To apply digital pressure for severe bleeding from an open wound on the thigh, you should use what part of your body?

Using your knee or the heel of your hand to apply digital pressure for severe bleeding from an open wound on the thigh is effective because these parts are capable of exerting significant pressure over a larger area. The heel of your hand provides a firm surface, allowing for controlled and sustained pressure directly onto the bleeding site, which is crucial in managing hemorrhage by promoting clot formation and minimizing blood loss.

When applying pressure, it's important to support the limb adequately to ensure that the pressure is concentrated over the wound rather than simply compressing the surrounding area. Using your knee can also offer weight that enhances the effectiveness of the pressure, particularly if you are applying it while kneeling next to the patient. This method is preferred in emergency situations because it allows you to maintain pressure while freeing your hands for other life-saving measures, such as bandaging or calling for help.

The choice of not using your fingers or palm is due to the limited surface area and lower pressure they can apply, which might not be sufficient to control heavy bleeding effectively. The elbow and knee, while capable of applying pressure as well, do not offer the same degree of control and manipulation that the heel of your hand provides when positioned correctly. Therefore, employing the knee or heel of the hand ensures that
