Many companies of PAP machines are continuously developing different types of machines which will better provide patients with their needs. PAP machines are mostly used for the treatment of breathing disorders, especially sleep apnea. However, most PAP machines are specifically designed for obstructive sleep apnea, which does not really address the needs of other types of sleep apnea.
Sleep apnea is a common sleep disorder, but most people only have knowledge about obstructive sleep apnea, the most prevalent type of sleep apnea. This sleep apnea is caused by the enclosure of the airway, blocking the air passage and prevents the normal respiration of the affected individual. But there are other types of sleep apnea, and these are central and mixed sleep apneas.
Central sleep apnea is a neurological problem that also causes the cessation of breath during sleep. The brain fails to send proper signals to the respiratory system which causes the halt of respiratory cycles, making the breathing stop.
There are several causes of central sleep apnea, and most of them are very serious disorders and illnesses like bulbar poliomyelitis, encephalitis, neurodegenerative diseases, severe arthritis, severe obesity, stroke, primary hypoventilation system, and the use of narcotics. There is also idiopathic central sleep apnea which is not related to any other disease. For central sleep apnea, BiPAP and APAP machines are useful treatment equipment, but they do not provide maximum comfort that patients with central sleep apnea need.
There is a recent breakthrough from ResMed, a company that is dedicated to producing and developing treatment methods and equipment for sleep disordered breathing and other respiratory problems. The company has developed a new form of treatment specifically designed for central sleep apnea, as well as mixed sleep apnea, and all its forms. The company calls the new revolutionary method adaptive servo-ventilation.
The mechanism of adaptive servo-ventilation makes use of cutting-edge technology which enables the machine to provide the best respiratory support a sleep apnea patient needs, whether it is central, mixed, or even severe obstructive sleep apnea. It detects the breathing pattern of the patient on a breath-by-breath basis and assesses the average ventilation in order to adjust to a target ventilation best fitted to the breathing cycle of the patient. This makes sleep apnea almost or completely normalized to usual respiratory behavior.
Not only that, the pressure also adjusts according to the level of breathing that the patient exerts. The breathing rate and flow pattern of the patient is the basis with which the pressure of the air is synchronized. It also uses the Easy-Breathe technology of ResMed which makes use of a lower exhalation pressure, making exhalation more comfortable for a sleep apnea patient. The pressures of adaptive servo-ventilators also have a wider range as compared to ordinary PAP machines.
What’s good about these machines is that they are intelligent: adaptive servo-ventilators know when to adjust the ventilation system and how much to adjust it. When the apnea or breathing cessation occurs, the machine responds by providing the support that the respiration needs to normalize again. Once respiration is back to normal, the machine addresses it by gently minimizing the application of pressure to the airway. But it ensures that it provides adequate pressure to maintain the normal breathing pattern of the patient, keeping the respiration comfortable and reducing the work that the respiratory system needs to exert.
The excellent mechanism of adaptive servo-ventilators makes the machines very versatile to the needs of the patient, making it a perfect treatment method for central sleep apnea and other severe cases of the sleep disorder. This revolutionary technology that ResMed has introduced to the world is a real historical leap in the study and treatment of sleep apnea.
