    BiPAP Machine

    BiPAP, BiPAP ST and AVAPS Overview

    BiPAP machines provide two distinct pressures. The higher pressure is needed for inhalation, while the lower pressure in need for exhalation. The lower pressure is intended to help you breathe out against the pressure of the machine. In addition to providing two pressures, BiPAP ST machines are designed to initiate a breath which ensures you are receiving the minimum breaths per minute. AVAPS machines gradually adjust to match your current breathing patterns to your target tidal volume of airflow.

    BiLevels & BiPAPs FAQs

      What's the Difference Between BiPAP and CPAP?

    Here's a quick definition that can explain the differences between CPAP and BiPAP (or BiLevel) Machines. The most significant difference between the two machines can be summed up like this:

    CPAP Machine: A CPAP machine only delivers therapy air to the patient at one specific pressure and doesn't vary unless manually changed

    BiPAP Machine: A BiPAP machine uses two different pressure settings. BiPAP therapy pressures are usually higher for inhale, and lower for exhale. The lower pressure on exhale can make it more comfortable to breathe out.

    The ability to deliver therapy air at two different pressures makes BiPAP stand out from CPAP machines, as well as having the ability to provide therapy pressures above 20. It's wrong to think of BiPAP machines as being "better CPAPs," and only consider the differences in pressure. Some BiPAPs can be used to treat Central Sleep Apnea and can prompt breathing if stopped. The best Sleep Apnea treatment isn't a question of “what works better?”—it’s a question of individual fit, based on individual needs. If you think BiPAP could be right for you, you will need to talk to your doctor.

    CPAP therapy is the usual treatment for Obstructive Sleep Apnea. Certain health conditions compromise breathing and lead to an imbalance in blood gas levels. There may have too little oxygen in the bloodstream or too much carbon dioxide. For people with these types of pulmonary conditions, BiPAP might be the better treatment option because it addresses the other breathing-related issues, as well.

    Here are some benefits to using a BiPAP:

    • Using a BiPAP machine can make breathing much easier than a CPAP. With a lower pressure on exhale, breathing out becomes easier and more comfortable. If it's easier to exhale, it can mean less carbon dioxide gets breathed back in, and it's less likely to create higher levels of CO2 in the blood. Only a doctor can know if higher CO2 in the blood is a problem-- if this feature is needed at all.
    • Some BiPAPs can prompt breathing if the machine notices the user hasn't taken a breath in a while, a feature that CPAP and APAP machines don't have. Prompting breathing is great for patients that suffer from Central Sleep Apnea, and occasionally don't get signals from the brain to breathe.
    • BiPAPs are great for people with certain respiratory conditions that require assistance inhaling and exhaling.
    • BiPAPs can also deliver therapy air at a higher pressure setting than 20 (which is the limit for CPAP and APAP devices)
      What is VPAP?

    A VPAP is not the same thing as a BiPAP. The two are very similar in how they work, but the main difference between a VPAP and a BiPAP lies in how the pressures for inhale and exhale are selected. Like a BiPAP, the VPAP uses a higher pressure for inhalation and a lower pressure for exhalation. While a BiPAP is preprogrammed with two distinct pressures for inhale and exhale, the VPAP is an auto-adjusting bilevel breathing device. Unlike a CPAP, which provides continuous flow, the VPAP machine studies your breathing and chooses the correct pressure based on individual therapy needs. VPAPs can treat Sleep Apnea, but can also treat other pulmonary and lung diseases as well.

      What is the difference BiPAP and BiPAP ST?
    A BiPAP (also referred to as a BiLevel or VPAP) delivers two set pressures, a higher pressure for inhalation and a lower pressure for exhalation.

    BiPAP and BiPAP ST machines are similar, as they are both designed to provide the same airway pressure. The difference between a BiPAP and a BiPAP ST is the Spontaneous Timed feature. The ST responds to the user when the minimum number of breaths per minute has not been met. This machine ensures all breaths occur by triggering the user to take another breath within the minute.

    For example, a BiPAP might be set at the following:
    • Inhalation Pressure - 10
    • Exhalation Pressure - 5
    In this case, a BiPAP will provide an IPAP of 10 and EPAP of 5.

    A BiPAP ST might be set at the following:
    • Inhalation Pressure - 10
    • Exhalation Pressure - 5
    • 12 BPM (Breath Per Minute)
    Similarly to the regular BiPAP, the BiPAP ST will provide an IPAP of 10 and EPAP of 5, and will additionally monitor if you inhale 12 times within the minute. Please Note: The ST will not breathe for you, rather it will prompt the user to take a breath.
      What is the difference between Bi-Flex and C-flex?
    C-Flex only works at the start of an exhale. Bi-Flex works during the transition from exhalation to inhalation, the transition from inhalation to exhalation and during exhalation.

    Did You Know?, BiLevels & BiPAPs

    • BiPAP stands for BiLevel Positive Airway Pressure.
    • BiPAPs have two pressure settings, one for inhale and one for exhale. This makes exhaling significantly easier.
