ETCO2 is directly proportional to cardiac output. no pressure = no CO2. period. if you saw tube pass cords, and are also sure tube didn't dislodge from time you removed laryngoscope and secured tube, there's really no other cause.

actually, you're incorrect. there is O2 reserve. it's called functional reserve capacity (FRC). in the anesthetized patient, or non-breathing and fully oxygenated patient, you burn about 3 ml/kg of oxygen per minute. so, in the 70 kg patient, you burn about 210 ml of oxygen per minute. now, the average FRC is about 2000-2500 ml, ideally full of oxygen. so, you take that number and divide by the 210, and you get anywhere from 9-12 minutes of "stress free" apnea. make sense? again, this is ideal, and not taking into account other stressors of the body. as wtbcrna stated, you have more time than one would think. the ICU is a different breed from the OR. and no matter what you've seen/experienced as an ICU RN, it pales to the CRNA and what we see on a daily basis. i'm not knocking it, i'm just saying.

so, nobody sees wearing scrubs (from the OR/hospital to the outside world i.e. public transportation, grocery stores, etc.) a public health risk/concern? there's more on scrubs after a day's work than changing a diaper, etc.. you all are misinformed and delusional to believe otherwise. if i was on the public health police force, i'd give any and everyone a summons for wearing scrubs when leaving the hospital. no reason for it. period.

it's not really that ironic

can you cite some "pretty well established" references? last i knew, you are held to the standards you are hired for. for example, if i'm a crna and work as an EMT-B, i can only perform those duties. so, i disagree.. it depends on the facility and role in which you were hired in. dino kattato crna

paper and reality are two different things. completely and wholly. do yourself a favor, and shadow a CRNA for a few days (at least), to see if it's remotely anything you like. please don't choose a profession based on paper, or you'll be utterly surprised and upset, etc...

uh, no. perhaps reference please?

uh, not sure where you were going with this, but depending on what your job role is where you're at, and what you're hired for, your scope depends on that, as well as liability.

1. no 2. depends, all bsn's are different. won't matter really when applying to crna school. if you want to stand out, take grad science classes if you must. 3. won't matter if you don't. if you do, do whatever makes you happy. 4. uh, if you can't get thru bsn, you might want to reconsider crna. you'll have much more trouble if you cannot get the gist of things based on your english understanding. sorry.

few thoughts arise from this: 1) potassium channels are inhibited by magnesium. hypomagnesemia results in increased efflux of intracellular K. the cell loses potassium which then is excreted by the kidneys, resulting in hypokalemia 2) magnesium is needed for the adequate function of the Na+/K+-ATPase pumps in the cells of the heart. a lack of it depolaries and results in tachyarrhythmias. since magnesium inhibits release of potassium, a lack of magnesium increases loss of potassium. Intracellular levels of potassium decrease and the cells depolarize, hence arrhythmias 3) roughly 42% of patients with hypokalemia also have hypomagnesemia, not responding to potassium supplementation hope this helps some-

in terms of history and the public, yes, it IS a physician designation. i don't know what this is supposed to mean. this is unfortunately argumentative. this is exactly the issue.

hey surgical hrt rn, in no way does one need ekg certification (which, imo, means nothing unless you even remotely become proficient in not only knowing the geography of reading an ekg, but knowing and understanding axis deviation, r-r', qtc, etc...) to work in the icu. what one learns in acls is more than adequate to recognize the two main lethal arrythmias, vt and vf. also, can you reference the legality of "reading" an ekg without certification? jcaho?? c'mon, they aren't even clinicians that run the commission, so i don't hold much water for them. and also again, even if you "read" the ekg, chances are the md will be making the ultimate decision. so, in short, i disagree with what you say re: 12 lead certification. dfk crna

with PPV (positive pressure ventilation), there's a difference in intrathoracic/intrapulmonary/intrapleural pressures. all these can/will affect true CVP readings. this differs in the patient who is (SV) spontaneously ventilating. there is less compression of vessels and more venous return in the SV pt, hence readings will differ.

your number one is partially correct. you do not need an MSN to further obtain a PhD. essentially any master's degree will/can get you into PhD program, provided you're a strong candidate.

:smackingf:yeahthat: of course, if you don't (want to) believe what others have said/are saying, maybe call the schools you are interested in. the AANA does not recognize LTAC as critical care. for the most part, any unit designated as an ICU is what they are looking for. rarely will ER or PACU be acceptable, but surely i haven't heard of ANYONE EVER getting admitted to anesthesia school with LTAC experience. my recommendation is get yourself to a sick ICU, surgical IMO, but ICU none the less.
