respiratory therapy overview
The AirWave™ continuously helps you to:
Detect ETT obstructions
Monitor ETT tip movement
- Obstructions are associated with increased work of breathing and prolonged or failed weaning
- Provides real time feedback on procedural effectiveness for clearing obstructions
Differentiate tracheal vs. malpositioned intubation
- ETT tip movement can lead to bronchial intubation, partial extubation, unplanned extubation, esophageal intubation and micro-aspiration / VAP and can increase frequency of chest x-rays
- Provides real time feedback to warn the clinician when the tube tip has migrated into a "danger zone"
Optimize the plan of care:
- Easily identify bronchial and esophageal intubations
- Provides real time feedback with no respiration or circulation required
- More quickly identify the cause of an ETT obstruction and see the effectiveness of your intervention
- Know when the ETT tip has moved, in what direction and by how much
- More readily identify incorrect ETT position
how it works
The AirWave™’s sound waves monitor the airway, alerting clinicians in real time of situations that may lead to unplanned extubations, endotracheal tube obstructions, endobronchial intubation, or esophageal intubation.

Using principles similar to sonar, the SonarMed® AirWave™ sends a sound signal into the endotracheal tube and records the returning echoes that arise from within the tube and patient airways. The timing and amplitude of these echoes are analyzed by the system to non-invasively measure:
- Passageway Size Around Tube Tip: The system analyzes the echo that comes from the tube tip to estimate the size of the passageway relative to tube diameter. This information may help clinicians identify and correct esophageal intubation and endobronchial intubation.
- Degree and Location of Obstructions Within the Tube: The system analyzes the timing and amplitude of echoes that come from within the tube to estimate the location and size of obstructions. This may help clinicians identify an obstruction that forms in the endotracheal tube so it can be removed before the patient is harmed. It may also help the clinician differentiate patient biting or tube kinking from lung secretion buildup by noting the reported location of the obstruction.
- Tube Tip Movement: The system estimates relative movements of the tube by tracking the timing of an echo that comes from within the lungs. This information may help clinicians identify and correct situations that can lead to unplanned extubation or endobronchial intubation.
