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).
So with all that said, agonisingly wrestled down from a long, long list of favourites, here's my take on the 20 best sneaker designs ever â and note, these are not in order! 01. Nike Air Max 1. The Air Max 1 wasn't the first shoe to use Nike's technologically advanced air cushioning system. That honour falls to trailblazers like the Tailwind, the almighty Air Force 1 and 1982's Air Ace. However, 1987's Air Max 1 was the first to bare its innards to all with its 'visible air' window.
