Summary

First part of a 2 part study with the same IRB protocol #, and labeled 'A'. Investigators hypothesized that clinical muscle strength assessment (manual muscle testing) predicts the ability to protect the airway during swallowing in long-term ventilated subjects. More specifically, the investigators hypothesized that low muscle strength is associated with the inability to clear secretions from the peri-laryngeal area (valleculae and pyriform sinus residue scale (VPSR scale [NRS: 0-4] of > 1) and entering the materials into airway (PAS scale [1-8]> 1), which should predispose to endotracheal aspiration.

Eligibility Criteria

Inclusion Criteria

  • Patients admitted to the Respiratory Acute Care Unit and Surgical Intensive Care Unit, units with a mixed collection of long term ventilated patients in a major academic teaching hospital.
  • Age over 18 years.
  • Long-term ventilated patients (>10 days) with tracheotomies

Exclusion Criteria

  • Decreased level of consciousness as defined by a Richmond Agitation Sedation Scale (RASS) of 0.
  • Non-cooperative patient, CAM score positive for delirium.
  • For women: pregnancy.
