Bilevel Positive Airway Pressure or BiPAP system has very comparable design and capabilities to a Continuous Positive Airway Pressure (CPAP) system. Unlike a CPAP system, a BiPAP system is a non-invasive therapy for individuals undergoing treatment for sleep apnoea. Both machines maintain throat muscular tissues from collapsing through the air pressure produced by way of the machines, performing as a splint to reduce obstructions. BiPAP and CPAP machines facilitate clean respiratory and uninterrupted sleep for people with obstructive sleep apnoea (OSA).
Unlike a CPAP system, a BiPAP gadget provides each adjustable inspiratory and decrease expiratory pressure. The inspiratory pressure helps easy respiration for the patient at the same time as the expiratory stress makes affected person exhalation less difficult. Generally, BiPAP machines have three operational modes and they may be:
1. Times–
in which the gadget switches among preprogrammed expiratory and inspiratory fee to make certain that the prescribed breaths per minute fee is sustained.
2. Spontaneous –
in which the machine switches among inspiratory and expiratory primarily based on what the BiPAP device senses at the switch on respiratory.
Three. Spontaneous/Timed-
wherein the device switches as it sense any exchange in respiratory. Overall, the quality is the time mode feature as it guarantees the system will supply the specified breathes consistent with minute rate.
A qualified doctor is required to determine which mode is satisfactory for the affected person.
Difference between a BiPAP and a CPAP
BiPAP and CPAP machines are both used for the remedy of sleep apnoea. However, there are differences of their features. A CPAP gadget provides continuous effective stress to assist manipulate sleep apnoea. This pressure is constant and is based on the consequences of the sleep have a look at of the patient. There are CPAP machines with car adjusting stress.

BiPAP device is considered more technologically advanced and is suggested for those who can not tolerate CPAP device remedy. The inhalation strain of a BiPAP is much like a CPAP however the exhalation pressure or EPAP is not. For a few, it’s miles hard to breathe towards consistent strain and this is in which BiPAP is beneficial as exhalation in this gadget has a decrease stress to permit affected person to breathe without difficulty. The drop in exhalation strain is maximum useful for CPAP patients prescribed with a 15 cm pressure or better. BiPAP exhalation strain can move down as little as 4cm, as a result stopping straining of the affected person and allow a more natural and secure enjoy.
Who Benefits from BiPAP Therapy?
BiPAP remedy is prescribed to treat sleep apnoea on human beings with low oxygen ranges or excessive stress settings. This sort of machine is most usually used on people whose sleep apnoea did now not get better on CPAP therapy. Patients with cardiopulmonary sickness consisting of congestive heart failure will benefit from BiPAP remedy. The same therapy is recommended for sufferers with neuromuscular disorders or lung disorders. Patients who suffer from ventilator impairment along with chronic obstructive pulmonary disorder (COPD), restrictive thoracic sickness, and weight problems-hypoventilation syndrome will advantage maximum from BiPAP therapy. Patients recognized with important sleep apnoea who are unresponsive to CPAP remedy are endorsed to switch to BiPAP therapy under a physician’s care. In most cases, patients who use BiPAP do no step down to the use of CPAP except there are amazing and vast modifications of their sleep apnoea diagnoses.
Benefits of BiPAP Therapy
BiPAP machines may also turn out to be the standard remedy for sleep apnoea due to correct compliance charges of sufferers using this machine, in comparison with CPAP. Based on blood gas degrees and clinical repute, this remedy appears to be more powerful. BiPAP system can supply Bi-Flex, and C-Flex that’s the emblem of expiratory strain relief of BiPAP generation, not best video display units the patient’s airflow at some point of exhalation but also reduces the pressure primarily based at the affected person’s desires. The stress is expanded on the stop of the expiration to save you the airway from collapsing.
