. Colin Sullivan for the treating of obstructive obstructive sleep apnea syndrome.
The mechanism of action of the CPAP device is quite easy. A tiny compressor can be used for creating constant air flow within a certain pressure inside the airways during exhalation via a flexible tube as well as a nose mask. It is additionally used a humidifier that gives moisturizing and heats air which enters the airways. This device will not permit the upper airways to become obstructed due to the constant positive air pressure and eliminates the primary reason behind the obstructive sleep apnea syndrome.
CPAP-therapy for patients with obstructive obstructive sleep apnea syndrome is currently universally accepted. Before prescribing CPAP-therapy, a Polysomnography is required or in other words a Sleep Study. Polysomnography is a medical study of a patient’s sleep with the aid of specialized computer systems. Polysomnography allows calculating the apnea index and determining the severity of the condition.
The apnea index is the frequency of apnea episodes during one hour of sleep. Apnea index determines the severity of the obstructive apnea syndrome. The apnea index is considered pathologically qtzdwy if there are more than 20 apnea episodes per hour, no matter the presence or deficiency of clinical symptoms. Anyway, much more than 5 attacks of apnea episodes are regarded as threatening for someone using a gradual 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 could it be Used?
The initial session of CPAP-therapy is performed on the next night after having a diagnostic polysomnography. The purpose of the initial CPAP session is to select the minimum air pressure that eliminates obstructive apnea, snoring and other respiratory disturbances in all positions in the body and in all stages of sleep. Through the first session of CPAP-therapy, the minimum list of parameters is going to be recorded: electroencephalography, electrooculography, electromyography, chest and abdominal movements, body position, snoring, electrocardiography, blood saturation. These parameters permit you to determine the task in the brain and also the stage of sleep, which excludes the chance of insufficient air pressure through undiagnosed wakefulness episodes.
The “golden rule” is by using CPAP machine every single night during the whole time of sleep. Patients often follow this recommendation in severe forms of obstructive obstructive sleep apnea. In this case, it comes with an improvement in the quality of sleep and daytime activity. Within the mild and moderate forms of the ailment, the irritating effect in the mask and airflow may sometimes decrease the standard of sleep, nevertheless, you will find a clear positive influence on daytime activity as well as on several other symptoms. One of the important advantages of CPAP-treatments are the absence of unwanted effects.
Needless to say, sometimes in the beginning, as with every method of treatment, there might be negative effects. Some of the most common complaints, this might be irritation of the skin underneath the mask (about 50%), dryness of the mucous membrane in 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 you should not interfere with the continuation of treatment. The usage of more comfortable masks and heating moisturizers effectively eliminates each one of these negative effects.
Also, there are a few recommendations how you can eliminate these unpleasant effects in the treatment:
1. To make use of CPAP-therapy each day during the first 4-5 hours of sleep. During this period of your time, there is the deepest dream and side effects from CPAP-therapy tend not to disturb the sufferer. Then within the other one half of sleep once the dream becomes superficial and also the mask or airflow actually starts to interfere, the mask can be removed and slept without this. It is important to admit the positive effect of treatment – decreasing the power of snoring and decreasing the number of apnea episodes continues during all of those other night.
2. To make use of CPAP-therapy with short breaks for 1-2 days. It is an intermittent use of CPAP-therapy. It is suggested to utilize CPAP-therapy a minimum of 70% of the nocturnal time. It really is strongly recommended when there is hypertension or some other cardiovascular diseases. Also, CPAP-therapy needs to be performed when a significant dose of alcohol or a sleeping pill was taken before sleep.
Despite the existence of such minor unwanted effects, 睡眠呼吸機 is regarded as the effective method of treating obstructive obstructive sleep apnea syndrome.
The usage of CPAP-therapy has made a huge contribution to solving the issue of therapy for cardiovascular disorders as well as other diseases and has led to a dramatic improvement in the quality and prognosis of the humans’ life.
