What is a sign of respiratory distress?

Increased use of accessory muscles for breathing is a key sign of respiratory distress because it indicates that the body is struggling to get enough oxygen. When the primary muscles used for breathing, such as the diaphragm, are not sufficient on their own, the body recruits other muscles, located in the neck and chest, to assist with the effort. This additional muscular engagement is a physiological response to inadequate oxygenation and might be observed in patients facing conditions like asthma, COPD, or other forms of respiratory compromise.

Monitoring for this sign is critical in the field, as it can be indicative of the severity of the respiratory problem. Assessing whether the patient is utilizing accessory muscles can help in determining the appropriate level of intervention, as it suggests that the patient may need more immediate and aggressive medical assistance.
