Lung Recruitment

Animal model (rabbit I think) of a lung ventilated at different levels of PEEP (0 cmH2O - 15 cmH2O) and the recruitment and derecuitment that occurs.

I believe this comes from Dr. Slutsky's lab in Toronto.

@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.

that's about the size of my lungs now.

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

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

@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.

@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]

@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.

Can anyone tell me the difference between PEEP and CPAP?

[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.

holy shit wtf
