The improvised chairs mentioned in one of the previous post are called rehab chairs distributed through Morning Pride. The concept of forearm immersion has been around for a while, I believe the military has been using it for some time. Studies have shown that immersion of the forearm in cool or tepid water can drop the body temp by approximately 4 degrees F in about 10 minutes. We are waiting for some grant money to purchase them for each of our transport vehicles. I will update when they arrive.
