I had read a post a while back on useing the cuff to take BPs in survival situations and it seemed strange to me to rely on the equiptment in a survival situation where it may not be available. I work in the medical field and had learned several years ago how to take BPs without a cuff and realized most people may not know about it so thought it would be good to share. You take the pulse in the right curotic arterey and the rate per minute is the sistolic then take the pulse on the left side and the rate there is the distolic. It should always be within about 2 points on each of what you would get with the cuff. This can come in very handy if the arms are to messed up to be able to do anything there or if you dont have a cuff.
