What term describes a slow respiratory rate, which is an ominous sign in a child indicating potential respiratory arrest?

The term that describes a slow respiratory rate is bradypnea. In children, bradypnea can be particularly concerning as it may indicate an imminent respiratory failure or arrest. This condition occurs when the respiratory rate drops below the normal range, which can result from various factors such as drug overdose, neurological impairment, or severe respiratory distress.

Recognizing bradypnea is crucial because it signals a potential progression toward more severe respiratory complications. In pediatric patients, the clinical significance of a slow respiratory rate cannot be overstated as it may lead caregivers and healthcare providers to intervene more urgently to ensure the child's airway remains patent and effective oxygenation is maintained.

Understanding the physiological impacts of bradypnea can help in recognizing when a child may need escalation of care, such as supplemental oxygen or advanced airway interventions.
