What changed

The United States Patent and Trademark Office (USPTO) has issued patent US12582796B2 to Vapotherm, Inc. This patent covers a computer-implemented method for adaptive control of gas mixtures for patient oxygenation. The method involves receiving SpO2 data, determining PaO2 data using a lookup table derived from an oxyhemoglobin dissociation curve, and transmitting adaptive feedback control data to an external gas blender system.

This patent grant signifies a new intellectual property asset for Vapotherm, Inc. in the area of medical device technology. While not a regulatory rule imposing new obligations, it highlights innovation in patient monitoring and gas delivery systems. Companies operating in the medical device sector, particularly those involved in respiratory care and patient monitoring, should be aware of this granted patent as it may impact their product development and intellectual property strategies.

Abstract

A computer implemented method is disclosed for providing adaptive control of a gas mixture for delivery to a patient via a separate external gas blender system. The computer implemented method includes receiving first SpO2 data from a regional oximeter via a regional oximeter interface; determining first PaO2 data using a first lookup table derived from a first sigmoid shaped oxyhemoglobin dissociation curve; determining a first gas mixture value using the first PaO2 data; and transmitting first adaptive feedback control data including the first gas mixture value to the separate external gas blender system via a gas blender interface.
