Conditions
Brief summary
This study will identify whether physiological data collected with clinical information can be used to predict the development of aspiration pneumonia. Additionally, we hypothesize that this information can be used to train a machine learning system for predicting a patient’s risk of developing aspiration pneumonia.
Interventions
Risk factors for the development of aspiration pneumonia will be analyzed. Physiological data taken from all participants will include measures of voluntary and induced cough strength, swallowing-respiratory coordination and indices of oral health (breath analysis). In addition to this, collection of key information from participant medical records will be recorded. Participant involvement will entail approximately 40 minutes of time during one data collection session with a follow-up five minut

In addition to this, collection of key information from participant medical records will be recorded. Participant involvement will entail approximately 40 minutes of time during one data collection session with a follow-up five minute telephone call three months later for some participants. We have a prototype device that measures swallowing-respiratory coordination, cough strength and oral health.
