Latest Patents

On-line Fault Detection and Correction in Anesthesia Delivery System. This invention compares three sets of measurements: the clinician’s settings and the system’s delivered gas concentrations, readings from a feedback respiratory analyzer, and readings from a monitor analyzer in the patient circuit. A CPU evaluates the measurements under high-flow conditions, when they should be consistent. Based on the comparison, the system can identify potentially faulty devices, adjust for analyzer bias, and take other safety or corrective actions.

Automatic Bellows Refill. This invention detects a large leak in an anesthesia system’s patient breathing circuit and reduces fresh-gas flow to limit gas loss. Once the leak is alleviated, the system increases flow to refill the circuit, then returns flow to the clinician’s desired maintenance level. The refill uses the same gas and anesthetic-agent composition selected by the clinician.

Career Highlights

Keitel’s listed patents address practical challenges in anesthesia delivery, including detecting equipment faults, responding to leaks, and restoring a patient breathing circuit efficiently. These designs emphasize automated monitoring and adjustments intended to support reliable system operation.

Collaborations

Keitel’s listed coworkers include Robert Q. Tham and Duncan P. Bathe. His work is associated with Ohmeda Inc.

Conclusion

Todd Keitel’s patented work focuses on improving anesthesia-system safety and reliability through automated fault detection, corrective functions, and patient-circuit refill control.
