What is an indicator of respiratory distress?

Accessory muscle use is considered a significant indicator of respiratory distress. When an individual is experiencing difficulty breathing or inadequate oxygen supply, the body may recruit additional muscles to assist with respiration. These muscles include the sternocleidomastoid, scalene, and intercostal muscles, which are not typically engaged during normal, effortless breathing. The use of these accessory muscles signifies that the body is struggling to achieve adequate ventilation and oxygenation, which is a hallmark of respiratory distress.

In contrast, regular heart rate, normal breath sounds, and stable temperature suggest a patient is in a stable state and not currently experiencing significant respiratory issues. These parameters would generally not indicate distress; instead, they reflect normal physiological function. Thus, the presence of accessory muscle use is a clear and alarming sign that demands immediate clinical attention in a patient suspected of having respiratory distress.
