Which tidal volume range is recommended to maintain oxygenation and adequate elimination of carbon dioxide?

The recommended tidal volume range to maintain adequate oxygenation and elimination of carbon dioxide for patients in respiratory distress or those receiving mechanical ventilation is typically between 6 to 8 mL/kg of predicted body weight. This range helps to ensure that there is sufficient air exchange without risking overdistension of the lungs, which can lead to further complications such as barotrauma.

Maintaining a tidal volume in this range supports effective ventilation, allowing for the removal of carbon dioxide while ensuring that oxygenation levels remain appropriate. Using tidal volumes that are either too low or too high can compromise gas exchange, potentially leading to hypoxia or hypercapnia. The 6 to 8 mL/kg range is considered a balance—adequate for gas exchange and minimizing the risk of lung injury.
