And, right on cue, in steps the encyclopedia...
I seem to be making a habit of knowing the answers to peoples questions just recently! (And Carla always gives me such a warm introduction!)
Mottled Skin: Imagine a leopard's skin (but MUCH less severe!). It is where there are faint spots or patches on the skin. They can very in colour depending on what the cause is. Often red patches are caused by heat but it can also be a sign of an allergic reaction. Did the paramedics give you any other details?
Thats about as scientific as it gets really. Mottled skin is not life threatening, dont worry! I guess the paramedics are interested in case it was an allergy... but I could be wrong on that. (I am wrong occasionally... Despite what Carla might tell you )
All the best
Peripheral Perfusion really is just a posh word for the blood supply to the surface (in this case skin). Peripheral means outer or outside and Perfusion is the supply of blood to the capillaries in biological tissue. Sometimes you need a dictionary when you talk to paramedics and doctors... its like they talk another language. (Your lucky im nearly fluent! lol) If in doubt, google! It usually comes up with the right answer!
