I know this sounds ridiculous, but in nursing school I was able to take manual blood pressures on the dummies at school. Now that I am working on the Cardiac floor...I have to take A LOT of manual blood pressures because a lot of my patients are Hyper and Hypo tensive and the machines will not pick the readings up. I feel like such an idiot but does anyone have any tips? After Im off orientation I dont want to have to go get other nurses to do a manual on my patients!!! My problem is I just cant hear anything at all really...Thank You!!!
