Pulse Oximetry Assessment

In patients with neurogenic dysphagia, is pulse oximetry a reliable assessment tool in identifying episodes of aspiration?

Critically Appraised Topic

The practicing Speech Pathology members of the Adult Swallowing EBP group wished to explore the evidence for the use of Pulse Oximetry, as an adjunct to the bedside clinical assessment of the swallow, in identifying episodes of aspiration (including silent aspiration). PDF Format
