That all being said, it is a very difficult mode to run because you must keep in mind that changes being made to benefit ventilation or oxygenation usually inversely affects the other.

@rbonawitt

brilliant way to put it!!!!

[lifenowadays]

Dr Hanashi would destroy this! LMAO These are the worst APRV setting ever.

@lifenowadays

its for teaching purposes. Oh and its Habashi, if your going to criticize someone quoting a study make sure you at least know how to spell the name of the study.

With all due respects you did a poor job, at best, describing APRV. Mechanical Ventilation is a serious subject and you should not be releasing erroneous information that could misguide someone. Anyone looking at this video should do a simple google search on APRV and read just the first three articles to get a better understanding of how this mode works. Please do some research and update this video. The setting you show is a clear indication that you don't know this topic.

dude anyone looking for official clinical information SHOULD NOT be using youtube. a person asked me to do a very basic breakdown of aprv. This video stays, because it is for LAY non medical people. If you are out raged and think Dr. Habashi would freak out because i was trying to show someone his mode in terms they would understand without knowing the intricate system of factors that compose the ventilator mode then you are simply stupid, i know plenty like you that arent happy until complainin

It also should be noted that starting with a Plow of 0cmH2O is beneficial to allow for a maximum exhaled tidal volume as a result of the change in pressure from Phigh to Plow. It can result in higher PaO2 levels mainly by the major increase in mean airway pressure as a result of the inverse I:E ratio. Bi-Vent is beneficial because it can sustain PaCO2 and PaO2 levels with lower peak pressures, thus making it less stressful on the lungs.

[rbonawitt]

Bi-Vent is a mode of ventilation usually used on very critical patients who’s PaCO2 and/or PaO2 levels can’t be sustained with conventional ventilation modes (even with extreme settings such as; RR resulting in 1:1 or even inverse I:E ratio, high levels of PEEP, and peak or plateau pressures > 35cmH2O). It can result in lower PaCO2 levels in 2 ways: allowing for spontaneous respirations at both Phigh and Plow levels and the change in pressure between Phigh and Plow.

poor poor; get rid of this video as it is mostly erroneous info

APRV is; if effectively setup, with lower pressures and an extended Hi Time for recruitment and improved FRC, which will help improve the PaO2 with lower requirements for FiO2. The volumes are considerably lower with APRV than conventional ventilation and you are not creating more stress on the lungs because it is a more supportive mode. Maybe an easier way to explain this would be a pHi (high level of CPAP) set for a time High, with no PEEP at the time Low. Spontaneous breathing is encouraged.

[AllforKJ]

J.R. Just a quick response; not to be critical, just to encourage you to keep studying and researching for accurate information concerning APRV. It is evident you were only giving what you have been told or read on the subject. Your statements: 1. APRV puts a lot of stress on the lungs due to higher pressures. 2. You'll get higher volumes with the higher pressures. 3. You'll have a lot higher FiO2. 4. APRV is a lot more supportive and stressful. All 4 statements are inaccurate.

A good short video. Not sure who you are, Ventguyrrt, but you're clearly trying to inflame, and overstate your understanding of ventilators. You are *exactly* the type of RT we fired in our unit.
