What is CPAP?
Continuous positive airway pressure or CPAP is a type of positive airway pressure kind of ventilator. This applies mild air pressure and that on a continuous basis so as to allow your airways to remain continuously open. This is in those individuals who are unable to breathe in a spontaneous way on their own.
What is BiPAP?
BiPAP (also known as BPAP) is Bilevel Positive Airway Pressure. It is really similar in function as well as design to the CPAP machine. Like the CPAP machine, the BiPAP one tends to be a non-invasive type of therapy used for those patients who are suffering from sleep apnea.
When looking at both machine kinds, they give pressurized air via a mask to your airways. The air pressure allows the throat muscles not to collapse and reduce obstructions by behaving like a splint. CPAP and also BiPAP machines let patients breathe easily and also regularly across the night.
Why is BiPAP different than CPAP?
CPAP machines mainly have been a popular treatment to handle obstructive sleep apnea. A CPAP machine is able to deliver a steady and continuous stream of required pressurized air to your airways so as to stop them from collapsing and leading to apnea events. When you get a CPAP titration study done, the sleep technician plus doctor will figure out the pressure settings for the CPAP machine. They will set the machine to give the exact amount of pressure needed continuously.
A CPAP machine is only able to be set to one pressure which stays consistent across the night. But, many CPAP machines possess a ramp feature which begins with a lower pressure type of setting then gradually builds going to the prescribed pressure. With this comfort feature, the pressure at the beginning stays more tolerable and also less immediate, once the required pressure builds going to the needed setting. This then remains at that setting across the night.
The main difference present between BiPAP as well as CPAP machines tends to be the point that BiPAP machines possess two pressure settings, i.e., the prescribed pressure needed for inhalation or ipap, moreover a lower pressure needed for exhalation or epap. The dual settings let the patient get more air in as well as out of the lungs.
What is PEEP?
This is an alternative to positive end-expiratory pressure or PEEP. When looking at these, both modalities are able to stent your lungs’ alveoli open, therefore recruiting more of your lungs surface area, particularly for ventilation. However, PEEP refers to devices which impose positive pressure only specifically at the end of your exhalation, CPAP devices are able to apply proper continuous positive airway pressure across the breathing cycle. So, the ventilator by itself will not cycle during CPAP, and there is no extra pressure higher than the level of CPAP that is given. Moreover, patients will need to initiate all their breath.
What is the difference between PEEP and CPAP?
CPAP is continuous positive airway pressure whilst PEEP is positive end-expiratory pressure. In CPAP, there is the word continuous. This means that the air is always getting delivered. When looking at PEEP, the air gets delivered only at a certain time, i.e., the end of the “expiration” or breath.
Despite this, the two terms are usually used like they mean one thing. This can be confusing. PEEP rarely refers to CPAP technology. This is at least not in those terms meant for the condition of sleep apnea. Unlike CPAP, whereby the air gets delivered constantly through a machine, PEEP usually refers to air which is manually delivered and that by the manual resuscitation bag or MRB.
CPAP and PEEP tend to be really similar therapies. In both techniques, it is aimed to prevent one’s airway pressure from actually falling below the minimum level. The therapy is known as PEEP when the patient will be on a mechanical ventilator. When the patient is breathing in a way that is without any help from a ventilator, then the therapy is known as CPAP.
Most references to PEEP tend to be for clinicians. PEEP is usually employed to refer to a kind of setting and synchronization which is part of setting up the CPAP device. PEEP is mainly the concern of doctors as well as nurses who are responsible for setting up the patient’s ventilation systems. It is not something that patients need to be worried about who need to employ CPAP to handle their sleep apnea condition.
