Outcome Measures

Primary Outcomes (1)

  • Presence or Absence of Aspiration

    Presence or absence of matter passing between or below the vocal cords during swallowing, particularly in the absence of cough reflex stimulation - novel intervention to acoustically detect silent aspiration in patients

    1 hour

Interventions

Acoustic analysis plus pulse oximetry
