Laryngeal Tube LTS-D
supraglottic airway device
Reduction of aerosol spread
Atraumatic for patients
The Laryngeal Tube LTS-D is a 2nd generation supraglottic airway (with drain tube) and an alternative adjunct to temporarily secure the airway during emergency situations, e.g. cardiopulmonary resuscitation, in hospital as well as prehospital environments.
Multiple ventilation outlets for efficient ventilation
Drain tube to prevent the risk of aspiration
Thin walled cuffs allow maximum airway leak pressure and reduce the spread of aerosol thanks to efficient pharyngeal sealing. This is achieved at low cuff pressure (<60 cmH20) making the LTS-D atraumatic to the mucosa.
Teeth mark as indicator for correct depth of insertion
The LTS-D is easy to insert and use, even with minimal training. In situations with limited space or in patients with minimal mouth opening the slim design of the laryngeal tube facilitates insertion.
Drain Tube / Teeth Mark
- Drain tube recommended as current standard in international guidelines. All LTS-D sizes include the drain tube as standard.
- Providing the largest suction capability with easy access can accomodate up to 18 Fr gastric tube
- Insertion of a gastric tube is helpful to confirm correct placement of the LTS-D
- The teeth mark is an indicator regarding the correct depth of insertion and for orientation and repositioning purposes
The colour coded system has proven invaluable in emergencies as the syringe indicates the recommended maximum inflation volume.
Sizes Laryngeal Tube LTS-D
The LTS-D is available in 7 sizes. For use from newborn to adult. The size selection depends on weight and body size.
Higher 72-hour survival in adults with OHCA (LTS-D compared to ETI).
Exchange of LTS-D for Tracheal Tube
Possibility of exchanging the LTS-D (in situ with deflated cuffs) for a Tracheal Tube using Video Laryngoscopy and a Bougie.
Reduction of Aerosol Spread
The application of the LTS-D in combination with a breathing system filter leads to a remarkable reduction of aerosol spread during aerosol generating procedures (AGP) e. g. chest compressions.
Uninterrupted Chest Compressions
Easy to insert especially in cases of cardiac arrest without interruption of chest compressions. This leads to significant reduction in no-flow-time. Due to a very high airway leak pressure, uninterrupted chest compressions during CPR are possible.
Application Note for the Laryngeal Tube
VBM would like to stress the importance of cuff pressure measuring as it is described in the VBM instruction manual: Excessive cuff pressure can lead to swelling of the tongue. Adjust the cuff pressure to max. 60 cmH2O via the VBM cuff pressure gauge. Please note our
