Give me your opinions of what in the heck this was. Alright, dispatched to possible stroke. Once on scene, we find a male patient who is in his early 60s is sitting in a chair with all positive stroke test symptoms. BP 188/102, pulse 111 BPM, SPo2 89, Resp. 10 shallow light wheezing, blood glucose 90, skin is hot, slightly clammy with cold fingers on right side (same side as facial drooping), right pupil is fixed, patient is incontinent of urine, and patient responds to voice with grunts and will follow most directions- GCS: 11. Family members say symptoms started about 45 minutes prior to calling and that he hasn't wanted to eat or drink anything for approximently the last 36 hours so he's obviously dehydrated at this point. He has a history of hypertension and is allergic to nitro. Enroute to hospital, patient is given o2 at 2 LPM via NC and IO normal saline (IO instead of IV because no good vein access due to dehydration.) After a few minutes his BP just skydives down to 138/70, pulse 79, SPo2 100, resp. 15 normal. The facial drooping goes away, and he just sits up and says "oh hey fellas, what's up?" He is fine for several minutes then his BP drops to 88/52, pulse 48, resp. 32 shallow-which is the exact opposite of where we started! The facial droop returns, still awake, just doing the same as at first now. Then next thing I know, he's fine again. We get to the hospital and he is still fine until we get him in the bed and then everything goes back to how we first found him. Any ideas?
