Bi-level PAPs are breathing Devices – Advantages and Disadvantages of BiPAP machines

Bi-level PAP (Bi-level positive airway pressure) or BiPAP machines are devices used for breathing purposes. They are alike CPAP devices used to treat patients having obstructive or central sleep apnea.
Bi-level means that the air is delivered during inhalation of the patient under high pressure and change to a low pressure while breathing out of a patient, thus making it simpler for the patient to respire.
Bi-level PAP device is normally suggested by therapist for patients who are having difficulty in their CPAP treatment or have severe or central sleep apnea.




Why Bi PAP is recommended against CPAP?

The Bi PAP machine was invented for people who have difficulty exhaling against the pressure of CPAP, or having respiratory failure, and make the treatment more tolerable.
The Bi-level positive airway pressure machine was made for patients having trouble breathing out with CPAP or for people having respiratory breakdown to make the respiratory process more bearable.
The BPAP machine can be used in place or CPAP in case a patient is unable to bear the high pressure of CPAP. In case of BIPAP the pressure will be lower while breathing out and the respiratory process will be extra effective and comfortable.




What Type of Patients need Bi-PAP?

BiPAP machine can be used in the below mentioned conditions:
Patients who feel extraordinary pressure or uneasiness while breathing out may need BiPAP device.

Inadequately treated CPAP patients may require Bi-Level therapy or they may need APAP therapy.

Patients, basically suffering from ventilator impairment for e.g. chronic obstructive pulmonary disease (COPD), restrictive thoracic disorder, or obesity hypoventilation syndrome may need Bi-Level treatment.

Central Sleep Apnea sufferers may also be given BiPAP therapy.

Bi-PAP therapy can be utilized in cases of different neuromuscular illnesses or treating adult respiratory distress syndrome (ARDS).

The Advantages of Bi-Level Treatment
In the near future, Bi-pap machines will be considered the standard treatment for sleep apnea, considering all the superior benefits compared with CPAP:
Bi-Level treatment is likely to be measured as the normal therapy for curing sleep apnea due to its higher advantages over CPAP:
  • BiPAP machines have shown much compliance with the majority of patients. 
  • It has shown perfection in maintaining oxygen levels in the blood.
  • The new C-Flex technology in Bi-PAP checks the airflow of the patient and adjusts the pressure as per his response and needs. C-Flex has demonstrated great levels of comfort and adherence to the patients.
  • Bi-Level therapy can treat central sleep apnea associated with cerebrovascular mishap or cardiac breakdown.
  • COPD patients can get relief from Bi-Level treatment as opposed to CPAP therapy, where it is difficult for patients to breathe out against the CPAP pressure.

Drawbacks of Bi-Level Treatment
In few instances, the Bi-Level titration may cause central sleep apnea to occur. The actual reason is not sure, however, is perhaps because of improved volume of lung at times the inhalation air (IPAP) is considerably higher as compared to the exhalation air (EPAP).
One more drawback is the high price of BiPAP devices that is considerably on the higher side as compared to CPAP device. If you wish to rent a Bi-PAP machine the cost is US$350 monthly, whereas, the total cost for buying the Bi-PAP machine is approximately US$3000.
Several other drawbacks are alike CPAP such as:
Rhinitis
Nasal congestion
Dry nose
Common uneasiness
Mask air leaks
