This device analyses venous pressure to estimate anesthetic depth
• Peripheral venous pressure waveforms can be measured routinely and used to estimate depth of anesthesia
• Applicable to both inhaled and intravenous anesthesia
• Improved patient safety
• Reduces overuse of anesthesia for cost savings for provider
Costs related to surgery can be 40% or more of a hospitals expenses, and anesthesia costs account for approximately 6% of these expenses. The general anesthesia drug market is expected to approach $5 billion annually by 2022. Thus, usage of only the necessary amount of anesthesia can lead to significant cost savings. Additionally, accurate monitoring of anesthetic depth provides for a safer patient experience.
Peripheral venous pressure (PVP) waveforms can be collected from patients using a peripheral intravenous catheter connected to a pressure transducer. An algorithm has been developed by using machine learning to assess the PVP waveform as an estimate of anesthetic depth.
The algorithm has been generated and utilized to assess depth of isoflurane anesthesia in pediatric patients undergoing elective surgery
