Lung Recruitment

[soparu]

that's about the size of my lungs now.

word of advice: never work at a no name place. your organs might be sold

[thyda1000]

It's not normal to have half of your lungs being half, I am screwed!

Can anyone tell me the difference between PEEP and CPAP?

[Strummerville81]

@rimakala They are essentially the same, but PEEP is the pressure applied to the airways in mechanical ventilation during expiration to maintain alveolar recruitment. CPAP, in contrast, is a continuously applied pressure above atmospheric pressure (during inspiratory and expiratory phases). They have the same function: to maintain the alveoli open and improve oxygenation.

@Strummerville81 i may be mistaken and if i am i am sorry but when it involves both inspiratory and expiratory, isnt it referred to as bipap?

[Strummerville81]

@blooddudemagic biPAP is different. biPAP is a machine that delivers a biphasic breath strategy. You set an iPAP and an ePAP which are two different pressure settings with different purposes. CPAP is just one pressure delivered continously. When you exhale against this continous positive airway pressure, it has a "back pressure" effect that recruits collapsed alveoli and improves oxygenation.

[atomicdog2020]

@rimakala Simple explanation: CPAP is continuous pressure applied to spontaneous breathing. PEEP is pressure applied to ventilator breaths at the end of exhalation. Both "hold the alveoli open" and improve oxygenation.

Too much CPAP or PEEP increases intra-thoracic pressure and can decrease venous blood return to the heart. This will affect blood pressure and cardiac output.

holy shit wtf

[raccoon325]

Pumper!?

[pringlewrangler]

lol i wanted to see it explode!

[fotograh]

What lung species were used for this demonstration? And, is 15cmH2o the typical threshold of pressure to reach lung recruitment for a human lungs for optimal V/Q ratio?

[atiosextionio]

you start of with a PEEP of 5cmH2o

[KiddJonesJr]

depends on the disease process of the lung you are trying to recruit. but there is not a set number, say 15cmH20, that is the optimal PEEP. For each disease process is different thus there V/Q ratio or mismatch is going to vary.

i've got the feeling i shouldn't be here... -_-

[Charity17022]

That is SO gross, but so educational! Great job!

[ArminTheGman]

PEEP ZEEP GOOD VIID BUT STILL PEEP ZEEP xD sry had too

[maubin]

Hi George, nice work!

[6x10x23]

This 1 min post displays perhaps 2, maybe more, chapters on the effects of positive presure and PEEP on the pulmonary system not to mention the hours of study trying to conceptualize the whole process. I wish I had this to see a few years ago. It would have saved a lot of headachs. Great post

EXCELENT VIDEO!

THIS WAS GREAT!

[kevagonia]

good vid, thanks. explains well why peep helps to recruit alveoli and "pop open" more of the functional chambers of the lungs for more efficient ventilation.

[justmyworld74]

Thanks for sharing the video! Good illustration of PEEP. :)

[transparentreality]

well done, well done.

[amorgoo]

How can I download this cool video for my presentation

[rtstudent07]

Good way to give concepts of PEEP.

[vwgolfing]

I showed this to my respiratory instructor and peers. We love it.

[Bodereca]

This is amazing! I`ll show it to my students. Thanks.

[goose535]

what a great image for all RTs to have when setting up a vent and PEEP.  :)

[Marcus538]

This is why you start to see Rabbits smoking outside of their boroughs nowadays

[zobeckd]

Excellent...for all respiratory therapists and students

[danimarie37]

as an rrt, it was fascinating to see the effects of different levels of peep on these lungs.
