2013年12月9日 · Alveoli are not larger in the apex versus the base. The apex of the lung has substantially reduced blood flow when compared to the base due to the effects of gravity. The apex has a higher V/Q ratio than the base. Alveoli are the same size in the apex versus the base, though the base is more compliant leading to the alveoli appearing to be larger.

2016年1月31日 · The effect of gravity at the apex can be interpreted as an additional collapsing force on the lungs. Not only do the alveoli want to collapse because of intrinsic properties, gravity is also pushing on alveoli at the apex, resulting in a greater collapsing force and a more negative intrapleural pressure.

2011年11月25日 · I tend to assume Sympathetic stimulation as fight-or-flight stimulation. If my assumption is true, then the blood vessels in the lungs should dilate during fight-or-flight (sympathetic) stimulation to increase blood flow through the lungs to supply enough oxygen to the body. Why is my thinking wrong or inconsistent with my school notes?

2025年2月5日 · You need to go back into your clinic and shout out the good news at the top of your lungs. Celebrate this! Reactions: olivecantaloupe , brynnapeddy , indysadventures and 4 others

2022年10月17日 · Congratulations on the options, especially this early. Would probably serve you better to ask in the Physician Scientist forum (or better yet, from mentors in real life rather than anonymous users).

2024年2月12日 · Health Cloud as a base layer can be negotiated down from list price to the 150-225 range per month and I guess in my case the cost of a pro account for zoom. At least from my information gathering. That plus the maintenance IT costs for wrangling salesforce updates to your complex integration plans, which I'm not entirely certain of just yet ...

2009年12月12日 · Only certain CVLs, ports, PICCs, etc., are certified for a power injector. I know that our CT techs will only inject through a central line as a last resort, and they do so with the full knowledge that there's a decent likelihood that they'll blow the line.

2004年3月15日 · I only remember my password to Lexicomp and it didn't give me too much detail as to the differences between forms except that it takes 400mg of erythromycin ethylsuccinate to equal the same blood levels that 250mg of erythromycin stearate or base produces.

2003年8月15日 · Listening to the lungs? Fine, go ahead, but if the patient is short of breath they are going to get an xray or cat scan anyway. Heart? Sure, but if they have a fever, they generally get blood cultures and if it persists they get an echo regardless of murmur. Abdominal? Useless except to find an acute abdomen, and even then it isn't that helpful.
