What is the recommended tidal volume for adult patients during mechanical ventilation?

The recommended tidal volume for adult patients during mechanical ventilation typically falls within the range of 500 mL to 600 mL. This volume is considered appropriate because it aligns with the average size of adult lungs and the needs for adequate gas exchange.

Using a tidal volume in this range helps ensure that sufficient ventilation is provided without risking barotrauma or volutrauma to the lungs, which can occur when volumes are set too high. It also aids in maintaining proper oxygenation and carbon dioxide removal without over-distending the alveoli.

Tidal volumes lower than this range may result in inadequate ventilation, while volumes that are significantly higher could lead to potential complications, making 500 mL to 600 mL the most balanced and safe choice for adult mechanical ventilation.
