Design outcomes
Primary
| Measure | Time frame |
|---|---|
| In laparoscopic surgery patients undergoing general anesthesia with an inserted arterial line, when patients had mean arterial pressure less than 65mmHg and SVV >10%, the Ea dyn at each point will be measured by varying the volume of ventilation from 8 ml/ideal body weight to 6 ml/ideal body weight. The Ea dyn at each point will be measured. Afterwards, 250 ml of Ringer's solution will be administered rapidly, and patients with a 10% or greater increase in mean arterial pressure will be defined as responders. | — |
