What is the proper hand and body position for performing CPR?

The proper hand and body position for performing CPR is critical for delivering effective compressions. When the shoulders are directly above the animal's body and the fingers are interlocked, it allows for maximum power and leverage. This alignment helps to ensure that the compressions are delivered straight down into the chest, which is essential for generating enough pressure to circulate blood effectively.

In this position, the rescuer can use their body weight to assist with compressions, minimizing the risk of fatigue during the procedure. The interlocking of fingers also helps to stabilize the hands and avoid slipping during compressions, which is vital for maintaining consistent depth and rate, crucial elements in successful CPR.

Other positions such as having elbows bent at a 45-degree angle, relaxed shoulders with arms hanging down, or back arched with knees on the ground do not offer the same mechanical advantage or control over the compressions. These postures may lead to ineffective compressions, increasing the risk of failure to circulate blood adequately. Therefore, the ideal hand and body position is essential for the effectiveness of CPR.
