Partial thickness (2nd degree) burns are characterized by specific symptoms that include pain, redness, and the presence of blisters on the affected skin. These burns affect both the outer layer of skin (epidermis) and the underlying layer (dermis).

The pain associated with partial thickness burns is due to the damage to the nerve endings present in the dermis. The redness arises from increased blood flow to the area as part of the body's inflammatory response, which is an essential process for healing. Additionally, blisters form as fluid accumulates between the layers of the skin, serving as a protective barrier that helps to prevent infection while the underlying tissues heal.

This set of symptoms helps to differentiate partial thickness burns from other types, such as full thickness burns, where the skin may appear dry and leathery and commonly lacks sensation due to nerve damage. By recognizing these characteristic symptoms, EMTs can assess the severity of burns effectively and provide appropriate care to patients.
