Not everytime does CPAP comes to rescue and there are times and certain conditions when physicians turn to an alternate non-invasive ventilator therapy known as BiPAP or bi-level positive airway pressure. The two most common clinical indications for BiPAP include both obstructive and central sleep apnea.
What is Bilevel Therapy
A BiPAP machine greatly resembles CPAP machine as they consist of a face mask and a tubing that is attached to the equipment. However, BiPAP functions a bit differently as it provides pressurized air at two levels as indicated by the name; bi-level. These two levels are alternating (similar to the normal breathing physiology) as the inhaled air or the inspiratory positive airway pressure (IPAP) is of higher pressure than the exhaled positive airway pressure (EPAP) that makes it easier for a person to breath and takes off load from the respiratory muscles and the heart.
There are few customized settings that a BiPAP machine and varies from device to device which can be thoroughly understood by a buying guide. Apart from bi-level pressure, a BiPAP machine also features the bilevel ST which provides precise delivery of breath in case of a breath pause which is very common in central sleep apnea. Additionally, adaptive servo-ventilation which renders a more advanced customization of time, duration and volume of breath to facilitate breathing.
Using BiPAP to Treat Sleep Apnea
Sleep apnea is generally described as sleep disorder in which the regular breathing pattern is greatly impaired and can result in periodic stop of breath followed by the commencement of respiration. One of the most common indications of sleep apnea include snoring and tiredness despite a good night’s sleep. BiPAP is beneficial in such conditions when the alternative CPAP makes it difficult for patients to exhale against a continuous greater pressure, thereby increasing compliance amongst such patients.
