Cardiac Chamber Pressures And Monitoring Devices Explained Clearly!

In this video we will discuss the varying normal pressures within the cardiac chambers including the inferior/superior vena cava pressures, right atrial pressure, right ventricular pressure, pulmonary artery pressure, pulmonary capillary wedge pressure, left atrial pressure, left ventricular pressure, and aortic pressure. We will depict this in two different ways, both of which will hopefully make them easier to remember! Additionally, we are going to discuss the bedside invasive monitoring techniques that can be used to determine these pressures including central venous pressures with a central venous catheter and the pulmonary artery or Swan Ganz catheter measuring pulmonary capillary wedge pressure. We will spend a little extra time discussing the wedge pressure, specifically how it is taken to better grasp this tricky concept. Check out the video for all the details!

Cath lab tech in training here. This is super helpful, thank you. 🙏

Love to hear that! Awesome and important job!

We were taught the nickel, dime, and quarter system. RAP 2-6 ( about 5 ), wedge pressure a dime, ( about 8-12 ), and PA pressure a quarter over a dime 25/10. When I was a resident in the CCU, if the patient did not have a Swan, the Cards attending would say, " that patient has a yellow catheter defiency ! "
OMG, the memory's! I haven't put one in probably in 10 + years. CVP's are used usually now for vasoactive meds and blood draws; no longer pressure monitoring so much. I place preferentially L subclavian, but also IJ and, in extremis, femoral. We use a noninvasive NICOM device to measure cardiac output and stroke volume through bioreactance with 4 leads on the chest, and then determine fluid responsiveness, either through IV bolus or passive leg raise. If stroke volume increase more than 10 %, they are considered fluid responsive.
Good review. Brought back memories of old battles in the CCU, pre angioplasty for acute MI...the thrombolytic times.

That is all excellent! We are glad to have joined you on this nostalgic journey back to residency! Hah! Great nuggets of knowledge, per usual. I’m intrigued by this noninvasive bioimpedance device that can calculate stroke volume after fluid challenge?! Sounds very interesting

We were just thinking Hannibal. Not sure if this would at all be of interest to you, but given your experiences using MATH+ for COVID-19 patients, if you ever wanted to put a video together on your clinical experiences using these medications, thoughts on the various components, etc. we would be happy to post it on the channel! No pressure. Just something that popped into our head today as we were reviewing some of the recent comments. You could provide as much or as little detail on your professional background as you please. If interested, shoot us an email at [e-mail].

@@WhiteboardMedicine Would prefer to keep a fairly anonymous profile as my system is benign only to a point, and would not want to push too much as I am the only one using these treatments that I know of personally.

[@WhiteboardMedicine]

@@davidmbeckmann with our anonymous profile, we are of a very similar mind. Absolutely reasonable! We will continue to enjoy and appreciate your valuable contributions on all the various videos!
