Study type | Interventional |
The purpose of this study is to test whether or not the use of a low volume ventilator in an anesthesia machine reduces anesthetic costs significantly as compared to other high volume machines. The study will compare the a low-flow anesthesia machine to a traditional anesthesia machine during routine elective general surgery in patients with ASA ratings of 1-2 under general anesthesia receiving standard care.

Primary | Primary Study Variable: Amount of Gas Vaporized Anesthetic Per Minute Anesthesia | The purpose of this study is to test whether or not the use of a low volume ventilator in an anesthesia machine reduces anesthetic costs significantly as compared to other high volume machines. The study will compare the FLOW-i anesthesia machine to a GE anesthesia machine during routine elective general surgery in patients with ASA ratings of 1-2 under general anesthesia receiving standard care. | Intraoperative (minimum of 2 hours of anesthesia) | |
Secondary | Time to Reach Aldrete > 8 | Time it took for patient to be safely discharged from the post-anesthesia care unit (PACU). The Aldrete Score evaluates recovery after anesthesia and patient readiness to be discharged from PACU. The patient is assessed for consciousness, mobility, breathing, circulation, and color. The evaluation occurs immediately after surgery and then every (1) hour before the patient is deemed ready for discharge. |
Up to 24 hours | |
Secondary | Time to Extubation From Weaning | Time it took to remove patient from mechanical ventilation | Intraoperative (minimum of 2 hours of anesthesia) |
