Long night, get to bed at 0430hrs.
0500hrs comes around, and our colleagues up in the communications centre have a great job lined up for us:
"Patients veins in hand swell up if hand is held below level of heart"
Now, dear read: please do exactly that: let you arm hand lowere than your heart, and you will realise that this is a perfectly natural occurrence. Something that has to do with gravity, apparently.
Not breaking any land speed records, we got cancelled on this call half way there. Which was probably good, because the second bit of information we got was "ambulance attended to patient recently. Patient has vast array of knives at home"
One step forwards for man. One step backwards for mankind.
