"a powerful learning tool..."
J.J, Ward, MEd, RRT in Respiratory Care
The concept of R.A.L.E.® Lung Sounds as a computer-aided instruction program on chest auscultation
originated at the Respiratory Acoustics Laboratory (Prof. H. Pasterkamp, MD,
FRCPC), Dept. of Pediatrics and Child Health, University of Manitoba, in
Winnipeg, Canada. Breath sound recordings at the laboratory were used on
occasion when bedside teaching of auscultation was limited by the access to
instructive cases. Positive and encouraging feedback from medical students
was a major incentive to develop a formal teaching program that incorporated
many tools originally designed for research purposes.
Today, R.A.L.E. Lung Sounds
still uses the graphic display of sounds and air flow
("respirosonograms") that help in understanding the relation of auscultation
findings and breathing pattern. Dedicated hardware is no longer required -
the high-fidelity recordings of respiratory sounds are played back through any
Windows-compatible 16-bit audio system. The latest version of
R.A.L.E.® Lung Sounds has links to the Internet for relevant
instruction on lung anatomy and physiology. With up-to-date references and an
extensive collection of quiz cases for the self-assessment of auscultation skills,
R.A.L.E. Lung Sounds
offers a comprehensive resource for anyone who uses a stethoscope.
