She opens her eyes to voice, her skin is normal in color, respirations about 16 and unlabored, pulse 54 and a little weak at the wrist, with no external bleeding. She has flat neck veins, a normal chest and abdomen and a stable pelvis. First responders who arrived just before you, tell you that her pulse ox reading is 94 and her blood pressure is 74/30.
