What is the abbreviation for tidal volume?

Tidal volume, which refers to the amount of air that is inhaled or exhaled during normal breathing, is abbreviated as "Vt." This abbreviation is commonly used in respiratory therapy and critical care settings to denote the volume of air exchanged in one breath. It is important to use standardized abbreviations in medical and clinical contexts to avoid confusion and ensure clarity in patient management.

In practices involving ventilators, understanding the tidal volume is essential for setting appropriate ventilator parameters to ensure adequate ventilation and oxygenation in patients. "TV" is also a term that refers to tidal volume but is generally less used in formal medical documentation compared to "Vt." "AV" typically stands for alveolar ventilation, and "VT" can be confused with other terms, hence "Vt" is the most appropriate abbreviation specifically referring to tidal volume.
