Which condition is characterized by a respiratory rate exceeding 20 breaths per minute due to pain?

Tachypnea is the condition where a person experiences an elevated respiratory rate, specifically exceeding 20 breaths per minute. This can occur as a result of various factors, including pain, anxiety, or physiological states such as fever or lung conditions. The body responds to pain or discomfort by increasing the respiratory rate to improve oxygen delivery and manage the metabolic demands that might arise due to stress or injury.

In the context of pain, the heightened respiratory rate often reflects the body's natural response to help cope with discomfort and maintain adequate oxygenation, particularly if the pain affects the thoracic region or if the individual is in a state of distress. Understanding this concept is crucial for field medical training, as recognizing tachypnea and its underlying causes can guide appropriate interventions.
