Brief summary
In patients who are unable to be safely taken off a mechanical ventilator a tracheostomy is often placed to help protect their airway gradually reduce the mechanical ventilator support. One-way valves can be used within a ventilator circuit to direct air through the upper airway during expiration, allowing speech and communication. Research suggests the use of speaking valves during mechanical ventilation is safe, improves communication, may reduce time to weaning off ventilation and removal of tracheostomy. This project aims to evaluate whether the early use of a speaking valve within the ventilator circuit in suitable patients results in earlier weaning from mechanical ventilation and earlier communication. The primary outcome will be feasibility and safety with the ability to pivot to a primary outcome of duration of mechanical ventilation post tracheostomy utilising the pilot results. Secondary outcomes include mechanical ventilation duration, ease of communication, patient and family, satisfaction and length of stay.
Interventions
Early use of speaking valve in patients who have received tracheostomy in intensive care units (within 72 hours of tracheostomy insertion) 1.Insertion of standard one way speaking valve into ventilator circuit (speaking valve is put into ventilator circuit for the period of the intervention) 2. Initial application will be performed by speech pathologist and physiotherapist and within 72 hours of tracheostomy. Subsequent applications may be done by suitably trained nursing staff 3. Aim will be for 30-60 minutes initially once and then twice daily up to 60 minutes the following day (may be extended longer with time recorded if tolerated well by the patient). The speaking valve is removed from ventilator circuit at the end of each trial. This will continue daily until the patient is weaned from the ventilator (at which point all patients will have access to non ventilator circuit speaking valves as is standard practice) 4. Successful application, time applied/duration will be recorded and any reason for failure Ventilator strategies will be as per the treating clinician
