NCT04685902
Approximately 24% of ICU patients require the use of a tracheostomy, which impacts vocalization. A one-way speaking valve (SV) can be used to restore vocalization for this patient population. However, if a patient has an obstructed upper airway, SV placement has potential to pose a risk as it might cause asphyxia or even cardiac arrest within minutes, due to the sudden increased intra-thoracic pressure and decreased venous return. Therefore, upper airway patency is crucial in the patient's tolerability and safety to use SV. However, little is available to assess patient's upper airway patency before SV placement. Currently, the predominate way to evaluate readiness is the clinician's subjective assessment based on the quality of vocalization, perceived comfort, and tolerance following SV placement. In the previous in vitro study, the upper airway patency was strongly correlated with the trans-tracheal pressure and the inspiratory flow from upper airway during SV trial. Thus this clinical prospective observational study is aimed to validate the two methods with upper airway patency, which will be validated by bedside ultrasound examination as well.
