Auto-Titration is an advanced technique used in Nitrous Oxide Conscious Sedation Machines that ensures safe and precise delivery of sedation gases. It automatically mixes Nitrous Oxide (N₂O) and Oxygen (O₂) in pre-set concentration ratios to achieve optimal sedation levels for patients. Once the patient's tidal volume is established, the machine intelligently maintains a constant total gas flow, adjusting in real time to ensure consistent and effective sedation. This eliminates the need for manual regulation, reducing risks and improving procedural efficiency.
