Summary
Subglottic suction tracheotomy tubes significantly reduce saliva aspiration compared to conventional cuffed tubes. This innovation offers a safer airway management option for patients at risk of aspiration.
Area of Science:
- Medical Devices
- Respiratory Care
- Surgical Innovation
Background:
- Conventional cuffed tracheotomy tubes do not prevent aspiration of secretions.
- Aspiration of saliva poses a significant risk in patients with tracheostomies.
Purpose of the Study:
- To evaluate the efficacy of subglottic suction port tracheotomy tubes in reducing aspiration.
- To compare the aspiration-reducing capabilities of Portex Blue Line Ultra Suctionaid (BLUS) tubes with Shiley Disposable Cuffed Tracheotomy (DCT) tubes.
Main Methods:
- A prospective study using a simulated tracheal model.
- Comparison of Shiley DCT and Portex BLUS tracheotomy tubes (various sizes).
- Testing under no suction, intermittent suction, and constant suction conditions with human saliva.
Main Results:
- Continuous suction with BLUS tubes significantly reduced aspirate volume compared to Shiley DCT tubes across all sizes.
- Intermittent suction also showed a significant decrease in aspirate with BLUS tubes, particularly in larger sizes.
- BLUS tubes with continuous suction demonstrated the lowest aspirate volumes.
Conclusions:
- Subglottic suction tracheotomy tubes are effective in reducing the risk of aspiration beyond the cuff.
- The use of subglottic suction ports represents a significant advancement in tracheostomy safety.

01:23Tracheostomy Suctioning II: Procedure
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...
01:26Tracheostomy Suctioning I: Pre-Procedural Steps
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.

01:28Tracheostomy: Procedure and Tubes
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

01:15Endotracheal Intubation I: Procedure
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...
