Which of the following is NOT a pertinent characteristic of breathing to assess?

Assessing a patient's breathing involves evaluating various specific characteristics that provide critical information about their respiratory status. The key characteristics typically considered are the rate, rhythm, and quality of breathing.

The rate refers to how many breaths a person takes in a minute, while rhythm indicates the pattern of the breathing—whether it is regular or irregular. Quality encompasses the effort of breathing, such as whether it is labored or easy, and may include observations regarding the sounds made during respiration.

In contrast, the emotional state, while it may have an indirect effect on breathing patterns (such as anxiety causing faster breaths), is not a direct characteristic of breathing itself. Thus, it does not provide specific data that can accurately assess a patient's respiratory function when evaluating their condition. For effective assessment, focusing on direct respiratory indicators—rate, rhythm, and quality—provides clearer insights into a patient's current respiratory health.
