Novel Respiratory Monitoring with Ultrasound
WARF: P160338US02

Inventors: Guelay Bilen-Rosas, Humberto Rosas

The Wisconsin Alumni Research Foundation (WARF) is further developing a device that employs ultrasound signaling, paired with machine learning, to provide early alerts to respiratory compromise and/or failure during sedation.
Overview
Despite technological advancements, morbidity and mortality rates remain high in patients under sedation, often due to delayed detection of early respiratory compromise and/or failure.
The Invention
UW–Madison researchers have developed a respiratory monitoring device utilizing doppler ultrasound signals acquired from the patient’s airway and comparing them to baseline parameters, often via a machine learning algorithm. When a threshold change is detected, an alarm is provided to indicate respiratory compromise and/or failure, which can include early airway compromise, airway failure and/or airway obstruction.
Applications
  • Non-invasive Doppler Ultrasound device to monitor airflow changes in a patient's airway during a medical procedure or as a general patient monitoring tool
Key Benefits
  • Prompts timely airway rescue and reduces the morbidity and mortality rates associated with undetected respiratory compromise and/or failure
  • May be performed before, during or following a procedure
  • May indicate the underlying cause of respiratory compromise and/or failure
  • Advantageous for both clinical and outpatient settings and research and teaching applications
  • May one day complement pulse oximetry, which can often be several minutes late in warning about the onset of oxygen deprivation
Stage of Development
A prototype has been developed.
