From the Guidelines
A tracheostomy (trach) mask and a tracheostomy (trach) collar are different devices used for oxygen delivery in patients with tracheostomies, with the mask being a variable performance device that delivers concentrations up to 60-70% oxygen.
Key Differences
- A tracheostomy mask is connected to a humidification system via elephant tubing and is used to deliver supplemental oxygen to patients with tracheostomies, with the goal of maintaining a patent tracheostomy tube and reducing secretions 1.
- A tracheostomy collar, on the other hand, is also used for oxygen delivery, but there is limited information available on its specific use and functionality compared to the tracheostomy mask, although it is mentioned as being widely used 1.
Clinical Considerations
- When using a tracheostomy mask, it is essential to humidify the supplemental oxygen to prevent dryness and discomfort in the patient, as the tracheostomy tube bypasses the natural mechanisms for warming and moisturizing inspired gases 1.
- If a patient requires a higher concentration of oxygen than what a tracheostomy mask can deliver, an alternative delivery system, such as a T-piece device fitted directly to the tracheostomy tube, may be necessary 1.
Device Selection
- The choice between a tracheostomy mask and a tracheostomy collar may depend on the individual patient's needs and the specific clinical setting, with the mask being a more commonly described device in the context of oxygen delivery 1.
From the Research
Tracheostomy Masks and Collars
The provided studies do not directly compare tracheostomy masks and collars. However, we can gather information about tracheostomy tubes and related appliances:
- Tracheostomy tubes are used to administer positive-pressure ventilation, provide a patent airway, protect from aspiration, and provide access to the lower respiratory tract for airway clearance 2.
- Tracheostomy tubes can be cuffed or uncuffed, and some have a spiral wire reinforced flexible design and an adjustable flange design 2.
- There are various types of tracheostomy tubes, including fenestrated tubes, dual-cannula tubes, and tubes designed specifically for use with the percutaneous tracheostomy procedure 2.
Tracheostomy Care and Complications
Some studies discuss tracheostomy care and complications:
- Tracheostomy-related pressure injuries are a common complication, and research efforts have focused on preventing these injuries 3.
- A tracheostomy support system can be effective in reducing pressure at the device-skin interface and minimizing the risk of pressure injuries 3.
- Tracheostomy tubes can be associated with both early and late complications, particularly tracheal stenosis 4.
Tracheostomy Procedures
The studies also provide information about tracheostomy procedures:
- Percutaneous tracheostomy is a conventional procedure in patients undergoing long-term ventilation on ICU 5.
- The percutaneous tracheostomy procedure can be performed via a tracheal tube or a laryngeal mask, with the latter method providing a better overview for the bronchoscoping person and a lower risk for cuff or bronchoscope lesions 5.
- The timing of tracheostomy remains a subject of debate, and a personalized approach is recommended to find the best possible compromise between avoiding unnecessary delays and minimizing the risks of performing a needless invasive procedure 4.
