On the HUD in Splatterhouse (2010), one of the attachments is the Health Meter. It is the thinner blue bar attached to the heart.

If Rick is injured by a creature, part of the Health Meter will decrease. Rick will also show signs of physical injury, such as deep gashes on his body, and even the dismemberment of one of his arms.

The player can refill their health meter by using the Splatter Siphon ability.
