Cardiac Anesthesia Techs
Curious to hear from other cardiac docs out there, particularly those who do their own cases without residents/fellows (or god forbid “cardiac CRNAs”)… What sort of tech support do you have? What sort of tasks do your techs so- set up drips? Place lines, or scrub in to facilitate? Help with any perfusion tasks? Check ACTs? Do they take call, and how much are they paid? At my shop we have CV anesthesia techs who set up all the drips, prep our art line kits, hook the line up and dress it... Read more (Source: Student Doctor Network)

Scared so much for Saturation
I am a freshman in college and I have gone through a lot this year. I found the PA profession and loved it (shadowed and everything). My school has a PA school attached to it so it is nice. Now I hear so much about saturation and NPs and how if 6-7 years, this field will become like pharmacy. Should I still do PA, or should I do something like optometry, PT, OT, or perfusion.

Why does 100% oxygen help patients with dead space but not pulmonary shunting?
Everything seems to make sense until you take into account hypoxic pulmonary vasoconstriction. For the sake of simplicity, imagine one entire lung has either dead space or pulmonary shunting and the other one is normal. In the case of dead space, the diseased lung will not have any perfusion. All that blood that is supposed to flow through that lung will flow through the normal lung. The normal lung will thus have 2x as much blood flowing through it. As a result, giving a patient in this... Why does 100% oxygen help patients with dead space but not pulmonary shunting? (Source: Student Doctor Network)

Ventilation/Perfusion question
This is from firecracker: "Pulmonary blood vessels constrict in response to low PO2, which decreases pulmonary blood flow to poorly ventilated alveoli and indirectly promotes blood flow to well ventilated alveoli. This hypoxic vasoconstriction is unique to the lungs, and helps maximize the efficiency of gas exchange." However, in areas of low ventilation, there is actually HIGHER PO2 in the alveoli. In areas of high ventilation, there is LOW PO2 in the alveoli. So how does this make any... Ventilation/Perfusion question (Source: Student Doctor Network)

low albumin and dec renal perfusion
Why does low albumin state lead to dec renal perfusion? I don't find this intuitive at all. Can anyone explain this? (Source: Student Doctor Network)

Ventilation and Perfusion Defects - Why one gets 100% O2?
Alright, I have listened to goljan a thousand times, veltillation defects do NOT improve with 100% O2, but perfusion defects DO improve (increase PaO2) with 100% O2. I have racked my brain and I can't figure out why, unless the ventillation defect is a total blockage, but then the person would be dead. Both result in a decrease in gas exchange, and an increase in the A-a gradient. Both have extra areas of the lung that are functioning ok, so why does giving 100% O2 to a perfusion...

PA or Perfusion?
Hello, I am just going to get to the point. I have over +8000 HCE as a pharmacy tech, Nuc Med tech, CT tech, and PET/CT. I have experience in the OR, Cardiology, Radiology, Pharmacy etc. I have my B.S. in Imaging Sciences as well as certs in Nuc Med, PET, CT, Pharmacy. My school history is the problem. I have some prior C's in a couple science courses (earth science, biology 1, Chem 2) and a couple other non science courses that I screwed up in early in my college career. However, my CUM and...

Why does Blood pressure important in low TPR?
This is the example: we have vasodilation (decrease TPR) in septic shock, the MAP will decrease despite of CO will increase (MAP=TPR*CO). So, we have high perfusion of tissues, because of arteriolodilation. So what is the problem? Why if we have decreased pressure (due to decreased TPR) it will cause problems like: syncope, low perfusion of tissues and etc? I really want to UNDERSTAND the importance of blood pressure in this situation (in the cases of low TPR=>high CO, low MAP). This my... Why does Blood pressure important in low TPR?

O2 diffusion in exercise and high altitude
During exercise and in high altitudes, is O2 diffusion still perfusion limited? As the equilibrium between Pa and PA is still eventually reached. Read somewhere that it became diffusion limited, but didn't agree, as to my understanding diffusion limited gases never equilibrate with alveolar partial pressure. Anyone could shed a light?

Perfusion, Midwestern. 2016 Cycle.
Hey guys, Since there is not anything about the cardiovascular science online. I thought that I might start a thread for those who are applying for the 2016 cycle. I applied 10 days ago and now I am waiting to hear from them for an interview. Has anyone applied to the program? (Source: Student Doctor Network)

Hyponatremia in Cirrhosis
I was thinking that since there is kidney hypo perfusion due to splanchnic vasodilation (hepatorenal syndrome), reduced filtration coupled with activation of the RAAS would lead to increased sodium concentration.. So how is there hyponatremia ? (Source: Student Doctor Network)
