USPTO Patent Application: System to Monitor Respiration During Sedation
Summary
The USPTO has published a patent application for a system designed to monitor patient respiration during sedation using nasal pressure and oxygen flow. The application details a method for identifying breathing patterns and delivering controlled oxygen pulses to ensure patient safety.
What changed
This document is a USPTO patent application (US20260083926A1) for a system and method to monitor a sedated patient's respiration. The proposed system identifies end expiratory pauses, delivers precise pulses of high-flow oxygen (approx. 30 L/min for <0.5 seconds), and synthesizes a respiratory signal based on nasal pressure and oxygen flow measurements. The goal is to determine the patient's breathing pattern, rate, and frequency.
As this is a patent application, it does not impose immediate regulatory requirements or compliance deadlines on healthcare providers or medical device manufacturers. However, it signals potential future technological advancements in patient monitoring during sedation. Companies involved in developing medical devices for respiratory monitoring or sedation management should be aware of this patented technology.

Abstract
This disclosure relates to systems and methods for monitoring sedated patients that are receiving supplemental oxygen flows. A method of monitoring a patient's breathing while sedated includes identifying an end expiratory pause in the patient's breathing pattern and obtaining a first respiratory signal corresponding to a nasal pressure of a patient. The method may also include delivering a pulse of high-flow oxygen during the end expiratory pause at a rate of about 30 liters-per-minute (L/min) and delivering the pulse of high-flow oxygen during the end expiratory pause for less than 0.5 seconds. The method may further include measuring a peak nasal pressure and a peak oxygen flow and synthesizing a second respiratory signal. The second respiratory signal may correspond to the peak nasal pressure and the peak oxygen flow, and may be normalized for the patient. The method may additionally include determining the patient's breathing pattern, rate, or frequency.
