There are first aid steps you can take after a snake bite occurs, such as cleaning the wound, remaining calm, and immobilizing the affected area. However, it is essential to get the bite victim to a medical facility immediately for emergency treatment.If treated in time, the outlook for recovery is good.here are first aid steps you can take after a snake bite occurs, such as cleaning the wound, remaining calm, and immobilizing the affected area.

What it tests. The amount of shoulder external rotation, assessing the capsule and joint (to allow passive motion) and the posterior cuff (to power active motion) How to do it. Stand in front of the patient. Ask them to keep their elbow at the side and point their hand at you (in gunslinger pose). Have the elbow flexed at 90. Ask the patient to externally rotate the hand as far as possible with the elbow held against the trunk. Repeat this assessment with passive motion and compare.
In the diagram, the angle is the angle right hand rule, which gives a vector out toward the reader in this case. Note that the torque is maximum when the angle is 90 degrees. A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force.The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.The direction of the torque associated with the illustration above is toward you. That is, it is along the rotation axis in the direction out of the screen.he lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.
