low-flow anesthesia
Anesthetic technique using reduced fresh gas flows to minimize volatile agent consumption and environmental impact.
Full Definition
Low-flow anesthesia involves using fresh gas flows significantly lower than patient minute ventilation, typically 0.5-1 L/min, requiring precise control of anesthetic agent delivery and careful monitoring of inspired and expired concentrations. This technique reduces environmental pollution, decreases anesthetic costs, and may provide better humidity and temperature preservation. In cardiac anesthesia, low-flow techniques require careful attention to hemodynamic changes and the potential for awareness during critical surgical periods.
Usage
Usage note: Specify flow rates and monitoring techniques when documenting low-flow anesthetic management.
