As we speak, the healthcare industry is on the verge of a major transformation. The explosion in digital technologies means that doctors are now able to access patient records from anywhere and everywhere. However, not all medical professionals have been trained to use these advanced tools so it’s important for you as an individual to understand what type of doctor you need at this time.

The “what must you do” is a question that has been asked many times. The difference between what you need and what you want to do will be explained in this blog.

What is the difference and what do I need?

CPAP vs BiPAP airflowBiPAP and CPAP are both used to treat various health issues.

What’s the difference between CPAP and BiPAP, and what do I need?

What’s the difference between CPAP and BiPAP, we’re often asked. There are many distinctions between them, both in terms of how they operate and the diseases they are used to treat. Here’s our guide on CPAP versus BiPAP, which can help you figure out which one is ideal for you.

What I actually want to know is: what do I require?

The short answer is that it depends on your medical condition and the intensity of your symptoms – and, more significantly, it is not a choice you must make. You must have done a sleep test to utilize either option. Your sleep specialist will use the findings of the test, as well as any other relevant medical variables, to determine if CPAP or BiPAP is the best choice for you. You may get a sleep test online right now if you haven’t already.

So, what exactly is CPAP? Here’s all you need to know about it.

Continuous Positive Airway Pressure (CPAP) is an abbreviation for Continuous Positive Airway Pressure.

Fixed-pressure and automated CPAP devices are the two kinds of CPAP machines available. A fixed-pressure machine maintains a constant pressure, while an automated determines how much pressure you need at any given moment. 

The “pressure” we’re talking about is provided by the CPAP machine gently expanding your airway, preventing it from shutting or getting blocked, and stopping you from breathing (an “apnoea”) as you sleep.

Your sleep clinic, or potentially your doctor, would be able to give you with this pressure setting. These are calculated for your needs depending on a number of variables. If your clinic or GP has prescribed a fixed-pressure setting, then a fixed-pressure machine should suffice. Automatic CPAP devices, on the other hand, have grown significantly more popular in recent years.

CPAP vs. BiPAP (Automatic CPAP Machine)

If you don’t have a particular pressure setting (which most people don’t), you’ll have to go with an automated machine, also known as APAP (wrongly, see below for a boring explanation). Automatic machines are equipped with a variety of sensors that enable them to compute the amount of pressure you demand at any given moment. When it detects that you are about to stop breathing, it boosts the pressure (air pressure) and then drops it after the danger has gone.

This means you’ll receive less pressure on average throughout the night than you would with a fixed pressure machine set to the higher level necessary. As a consequence, many people find the treatment to be more pleasant and beneficial.

You’ll need an Automatic CPAP Machine if you haven’t been prescribed a fixed-pressure setting (for example, 12cmH2O).

Why is the word APAP technically incorrect? “Continuous Positive Airway Pressure” is what CPAP stands for. The “Continuous” portion of CPAP should not be removed since an Automatic machine still produces continuous pressure, but the amount of that pressure adjusts as needed — it never stops. Automatic CPAP or Auto-CPAP is the proper term.

What is the difference between BiPAP and CPAP? BiPAP vs. CPAP

A BiPAP machine performs the same basic function as a CPAP machine: it increases airway pressure by forcing more air into the airway via a mask and tube.

A BiPAP machine, on the other hand, may offer a significantly lower degree of pressure when you exhale, making it much simpler to exhale.

The “Bi” in “BiPAP machine” refers to two different pressure settings. When breathing in, it’s higher, and when breathing out, it’s lower. IPAP (inhale) and EPAP (exhale) pressures are the abbreviations for these pressures.

They may switch between the two settings “on the fly” depending on your breathing, or on a “timed” basis, with the machine assisting in breathing regulation. As a result, BiPAP devices commonly contain the letters “S”, “T”, or “S/T” in their names to indicate whether they utilize spontaneous pressure switching, timed pressure switching, or a mix of both. We go through this in further depth below.

What’s the point of having two pressure settings?

Some more severe or complex conditions, such as chronic obstructive pulmonary disease (COPD) or emphysema, may reduce lung function and make breathing out against a CPAP machine difficult. When breathing out, a BiPAP may dramatically reduce the pressure, making it more easier and more pleasant.

While traditional CPAP delivers little to no pressure drop while breathing out, most individuals are able to acclimate to this and still have enough strength to exhale comfortably.

Some health disorders, such as Central Sleep Apnoea, may cause erratic breathing cycles, and a BiPAP T device’s “timed” pressure switching can assist patients maintain their breathing regular and constant. A “spontaneous” machine, on the other hand, is typically the best alternative.

When comparing BiPAP with CPAP, the second major technological difference is that BiPAP may provide higher pressure than CPAP. A BiPAP machine can often provide up to 25cmH2O, but a CPAP machine can only deliver 20cmH2O. As a result, BiPAP devices may be advised for patients who need greater pressure than a standard CPAP machine can deliver to avoid apneas.

As previously stated, the findings of your sleep test will help your sleep expert determine whether you need CPAP or BiPAP and if you have a medical condition that might benefit from BiPAP’s technological benefits over CPAP.

Who is a candidate for BiPAP therapy?

  • Patients with sleep apnea who have high-pressure settings or low oxygen levels are often administered BiPAP devices.
  • BiPAPs are often utilized when CPAP has failed to successfully treat specific individuals.
  • Patients with cardiopulmonary diseases, such as congestive heart failure, may benefit from BiPAPs.
  • People with respiratory problems or certain neuromuscular abnormalities are often administered this medication.

Key Differences Between CPAP and BiPAP

To summarize the differences between CPAP and BiPAP,

  • BiPAP might have a second, considerably lower pressure for breathing out, while CPAP offers constant pressure throughout both inhalation and exhalation.
  • A BiPAP machine may provide higher pressure than a CPAP machine.
  • A “timed” pressure switch on BiPAP T devices may assist control breathing.
  • BiPAP is often utilized for people with more complicated health issues than “basic” Obstructive Sleep Apnoea because of the distinctions.
  • You do not need to choose which option is ideal for you; your sleep expert will do so depending on the results of your sleep test.

CPAP vs. BiPAP: What’s the Difference?

Please contact with your doctor or a sleep treatment professional before attempting to acquire a CPAP or BiPAP machine to establish your condition and what you truly need. It is not your choice to make, so don’t waste time studying and worrying about it!

If you’re new to OSA therapy, don’t be alarmed; it’s more common than you would believe, and you have numerous alternatives. There’s no need to worry about CPAP vs. BiBAP or “what should I purchase to obtain the best treatment?” since the experts who evaluate your sleep test will know and will advise you properly.
