respirations
Inhale-exhale sequences counted
Respirations are breaths—the cycles of inhaling and exhaling that sustain life.
The term appears most often in medical contexts, where healthcare workers count respirations per minute as a vital sign: Her respirations were shallow and rapid.
Outside clinical settings, the singular respiration or the verb breathe is more common.
