BiPAP (bilevel positive airway pressure) is a non-invasive ventilation therapy used to treat sleep apnea and other respiratory conditions. It delivers pressurized air through a mask at two alternating pressure levels - a higher inspiratory positive airway pressure (IPAP) and a lower expiratory positive airway pressure (EPAP) that mimic the patient's natural breathing pattern. BiPAP is prescribed for patients with obstructive sleep apnea who have not responded well to CPAP or who have other cardiopulmonary disorders. It provides an alternative to mechanical ventilation for respiratory support in hospitalized patients.

2. What Is BiPAP or Bilevel Therapy?
• BiPAP (also referred to as BPAP) stands for Bilevel Positive Airway Pressure.
• It is very similar in function and design to a CPAP machine (continuous
positive airway pressure).
• A BiPAP machine is a non-invasive form of therapy for patients suffering
from sleep apnea.
• Sleep apnea, also spelled sleep apnoea, is a sleep disorder where a person
has pauses in breathing or periods of shallow breathing during sleep
• Central sleep apnea occurs because your brain doesn't send proper signals
to the muscles that control your breathing
• Both machine types deliver pressurized air through a mask to the patient's
airways.
• The air pressure keeps the throat muscles from collapsing and reducing
obstructions by acting as a splint.
• Both CPAP and BiPAP machines allow patients to breathe easily and
regularly throughout the night

3. Bilevel Pressure
• The key distinguishing feature of BiPAP is that the pressurized air is delivered at
two alternating levels.
• The inspiratory positive airway pressure (IPAP) is higher and supports a breath as
it is taken in. Conversely,
• The expiratory positive airway pressure (EPAP) is a lower pressure that allows
you to comfortably breathe out.
• These pressures are preset based on a prescription provided by your sleep doctor
and alternate just like your breathing pattern.
• Beyond these standard settings, there are a few other variations that are
available. Bilevel ST includes the timed delivery of a breath if breathing pauses
occur. These pauses are often present in central sleep apnea.
• In addition, auto or adaptive servo-ventilation (ASV) includes more sophisticated
settings that vary the timing, length, and volume of the breaths that are delivered

9. Where can use BiPAP Therapy?
• BiPAP machines are often prescribed to obstructive sleep apnea, sleep
apnea patients with high pressure settings or low oxygen levels.
• BiPAPs are often used after CPAP has failed to adequately treat certain
patients.
• BiPAPs can be helpful for patients with cardiopulmonary disorders such as
congestive heart failure.
• Often prescribed to people with lung disorders or certain neuromuscular
disorders. amyotrophic lateral sclerosis
• BiPAP is a method of breathing support that is often used to treat central
sleep apnea, a condition that occurs in the setting of opioid use, congestive
heart failure, and prior stroke
• it is a non-invasive means of support that can be used in hospitalized
people who are in respiratory distress but who do not wish to be placed on
a ventilator
