Okay here's the situation... You get called out for a 20 y/o female who has passed out they think from overexertion. You arrive and there is a person administring first aid, trying to get the pt. to respond. She has squeezed his hand, he reports to you, but that has been the extent of her response. She was playing broomball, felt tired, then when they tried to move her to get her inside, she went limp. They moved her inside and laid her on the floor which is where she is now. She is soaking wet, and freezing cold. (It is -10C/10F outside.) Whole body is rigid. They have people rubbing her extremeties, and have warmed blankets covering her. Just after you get there, she goes limp, completely, 100% limp. Breathing goes to almost nothing, very shallow breaths every 10-20 seconds. Radial pulse-nonexistent. Carotid pulse-very weak, irregular 35 bpm. B/P-86/44 They are able to tell you that she has suspected heart murmur and that she has passed out from overexertion about three months ago, but it wasn't the same as this time. Action plan? What are your tho'ts?
