BiPAP Settings-Why You Should Know About It


BiPAP Settings

A BiPAP machine works two ways unlike a CPAP machine it has a variable inspiratory pressure and a lower expiratory pressure. During the sleep the inspiratory pressure makes it easier to breathe while the expiratory pressure makes it easier to exhale. As based upon the prescription from the doctor the BiPAP machine levels are already set.

The machine runs on three modes of operation.

  • (S) Spontaneous – switching between inspiratory and expiratory as the BiPAP machine senses the switch in breathing.
  • (T)Timed – switching between inspiratory and expiratory at a programmed rate to ensure the prescribed breaths per minute rate is maintained.
  • (S/T)Spontaneous/Timed – switches as it senses the change in breathing. Timed mode functions as a failsafe to ensure breathing at the required breathes per minute rate is maintained.

BiPAP Settings 

With BiPAP, the IPAP setting may range from 4-24 cmH2O, while the EPAP setting may vary from 2-20 cmH2O. Typical initial settings for BiPAP are levels of 8-10 cmH2O IPAP and 2-4 cmH2O EPAP. These settings presume that the lower pressures will allow patient tolerance and training. When using BiPAP, remember that the inspiratory pressure must be maintained higher than the expiratory pressure at all times to ensure bi-level flow. Flow must be synchronized with patient respiratory efforts.

Pressure Support Ventilation Settings

typical initial pressure support ventilation would be 8-10 cmH2O combined with PEEP of 2-4 cmH2O. (This is equivalent to BiPAP with IPAP at 8-10 cmH2O and EPAP at 2-4 cmH2O.)

The Real Difference between CPAP and BIPAP Therapy


Positive airway pressure therapy is a respiratory treatment that’s used to treat different types of sleep apnea and other types of respiratory failure. Apnea is a type of respiratory condition that is characterized by the interruption of breathing that will periodically disrupt the sleep of the individual. This is due to the air passages that carry air to the lungs becoming too narrow. This prevents the air from passing through them and can lead to a dip of oxygen levels in the body. Commonly, your sleep specialist will recommend either CPAP or BIPAP therapy. There is a significant difference between CPAP and BIPAP therapy that we will discuss here.

Difference between CPAP and BIPAP Therapy: Which one is right for you?

sleep-apnoea-devicePeople with sleep apnea are familiar with Continuous Positive Air Pressure therapy and Bi Level Positive Air Pressure Therapy. These machines will allow the user to breathe easily during sleep. Both types of these devices make use of the PAP technique in order to help clear the airways and allow for easier breathing.

The main difference between CPAP and BIPAP machines is the levels of air pressure. The CPAP machine will provide a specific level of air pressure and release gusts of air through a hose that is connected to a face mask. This air pressure will keep the upper airways open, preventing episodes of obstructive sleep apnea from occurring. CPAP can also be used to treat respiratory conditions.

BIPAP machines deliver two different levels of air, one level for inhaling and another lower setting for exhaling. BIPAP therapy can be used to treat obstructive sleep apnea, heart disease and different types of respiratory conditions.

CPAP machines were originally designed to solely treat apnea and they’re also used to treat patients with respiratory problems and neuromuscular diseases. BIPAP machines are also used to treat heart disease.

CPAP machines work by delivering a single level of air pressure, which can’t be altered. BIPAP machines feature two different levels of air pressure- low when the user exhales and high when they inhale. The BIPAP machine also allows you to alter the level of air pressure.

CPAP vs. BIPAP: The Bottom Line

Individuals who use CPAP therapy need to exert additional force against the air pressure when they exhale, because the air pressure remains constant. This can disrupt the user’s sleep at times and cause discomfort or false feelings of suffocation. With BIPAP machines, the air pressure is set at high and low, making it more user friendly.

CPAP machines cost less when compared to BIPAP devices. People who have used both types of apnea therapy have reported that the BIPAP machines are considerably noisier than CPAP models, which can be an influencing factor for many.

