Definitions:

Ineffective Breathing Pattern

A respiration problem where an individual's breathing is not sufficient to support optimal gas exchange.

Incisional Pain

Pain that occurs at the site of a surgical incision, often experienced after surgery as the wound heals.

Shallow Respirations

Breathing that is abnormally rapid and not deep enough, potentially leading to decreased oxygen intake and buildup of carbon dioxide.

Anesthesia

Medication used to prevent pain during surgery by causing loss of sensation or consciousness.
