What is BiPAP Therapy?

Bilevel positive airway pressure (BiPAP) is a machine that helps people with complex respiratory conditions breathe more easily. BiPAP is used in hospitals, intensive care settings, and at home.  

It delivers air through a mask worn on the face. BiPAP is a noninvasive ventilation used when someone can breathe independently but has trouble getting enough oxygen or removing carbon dioxide. 

• “Bilevel” refers to the machine providing two air pressure levels: a higher pressure when you inhale (called inhalation positive airway pressure, or IPAP) and a lower pressure when you exhale (called exhalation positive airway pressure, or EPAP). 
• The term “positive airway pressure” means the machine pushes air at a higher pressure into the airway, which includes the nose, mouth, and windpipe. This helps keep the airway open and allows air to move more effectively into the lungs.

Definition and Overview

BiPAP involves using a machine that delivers air through a mask, providing two different pressure levels.  This bi-level feature of BiPAP can benefit users who find it challenging to exhale against CPAP’s continuous pressure.  

• Higher pressure when you inhale to keep your airways open.
• Lower pressure when you exhale to make breathing out easier.

The key parts of a BiPAP machine include: 

• Main Unit: Generates the airflow and adjusts the pressure settings.
• Mask: Fits over the nose, mouth, or both to deliver the air.
• Tubing: Connects the mask to the machine.
• Humidifier (optional): Adds moisture to prevent dryness and discomfort.

How Is BiPAP Different from CPAP?

Continuous positive airway pressure (CPAP) gives a steady, single level of pressure for both inhaling and exhaling, while BiPAP uses two pressure levels: higher for breathing in and lower for breathing out. This makes BiPAP more comfortable for people with trouble exhaling against constant pressure or needing extra breathing support.

• CPAP: Delivers a constant, single pressure level throughout both inhalation and exhalation.
• BiPAP: Offers two distinct pressure levels, making it more comfortable for some users, especially those with specific health conditions.

BiPAP is preferred over CPAP when a person has difficulty exhaling against the constant pressure of a CPAP machine. Your healthcare provider or a sleep specialist (somnologist) can determine if BiPAP or CPAP is best for you.

How BiPAP Works

BiPAP therapy utilizes two air pressure levels that help the lungs work more efficiently.

1. Inhalation Pressure (IPAP): BiPAP’s higher pressure during inhalation helps open the airways, ensuring enough air enters the lungs.
2. Exhalation Pressure (EPAP): BiPAP’s lower exhalation pressure makes breathing out feel natural and less restrictive.

What Conditions Is BiPAP Used For?

BiPAP helps people with complex or severe respiratory conditions breathe more easily, especially during sleep or when respiratory muscles are under strain. Conditions that BiPap is FDA-approved for include:   

• Sleep Apnea: Prevents airway collapse during sleep.
• COPD: Helps reduce the effort needed for breathing.
• Asthma: Eases breathing for those with limited lung function.
• Neuromuscular disorders that weaken the muscles involved in respiration: 
  • Amyotrophic Lateral Sclerosis (ALS) 
  • Muscular dystrophy
  • Multiple sclerosis
  • Spinal Muscular Atrophy 
  • Guillain-Barre Syndrome
• Obesity hypoventilation syndrome
• Congestive Heart Failure: BiPAP improves oxygenation and reduces breathing work.

It is important to note that the specific approval and use of BiPAP devices can vary based on the manufacturer, model, and the condition they are intended to treat. Always refer to the device labeling and consult a healthcare provider to confirm FDA-approved uses for a particular BiPAP machine.

Benefits and Applications of BiPAP

The benefits of BiPAP therapy include:  

• Improved Breathing and Reduced Work of Breathing - BiPAP machines provide two pressure levels: a higher pressure when inhaling and a lower pressure when exhaling. This dual-pressure system reduces the effort needed to breathe, especially for individuals with weakened respiratory muscles.
• Better Oxygenation and Quality of Sleep - BiPAP helps ensure better oxygen levels throughout the body by maintaining open airways and improving airflow. 
• Enhances sleep quality - Many users experience improved energy, reduced daytime sleepiness, and more restful sleep.  

Outcomes vary based on individual health needs and consistent use. Always consult a healthcare provider to determine if BiPAP therapy suits your needs.

Medical Applications

BiPAP therapy is versatile, addressing various chronic and acute conditions.

Chronic Respiratory Diseases

• COPD: BiPAP reduces the strain on the lungs, easing symptoms such as shortness of breath.
• Asthma: Helps during flare-ups by improving airflow and oxygen exchange.
• Neuromuscular Disorders: Supports breathing in conditions like ALS or muscular dystrophy, where respiratory muscles may weaken.

Acute Respiratory Conditions

• Respiratory Distress Syndrome (RDS): BiPAP is often used in hospitals for patients experiencing sudden breathing difficulties.
• Pneumonia: Assists with oxygen delivery when the lungs are inflamed or congested.
• Congestive heart failure: Helps improve oxygenation and reduce fluid buildup in the lungs, improving breathing efficiency.

Who Can Benefit from BiPAP Therapy?

BiPAP suitability is determined by specific medical needs and conditions a healthcare provider assesses.  

Patient Profiles

• Sleep Apnea Patients: Those who cannot tolerate CPAP therapy often find BiPAP more comfortable.
• People with Chronic Conditions: Individuals with COPD, asthma, or other chronic respiratory diseases may require BiPAP to manage symptoms effectively.
• Hospitalized Patients: Patients experiencing acute respiratory distress or who need support breathing after being extubated (removed) from mechanical (invasive) ventilation may be temporarily placed on BiPAP for breathing support.

Eligibility Criteria

• A prescription from a healthcare provider is required.
• Patients must have conditions that necessitate bi-level pressure support.
• BiPAP is often recommended for individuals who experience difficulty exhaling against CPAP’s constant pressure.

Using a BiPAP Machine

Using a BiPAP machine correctly is the first step toward effective therapy and comfortable use. With a few steps, you can ensure the device can provide the breathing support you need.

How to Set Up the Device

Setting up a BiPAP machine is straightforward and essential for effective therapy. Follow these steps:
