Unknown
The description mentions an "auto-speed of sound mode" and an "algorithm will calculate the distance to the carina based on the movement of the tip of the tube." While these involve automated processing and calculation, the summary does not provide enough detail to definitively determine if these functions utilize AI or ML techniques, as they could be based on traditional algorithms.
No
The device is described as a monitoring system that uses acoustic reflection technology to assist in verifying ETT placement, detecting ETT movement and obstruction, and listening to breath sounds. Its purpose is to provide information for clinical decision-making, not to directly treat or modify a physiological function.
No
The "Intended Use / Indications for Use" section explicitly states, "The SonarMed AirWave Airway Monitoring System is to be used as an adjunct to normal clinical practice, and is not to be used as a stand-alone diagnostic system." This indicates it assists in monitoring but does not provide a definitive diagnosis on its own.
No
The device description explicitly states that the system is comprised of a Monitor and a Sensor, in addition to software. This indicates the presence of hardware components beyond just software.
Based on the provided information, the SonarMed AirWave Airway Monitoring System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- SonarMed AirWave Function: The SonarMed AirWave system works by using acoustic reflection technology to monitor the position, movement, and obstruction of an endotracheal tube within the patient's airway. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it is used to assist in verifying placement, detecting movement and obstruction of the ETT, and listening to breath sounds. These are all related to the physical management of the airway and the device within it, not the analysis of biological samples.
Therefore, the SonarMed AirWave Airway Monitoring System falls under the category of a medical device used for monitoring and managing an artificial airway, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use

Device Description
The SonarMed AirWave is comprised of a SonarMed Monitor (Monitor) that is used in conjunction with a single-patient use SonarMed Sensor (Sensor) and software that operates the Monitor and Sensor. The Monitor is powered from an external power supply and has a battery backup. When in use, the SonarMed 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.
Using acoustic reflection technology, signals from the Sensor are displayed on the Monitor showing the clinician:
• The baseline location of the ETT tip as established by the clinician
• Quantification of diameter of the anatomical structure around the tip of the ETT
• ETT movement relative to the baseline location
- ETT occlusion / obstruction information including percent obstructed and location of the obstruction
The clinician can choose whether to view information about the patient's airway in either a waveform or graphic on the Monitor's LCD. Additionally the clinician can use the microphones to listen to breath sounds. This information should only be used in an adjunctive manner to assist with management of the artificial airway of the patient.
The monitor allows the user to manually adjust the sound of speed. This is to compensate for the changes in the sound of speed with high oxygen concentrations and the use of anesthesia gases. The monitor also has an auto-speed of sound mode. This mode automatically changes the speed of sound.
The monitor allows the user to manually enter the distance to the carina from the chest x-ray. This is an optional feature that the user can elect from the setting menu. Once selected the algorithm will calculate the distance to the carina based on the movement of the tip of the tube.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench testing and animal testing were completed for non-clinical testing.
Several bench tests were performed comparing movement and passageway accuracy, and obstruction accuracy, of the infant sized sensor to the predicate, adult sized sensor. All testing passed.
A long-term bench study was conducted to document that the subject device performs as intended during prolonged use with heated, humidified, positive pressure ventilation. The conclusion was that the SonarMed AirWave Sensor functions as intended during prolonged use for over 30 days.
A pre-clinical study utilized an animal model (rabbit) to verify acoustics in smaller airways for precise tracking of tube movement and location. The study concluded that the tracking algorithm is accurate in determining ETT tip movement and passageway size.
The conclusions drawn from the non-clinical testing are that the new, infant sized sensors are at least as accurate as the predicate, adult size sensors in detecting movement, obstruction and passageway size.

Discussion and Conclusion of Non-Clinical Testing
The SonarMed 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 site of exposure is the humidified gas pathway of the patient. SonarMed performed testing for cytotoxicity, sensitization and intracutaneous reactivity, which all passed. Also an exhaustive E&L testing was performed. All of the reported extractable and leachable compounds have been determined to be present at levels well below that which would have any health consequences to the intended neonatal population and large safety marqins (very large in many cases) have been determined from the risk characterizations process.
Both bench testing and animal testing was completed for the non-clinical testing for determination of substantial equivalence.
Several bench tests were performed. One test compared movement and passageway accuracy of the infant sized sensor to the predicate, adult sized sensor. Another test compared the obstruction accuracy of the infant sized sensor to the predicate, adult sized sensor. All testing passed.
A long-term bench study was conducted to document that the subject device performs as intended during prolonged use with heated, humidified, positive pressure ventilation. The conclusion of the bench study was that the SonarMed AirWave Sensor functions as intended during prolonged use for over 30 days.
The pre-clinical study was designed to verify the acoustics in the smaller airways would allow for very precise tracking of tube movement and tube location. The study utilized an animal model (rabbit) that was known to be close to the human neonatal airways. During the study, the endotracheal tube was moved up and down in the trachea, into the bronchus and also into the esophagus. These movements were made in small increments and tracked with the SonarMed monitor.
The pre-clinical study concluded that the tracking alqorithm is accurate in determining ETT tip movement and passageway size.
The conclusions drawn from the non-clinical testing are that the new, infant sized sensors are at least as accurate as the predicate, adult size sensors in detecting movement, obstruction and passageway size and that they function as intended during prolonged use.
Clinical data and conclusions were not needed for this device.
Conclusion The SonarMed AirWave was modified to be small enough for the neonatal/pediatric endotracheal tubes. The sensor was designed to be as small as possible with minimal dead space. The new, infant sized sensors are at least as accurate as the predicate, adult size sensors in detecting movement, obstruction and passageway size, and they function as

intended during prolonged use.
The conclusions drawn from the nonclinical testing demonstrate that the device is as safe, as effective, and performs as well as the predicate device.
