Tachypnea is defined as a respiratory rate that exceeds what threshold?

Tachypnea is defined as an increased respiratory rate that typically exceeds 20 breaths per minute in adults. This condition often indicates that the body is experiencing some form of stress or may be responding to issues such as fever, anxiety, metabolic acidosis, or respiratory problems. Understanding the distinctions in respiratory rates is crucial for medical professionals, as it can provide important insights into a patient's condition and the urgency of required interventions. The threshold of 20 bpm is widely accepted in clinical settings when assessing respiratory function and should be a focal point when evaluating patients.
