Observe for impaired circulation.
(a) Monitor the casualty's pulse and the color and temperature of the
limb distal to the splint. Also ask the casualty about numbness or tingling sensations if
he is responsive. Lower the air pressure if the splint is impairing circulation.
(b) Partially deflate the splint every 20 to 30 minutes to reestablish
peripheral circulation in the forearm and hand; then inflate the splint again to its normal
(3) Adjust for changes in environment by increasing or decreasing the
amount of air in the splint.
(a) Changes in the weather and temperature can affect the air
pressure inside the splint.
(b) Decrease the air pressure in the splint if the casualty is to be
evacuated by air.
