Title: Innovations of Thor A Larson in Respiratory Gas Analysis

Introduction

Thor A Larson is an accomplished inventor based in Hugo, MN (US). He has made significant contributions to the field of respiratory gas analysis, particularly through his innovative patent that addresses contamination issues in gas analyzers.

Latest Patents

Thor A Larson holds a patent for a "System for protecting sample line in respiratory gas analyzer." This invention provides a method and apparatus designed to prevent contamination of gas analyzers used in respiratory gas exchange analysis due to a patient's saliva. The method involves determining a resistance value of the inspired respiratory gas flow in a sample line leading to the gas analyzer. This is achieved by calculating the absolute pressure in the line at the gas analyzer. The pressure difference from atmospheric pressure is divided by the sample flow rate to obtain a resistance value. A microprocessor in the equipment compares the calculated resistance of the flow with a previously stored reference threshold resistance. If the calculated resistance exceeds the predetermined threshold, the microprocessor sends a signal to a vacuum pump used to draw the respiratory gases through the gas analyzer. The vacuum pump is immediately shut down when the calculated resistance exceeds the predetermined resistance threshold, ensuring that any saliva in the sample line is not drawn into the gas analyzer. This innovative approach enhances the accuracy and reliability of respiratory gas analysis.
