Ok....Because I have not yet performed CPR on an actual human being I wanted to know how I would know if my compressions were adequate to facilitate circulation? This is one of our open book questions and Im not sure if there is even a way to know this. I know that correct rate rhythm and depth are essential.

If someone is able to ascertain a pulse while you are providing CPR that would be the best way. Particularly if they were able to feel lower pulses such as radials, femorals and pedal. Also make sure there is a firm surface underneath the patient's back to push against. I suppose if the person had a urinary catheter in place and you had a long code going on, another sign would be the presence of continuous urinary drainage filling the bag. Means the kidneys are being perfused, so you know that the brain is as well.

That is really interesting....So if CPR were being performed on a patient that had a foley, and doing it correctly. You would see urine filling up the foley bag.

That is unlikely, and definitely not how I would assess my CPR effectiveness. The presence of a palpable pulse, or in a critical care environment the arterial line trace is the best way to measure effectiveness.

Again though only in the long run, not an immediate thing you would see. The main things are assessing the pulses.

Poahbear, I always teach that any compressions are better than no compressions, as long as the position is correct you will be making some impact. Feeling a pulse during compressions is one way of knowing if you are perfusing the organs and this will let you know that the compressions are doing that. It is also important to bear in mind that efficiency of chest compressions reduces with rescuer fatigue, you should be looking to change the person doing the compressions reguarly, I make a change at least every cycle which is almost a trigger to change as there are other things going on at that point.

There has been some research done on fatigue during chest compressions but I can't recall the references, let me do a bit of digging around to see if I can find it.

Thanks everyone,

Im almost done (May 16th) and I feel sometimes like I dont know everything Im supposed to know. There is soooo much. Im hoping it will all come together once Im on the floor

Heh heh Poohbear.... I don't think that feeling will every change...
Congrats on your impending graduation!

You will see this on the cardiac monitor. You should feel a pulse with every compression. Also it will look on the cardiac monitor like you have a wide abberant rythym (if in asystole and not in PEA). Mostly if you FEEL it.... It's good cpr.

Hi mate Am Bader BLS instructor the answer for ur question might be already given to u but i just wanted to emphesize on 2 important things which u have to keep in mind.
1- if u were doing chest compression hard eoungh u will see the ECG Rhythm in the monitor attached to the patient or the victim is wide and steady maintaining remember 30:2 5 cycles with complete chest recoil to improve the circulation.
2- while u r doin the compression the second rescure is checking the Carotid Pulse looking for good pulse with a good volume and he/she will till u to press harder and so on.
