摘要

Over the last two decades, the advances in ventilator modalities and technology have revolutionized the mechanical ventilation process. The new anesthesia ventilators constitute adaptations of machines previously used in intensive care units. In this line, the FLOW-i anesthesia ventilator has been recently developed based on the SERVO-i intensive care ventilator platform. However, the FLOW-i behavior has not been so far tested in a leaking circuit. In this study we tested FLOW-i, and compared to SERVO-i, in volume-, pressure-, and pressure-regulated volume-controlled modes (VC, PC, and PRVC, respectively) with gas flows of 6, 1, and 0.3 L/min, booth in airtight and leaking circuit. In the airtight system both ventilators behaved similarly. FLOW-i delivered preset tidal volume and maintained ventilation and circuit pressure at the same levels independently of ventilatory mode or fresh gas flow rate. In the face of a leaking circuit and in PC mode FLOW-i and SERVO-i delivered to the lung model higher tidal volumes (about 90% and 85% of set values, respectively) than in VC and PRVC modes. Additionally, delivered tidal volume did not differ from 6 to 0.3 L/min of fresh gas flow.