Typically, if a patient is unable to adapt to CPAP therapy, most sleep experts will recommend BIPAP treatment.

BIPAP Machine Features

BIPAP machine is a term that’s sometimes used when referring to a bi-level positive airway pressure machine. The BIPAP machine is a breathing device that can help the user to get more air into their lungs during sleep. This machine was created in the early 1990s and it’s derived from the continuous positive airway pressure machine (CPAP), however this model offers a more comfortable breathing experience than a CPAP device and it’s typically prescribed when CPAP therapy fails to work.

BIPAP Machine: How it Works

BIPAP Machine FeaturesThe BIPAP machine will use different levels of air pressure, instead of continuous air pressure like that of the CPAP Devices. Both types of breathing devices are prescribed for people with respiratory issues or sleep apnea.

CPAP devices work by providing a specific amount of air pressure which is transferred through a mask to the user. The set air pressure is designed to keep the user’s airways open. This will allow them to breathe easily during sleep. One common issue with this apnea device is that the user has to exhale against the air pressure. This is hard for many people to get used to and it can cause discomfort and sleep issues. Often, when a person is unable to get used to exhaling against the pressure the alternative will be to try a BIPAP machine.

Who can Use BIPAP Devices?

The BIPAP device will allow air that’s delivered via mask to be set at a specific pressure for exhaling and an additional setting for inhaling. This can make it much easier for the person to adapt to using this treatment and also allows people with neuromuscular disease to use this device. The dual settings will allow the user to get more air in their lungs.

The BIPAP machine is also more helpful for patients who are suffering from lung disorders or congestive heart failure. This is a great option for people who have had intubations or conditions that result in above average levels of carbon dioxide. Other people who can benefit from this treatment include patients who suffer from atelectasis. Atelectasis results when a lung partially or completely collapses.

There are a number of tests that your doctor can perform in order to determine if you would benefit from CPAP or BIPAP treatment. The FRVC test is an important test that can measure how deeply a patient can breathe. Sleep apnea can be diagnosed based on the findings of a sleep study. The sleep study will require a patient to spend the night in a facility where they will be monitored electronically and under surveillance while they sleep. The staff will be able to determine how frequently the patient stops breathing during the night while also determining the type of apnea the patient is suffering from.

The BIPAP machine will typically be covered by the patient’s health insurance, however it’s possible to also purchase a machine from a medical supply store. If the machine is too expensive.

medical supply stores rent them out on a monthly basis. If you think you may benefit from this type of treatment you should contact your neurologist of primary care physician.

Is CPAP a Better Option when BIPAP Devices Fail?

CPAP machines are also commonly used to treat sleep apnea. This device includes a mask or nose piece, a hose and a small machine. Common issues with this treatment include problems with the mask leaking, dry sinuses and difficulty falling asleep.

BIPAP Machine Features2CPAP is usually the first type of treatment recommended for sleep apnea. Should CPAP therapy fail, your physician will likely recommend using a BIPAP machine. CPAP is prescribed first because the CPAP machine is more affordable than a BIPAP.

If you’re prescribed a CPAP or BIPAP machine, be sure to work closely with your physician or medical supplier in order to find a mask that suits your needs and fits correctly. Everyone has different face shapes and needs, so the right size and style of the mask is important. There are a range of styles of apnea sleep masks available. This includes masks that cover the mouth and nose, full face masks and nasal pillows. A full face mask can make many users feel claustrophobic. A solution to this is a mask referred to as nasal pillows. This style works well if a person likes to read with their mask on.

Most masks come in different sizes that vary by brand, so it’s important that you try on a mask before you purchase.

In order to get used to treatment it can help if you practice wearing the mask for short periods of time, when you’re awake. Once you have become accustomed to this device, you can begin using the CPAP or BIPAP machine while you sleep.

If you begin to experience sinus issues you can purchase a device that also features a heated humidifier. Your physician can also prescribe a steroid nasal spray if the humidifier doesn’t work to prevent nasal dryness.
