Brief Summary

This proposed research aims to evaluate the feasibility of the piezoelectric sensor as an aid to help clinicians screen for the development of pneumonia in an at-risk population.

Conditions

Stroke; End Stage Renal Failure on Dialysis

Outcome Measures

Primary Outcomes (1)

• Detection of pneumonia

  The piezoelectric sensor detects abnormal chest sounds that is suggestive of pneumonia or fluid overload and is confirmed by CXR.

  3 years

Study Arms (1)

Piezoelectric sensor

EXPERIMENTAL

The piezoelectric sensor will be applied to the posterior chest wall of all recruited subjects once daily at one time point (excluding weekends, public holidays and discharge day) up to 2 weeks whilst he/she is warded, until pneumonia or fluid overload is detected and confirmed by CXR or the subject is discharged, whichever is earlier.

Device: Piezoelectric sensor
