Bipap stands for Bilevel positive airway pressure and is quite similar in function and structure to a CPAP machine (continuous positive airway pressure). Bipap and Cpap, they both are a non-invasive therapy for patients experiencing sleep apnea. The device gives pressurized air through a mask to the patient’s airways. Both CPAP and BiPAP machines enable patients to breathe easily and regularly throughout the night.
CPAP and BiPAP machines look alike, both have the same attachments, and both use the same CPAP mask and supplies. Though, each sleep apnea treatment is used for a specific purpose and has its own benefits. CPAP devices are basically used to treat hampering sleep apnea, while BiPAP devices are used to treat central sleep apnea, complex sleep apnea or COPD.
The key difference between BiPAP and CPAP devices is that BiPAP machines can be set in two pressure settings. The dual settings enable the patient to acquire more air in and out of their lungs.
If talking about the pricing, historically BiPAP is considered to be more expensive than CPAP. Its upto the preference of an individual, but usually BiPAP is mostly used when CPAP cannot be endured by the user. The main benefit of a BiPAP machine is that the strain is less during expiration. It limits the amount of energy expended while exhalation. Otherwise, it can be said that it is simpler to breath out with Bipap than with CPAP.
The therapy mainly depends on your needs. CPAP would be the right choice, if your pressure hasn’t altered much from a long period. BiPAP certainly is best, if you require a higher pressure or other conditions.
Still, you will need to have a doctor's prescription to purchase a CPAP or BiPAP device. The effective devices can easily be purchased online.
