SonarMed Inc. Recalls Airway Monitors Due to a Software Anomaly Resulting in Failure to Detect a Partial Obstruction in 2.5mm Sensors and Up To 3mm Distal to the Sensor Tip

The FDA has identified this as a Class I recall, the most serious type of recall. Use of these devices may cause serious injuries or death. 

Recalled Product 

  • Product Names: SonarMed Airway monitors 
  • Product Codes: OQU 
  • Model Numbers: AW-M0001
  • Distribution Dates: October 13, 2022 to October 6, 2023
  • Devices Recalled in the U.S.: 145
  • Date Initiated by Firm: March 25, 2024

Device Use 

The SonarMed airway monitoring system (AMS) is comprised of a SonarMed monitor (monitor) that is used in conjunction with a single-patient use SonarMed Sensor (Sensor), connected via an external cable connection, and software that operates the Monitor and Sensor.

Diagram of the AirWave Monitor and AirWave Sensor

When in use, the SonarMed AirWave airway sensor is placed in-line between the ventilator circuit and the proximal end of the endotracheal tube (ETT) of a patient who is connected to a ventilator. The Sensor replaces the standard 15-mm connector (also known as the “hub”) that comes with the ETT and utilizes acoustic reflection technology to provide real-time information to clinicians. This includes the baseline location of the ETT tip, estimation of passageway size around the tip, detection of ETT movement, and identification of occlusions or obstructions.

The SonarMed airway monitoring system is intended for use by trained medical professionals to support the management of artificial airways in hospital settings such as intensive care units, operating rooms, emergency departments, and during intrahospital transport. It is meant to complement standard clinical practices and is not intended as a standalone diagnostic tool. The system is suitable for use across a wide range of patients, including neonates, infants, children, adolescents, and adults, covering a size range from 2.5mm to 9.0mm for endotracheal tubes.

Reason for Recall   

SonarMed Inc. is recalling the SonarMed Airway monitoring system because of a software issue resulting in failure to detect a partial obstruction within 2.5mm sensors and extending up to 3mm distal to the sensor tip. 

The use of the affected syringe may cause serious adverse health consequences, including delays in treatment, accidental insertion into the bronchial tube, lower oxygen levels (hypoxia), air leaking into the chest cavity (pneumothorax), not enough air reaching the lungs (hypoventilation), harm to the tissues, slow heart rate (bradycardia), or even breathing problems leading to respiratory failure.

There have been no reported injuries or death.

Who May be Affected  

  • Health care providers who use the SonarMed airway monitoring system to support the management of artificial airways.
  • People who receive care with the SonarMed airway monitoring system is intended for use by trained medical professionals to support the management of artificial airways.

What to Do  

On March 25, 2024, Medtronic, on behalf of SonarMed Inc. sent all affected customers an Urgent Medical Device Recall notice. 

The letter requested customers to: 

  • Discontinue use of affected monitors and quarantine all SonarMed Airway System products.
  • Return all quarantined SonarMed airway monitors to Medtronic.
  • Complete and return the included Customer Confirmation Form to rs.gmbmitgfca@medtronic.com
  • Share this information anywhere the SonarMed Airway monitors may have been transferred or distributed. 

Contact Information

Customers in the U.S. with questions about this recall should contact Medtronic Representative or Customer Service at 800-962-9888, Option 2.
