Offlabel / Clearly understood. Thanks for your advice!

Hello all. I am working in MICU and also studying critical care nursing. As far as I know, It's a trend that PA catheter is not used anymore as much as it used to be in the past. But my question is, when you study cardiovascular chapter in the books, a large proportion of contents still covers hemodynamic parameters which can be obtained by PA catheter. (PAOP, Pumonary artery pressure, PAd, PAs, etc.) So I am kind of lost how much I should put my efforts into this topics. (I know I need to study hard but I don't think I can digest all the stuffs without some efficiency!) Thank you so much for reading this.

I've heard this terrible story about an error an RN made ; a medication injected into EVD line, which was supposed to be given IV. And You know what happened. This alleged stupidiest error still gives me chills

I'm not sure this question is to be on this category. I am studying the respiratory physiology, and this statement is making me disturbed. 'If there were not surfactant secreted by type2 cell of alveoli, the alveoli will be collapsed. Because of the increased surface tension.' from above sentence, I know what the surfactant is, what it does but I wonder how increased surface tension makes alveoli collapsed. I mean, from physical point of mechanism. When alveoli collapse With increased surface tension, do they just tear apart? Like balloon? It would be very thankful if you give physical explanation of collapsing of alveoli

Vandydani / thank you very much for your detailed explanation first! But I don' get it still especially the part 'the pleural pressure is negative so it makes lungs open'... maybe I should check the whole respiratory mechanism?

God.. thanks you two flyingscot and vanilla bean. haven't thought of functional hemo and non functional hemo... it was really helpful! Oh and flyingscot, link 18285 attachment doesn't work

hi I am a nurse on ward. I was just looking through thoracic cage anatomy And this sentence needs to be understood to me. "subatmospheric pressure in pleural space is responsible for continued expansion of lungs" you can just explain it to me or suggest any link that may help. thanks for your attention.

thank you first. will read anyminute!

still struggling here. but thanks for the link.

then this statement is false? SpO2 stands for Peripheral capillary oxygen saturation. It is an estimation of the oxygen saturation level. I think it can be said that p stands for pulse oximetry (Just for convenience maybe?) not peripheral capillary...

Hi. I am a nurse on ward. straight to the subject, I am looking through books to study o2 saturation and this thought just popped up in my head. a pulse oximetry is used to measure SaO2, while the clip is applied to the patient's fingertip,right? So the question is,how the pulse oxi measures arterial blood gas when there's no artery at fingertips? quite a dumb question huh? Help

Does that mean I have to register for another school or college? I mean it's a bit frightening to do so.. lots of courses and financial matter and all.. Is there more of a less-time consuming and cheaper way to get it? Like the one that you can attend just 4 hours per week for one course...or online course if any? I really want to add some As, but don't want to get another whole bachelor degree

Before the start, I want to apologize to you because I know this kind of topic is annoying to some of you. But I searched and scanned here like 2-3hours. there's no answer that satisfies me. so getting to the point, I'm not a U.S. citizen, but a foreigner who's willing to be and currently serves as a military nursing officer. I'm really interested in CRNA and some other further degrees, but my past BA GPA is so bad, which is barely below 3.0/4.5... and I know most of special courses require a GPA above 3.0 or higher. Can you give me an advice? please help me. I would be really grateful. God bless you
