Which of the following are signs of respiratory distress?

The signs of respiratory distress primarily relate to the body's struggle to maintain adequate oxygenation and ventilation. An increased respiratory rate indicates that the body is attempting to compensate for a lack of oxygen or an increase in carbon dioxide levels. The use of accessory muscles suggests that the individual is experiencing difficulty breathing, as they engage additional muscles to assist with ventilation. Abnormal lung sounds, such as wheezing, stridor, or crackles, further indicate underlying issues in the airways or lungs, which are critical signs that the body is in respiratory distress.

Recognizing these specific signs allows EMTs and other healthcare professionals to identify patients experiencing respiratory issues quickly and intervene appropriately. This knowledge is crucial in providing timely treatment and improving patient outcomes.
