Ventilator Tube Holder for Patients With a Tracheostomy

Patient A was an 85-year-old female with motor neurone disease and a permanent tracheostomy. She was dependent on a respiratory ventilator, but relatively mobile within the critical care unit. However, the ventilator tubing connecting the ambulatory ventilator (usually located behind the patient) to the tracheostomy interfered with the patient's freedom to move and disturbed the tracheostomy as she changed position. A custom-made garment was designed by the Medical Engineering Department of Cardiff and Vale University Health Board (CVUHB) to hold the tubing still and out of the way. This relieved any pressure or pulling on the tracheostomy tube and allowed the patient greater freedom of movement without requiring additional staff to manage/handle the tubing. Patient A used the garment every day for prolonged periods (2-3 hours) and for a duration of 3 months, before she became bedbound and no longer needed it.

The apparent success of this custom-made garment could be repeated in other patients with similar conditions. Furthermore, it may help to reduce the number of staff required when mobilising a patient and lower the handling burden. This project is intended to explore the use of such a garment in a critical care setting. Patients who can be moved out of bed may be moved several times a day, requiring 3 or more staff members each time. If the garment holds the connector tubing securely during these movements then there are several potential benefits:

• Fewer staff may be required to move the patient
• Improved manual handling processes for staff
• Reduction in adverse events associated with mobilisation
• Improved patient comfort during mobilisation Even small movements of the tracheostomy tube can cause discomfort and coughing, whereas larger movements risk tissue damage, airway trauma or dislodging the tracheostomy. In addition, the patient may have more freedom of movement when using the garment out of bed.

However, it is uncertain if or how the current design of the garment will impact on staff and patient activities. There are several potential disadvantages of using the garment:

• It may be awkward to put on and take off, especially for patients with multiple device connections and/or cannulas, limited upper body mobility, and/or cognitive impairment
• It may interfere with the use of a hoist
• As a result, it may increase the time and/or staff members needed to move the patient
• It may increase motion of the tracheostomy tube resulting in greater discomfort and risk of tissue damage or disruption of the ventilation
• It may be uncomfortable or too hot for the patient
• Staff may become dependent on the garment and be less vigilant of the tubing. Essentially, the study will observe staff using the garment to determine where the potential benefits and limitations exist.
