What Are BiPAP Machines and How Do They Work?

Breathing problems can have a negative impact on your quality of life. Luckily, a variety of machines can assist you in breathing more easily. CPAP and APAP machines are well-known, but there are also BiPAP machines. The term “BiPAP” refers to a brand of device, whereas “BPAP” refers to the type of device.

BiPAP machines use pressure to force air into your lungs. This opens the lungs and increases the blood oxygen level based on the settings.

In this article, we’ll look at what BiPAP machines are, how they function, and what to anticipate if you use one.

What Exactly Is A BiPAP Machine and How Does It Function?

A BPAP is a type of non-invasive ventilation (NIV) therapy that is used to help people breathe. BPAP machines can be used in hospitals as well as at home for those who require them.

Home BPAP machines are small, roughly the size of a toaster. A tube connects the machine to a mask that is worn over your mouth and nose.

These machines are referred to as “bilevel” because they have two different air pressure settings:

  • When you breathe in, BiPAP machines increase the amount of air pressure in your lungs. This is also known as positive airway pressure.
  • When you exhale, the machine lowers the air pressure. This is referred to as expiratory positive airway pressure.

Some BPAP machines include a timer that can be set to maintain a certain number of breaths per minute.

What Is the Purpose of a BiPAP Machine?

At-home BPAP machines can be used to treat medical conditions that make breathing difficult. It may be beneficial for the following conditions:

  • Hypoventilation syndrome due to obesity.
  • COPD
  • Amyotrophic lateral sclerosis
  • Obstructive sleep apnea

In hospitals, BPAP machines could be used to treat breathing issues. Because they are non-invasive, they are frequently prefered over intubation.

Doctors typically use them in cases that do not necessitate intubation. A BPAP machine, for example, could be utilised to treat respiratory problems caused by pulmonary oedema or pneumonia. They are also used to ensure proper breathing after someone is removed from intubation.

What Can You Expect From a BiPAP Machine?

If you are prescribed a BiPAP machine, a respiratory specialist will usually set it up for you. The machine must be calibrated and the settings adjusted in accordance with your treatment plan. Your doctor will help you understand what to expect and how to use your BPAP machine correctly at home.

Depending on the condition, you may be asked to use it all of the time, some of the time, or only when you sleep. It is critical that you follow these instructions and use them as directed by your doctor or healthcare provider.

A BPAP machine consists of a tabletop unit with tubing, a motor, and a mask. You must be familiar with all of the components, as well as how they fit together and function. The machine will include detailed instructions on how to clean the mask and tubing.

A BPAP machine may be uncomfortable to use at first. You’ll likely grow accustomed to wearing the mask and the machine’s airflow over time. If you don’t, speak with your healthcare provider to see if the settings can be changed or if there is another option that might be better for you.

Side effects of BiPAP Machines

BiPAP machines are relatively safe, with a low risk of side effects. The majority of side effects are minor. They could include:

  • Mouth dryness
  • Bloating
  • Nasal dryness
  • Discomfort
  • Sinus pressure
  • Runny nose
  • Nasal dryness
  • Skin irritation

Discuss your symptoms with your healthcare provider. Adjustments are frequently possible to alleviate side effects, including mouth or nasal dryness and congestion.

Try loosening the mask if it’s too tight and causing redness or discomfort. If this doesn’t work, you can try mask liners, but the best choice is often to try a different size or style of mask.

It is critical that the mask not be too loose on your face, as this can reduce the pressure required for the BPAP to work properly. You can prevent this by checking the edges of the mask to guarantee that no air is escaping. Some devices even display a “mask leak” warning to let you understand if everything is in order.

Infections are uncommon, but they are possible. To reduce the risk of infection, clean the mask and tubing on a regular basis.


A BiPAP machine is a kind of ventilator used to treat chronic breathing conditions. It works similarly to a CPAP machine, but unlike a CPAP, which provides continuous air pressure, a BPAP provides two levels of air pressure. People with certain kinds of sleep apnea, as well as an obesity-hypoventilation syndrome, COPD, and neurological conditions that affect breathing, are usually advised to use a BPAP machine.
