Yes, a tourniquet applied too tightly can cause petechiae, which are small, pinpoint red or purple spots on the skin resulting from bleeding under the skin. The excessive pressure can restrict blood flow and lead to capillary rupture, resulting in these spots. It is important to apply a tourniquet with the appropriate tension to prevent complications like petechiae and other injury.
It does work .... unless the wound is too high to place the tourniquet above it.
no longer than a minute and a half to two minutes once you get the needle into the vein you should tell the person to relax the fist first then remove the tourniquet if left on too long you can obliterate the blood supply and cause tissue damage
Place a tourniquet above the injection site and apply heat
When applying a tourniquet, you should place it approximately 2 inches above the wound, with enough pressure to stop the bleeding but not so tight that it cuts off all circulation.
The torniquet is a last resort. Using a tourniquet is likely to result in the loss of a limb. First you have to try direct pressure, elevate the wound, pressure points, and maybe using a hemostatic agent to stop the bleeding. If all else fails then use a tourniquet. A tourniquet is used most of the times in conjunction with a bandage and a dressing.
a solid
you place it on and secure it tightly
The state of matter that is held tightly in place is in the form of a solid. Gas particles are not tightly packed, unless they are being pressurized, same with water.
Solid
what is the maximum amount of time a tourniquet should left on
Typically, painting is done on a "canvas" which is not only tightly woven but tightly stretched on a wooden frame and securely tacked in place.
The best way to store art paintings is by storing them in a dry cool place. The heat will cause it to discolor. One can also wrap them in bubble wrap not too tightly and keep in a dry place.
