Intermittent infusion is used when a patient requires medications only at certain times, and does not require additional fluid. It can use the same techniques as an intravenous drip (pump or gravity drip), but after the complete dose of medication has been given, the tubing is disconnected from the IV access device.
The Air Max 90 has become quite the icon since itâs debut in, er, 1990. It was the second running shoe created by architect-turned-trainer-designer (sure) Tinker Hatfield, displaying itâs air bags for all and sundry to see (a bit like the Le Blow gals on a night out).
