Internal medicine videos on Oxygen Hemoglobin Dissociation Curve and Medical Acid Base. A growing library on critical care topics such as Shock, Diabetic Ketoacidosis (DKA), and Mechanical Ventilation. Cardiology videos on Hypertension, ECG / EKG Interpretation, Cardiogenic Shock, Septic Shock, and heart failure. VQ Mismatch and Hyponatremia lectures have been popular among medical students and physicians.

NPs and PAs have given great feedback on Pneumonia Treatment and Liver Function Tests among many others. Dr. Jacquet teaches our FAST exam tutorial & bedside ultrasound courses. Many nursing students have found the Asthma and shock lectures very helpful. We're starting a new course series on clinical ultrasound/ultrasound medical imaging.
Recommended Audience - Medical professionals and medical students: including physicians, nurse practitioners, physician assistants, nurses, respiratory therapists, EMT and paramedics, and many others. Review and test prep for USMLE, MCAT, PANCE, NCLEX, NAPLEX, NBDE, RN, RT, MD, DO, PA, NP school, and board examinations.

I’m a LVN and i’m taking the prerequisites for the RN bridge program. My goal is to either be a ER or ICU nurse and then be a flight nurse. I’m glad I came across your channel. I’m watching them for the hell of it and I’m sure when I start the RN program, everything that I’m learing from your channel will come in handy.

Hi! May be possible to have a similar video regarding inotropes meds instead please? This one about vasopressors is very clear and perfect, it would be perfect having one about inotropes as well or even about the main differences between the 2 groups of drugs! Thanks a lot, I really love your videos!:)

you might want to switch to µg/kg/min as unit of dosing *all* continuous applied vasopressors instead of µg/min - because giving 20µg/min is different if you have a 40kg versus a 150kg patient. With µg/kg/min you can compare the need of pressor support between patients (and say: "gosh, that´s high, I need to consider other causes/actions"). I do see the problem that this is an institutional thing - if everyone is using ml/h (with various concentrations of pressors) and you´re the only one to use µg/gk/min (or gamma, as we colloquially call it) that might lead to problems in understanding...

Excellent! 1:52 "restrict blood flow to target end organs". n.b. Levophed, overused and often over-dosed will make you, as a clinician feel good about your patient's higher blood pressure, but.....blood pressure is never measured distal to arterioles where it would be indicative of blood/oxygen delivery (it's measured only proximal to arterioles in large vessels). So, a "good" blood pressure does not mean adequate oxygen delivery. Blood pressure is not cardiac output. Overusing Levophed gives a good blood pressure and no oxygen delivery....and kidney failure.....and "flash pulmonary edema" (which is code for: to much alpha-1)......and gangrene. Which is why it was nicknamed "leave 'em dead" years ago. DON'T overdose Levophed! Instead, titrate it to a diastolic pressure of 45 or so (for just-adequate coronary perfusion).
@Medcram
@Medcram Год назад
Preach it! This is why I tell the nurses to aggressively titrate down the vasopressors to get the map down to 65..

This is an great video for review of vasopressors & their mechanism of action. Question though... in my region of the country we administer all vasopressors weight-based, ie; mcg/kg/min. I my area of practice, I do encounter some pressors in mcg/min. That frustrates me, because I’m told by the sending nurse “They’re maxed out on Levo...” I get there and find them on 5 mcg/min of Levo and think to myself, “That’s no where near max dose...” Why is it that weight-based pharmacotherapy isn’t universal? Thank you so much for the FOAM.

My preceptor was so knowledge but i just couldn't understand his explanations and felt so intimidated by his knowledge and everything else going on with our pts as well. Did slowly learned them and stuck it out. Stayed for 26 yrs and justight come.back to ICU as I've enjoined having to push myself learn more. Can't explain it. I'll be watching more of your videos for sure. Thanks for explaining it where it is easy to comprehend. This will be helpful to so many med students and nurses at bedside, especially in ICU. 👍

Amiodarone... Where does this fit into things, please ?
@jamesclark4544
@jamesclark4544 4 года назад
Amiodarone is an antiarrhythmic drug, and is commonly used during certain cardiac dysrhythmias like persistent ventricular tachycardia, with and without pulses, and ventricular fibrillation. I believe amiodarone has a blocking effect on the calcium, potassium, and sodium channels in the (lower?) heart, so it works to slow down the ventricles..... ACLS has amiodarone as a push dose for pulses v tach and v fib, and has a drip dose rate for vtach with pulses..... As far as I know it doesn't have any effects on alpha receptors... that's all I know as a paramedic student lol!! Hope that helps :)
