Title: Innovations by Charles H Logan in Respiration Monitoring

Introduction

Charles H Logan is an accomplished inventor based in Portland, Oregon. He has made significant contributions to the field of medical technology, particularly in respiration monitoring. His innovative approach has led to the development of a unique method and apparatus that enhances the accuracy of respiration measurements.

Latest Patents

Logan holds a patent for a respiration monitoring method and apparatus that includes cardio-vascular considerations. This invention focuses on measuring the variations in thorax impedance of a patient due to respiration. The monitor is designed to suppress unwanted signals caused by the patient's cardio-vascular activity. It utilizes circuitry that receives trigger signals immediately following the QRS complex of the patient's ECG waveform. If a specific negative-going slope is detected in the thorax impedance waveform after the QRS complex, it is identified as a cardio-vascular artifact rather than respiration activity. After a predetermined number of these artifacts are detected, the respiration monitor is disabled to prevent cardio-vascular activity from resetting an apnea counter.

Career Highlights

Logan's career is marked by his dedication to improving patient monitoring technologies. His work at Squibb Vitatek Inc. has allowed him to focus on developing innovative solutions that address critical challenges in medical monitoring. His patent reflects his commitment to enhancing the reliability of respiration monitoring systems.

Conclusion

Charles H Logan's contributions to respiration monitoring technology demonstrate his innovative spirit and dedication to improving healthcare. His patented method showcases the importance of integrating cardio-vascular considerations into medical devices, ultimately benefiting patient care.
