Actually, when I think about it, watching paint dry might just provide a bit more satisfaction than watching IVs. When the paint is dry, that bit of the renovation is complete and you can move on to a new room. In the case of IVs – one is simply replaced by the next in line, and the next, and the one after that. Whether it is blood, platelets, calcium, magnesium, potassium, immune suppression drugs, antibiotics or solution-du-jour – the little boxes attached to the IV pole modulate the flow and seem to announce a change rather loudly. That change, completion or “air-in-the-line” of course is most likely to happen in the few minutes between interruptions that might possibly have been intended for a nap.
