How To Use Course Lessons
Each lesson within a course consists of text description the heart or lung sound. A torso illustration indicates the stethoscope chestpiece location. Audio recording of the sound is provided. Phonocardiograms or lung sound waveforms are included with each lesson. These waveforms can be a highly useful aid in learning to recognize heart murmurs. In addition, short videos illustrate the heart's motion, which indicates the origin of each murmur. Blood flow is also animated. For lung sounds, the source (location) of the sound can be revealed.
After completing a lesson, use the blue arrows to view the next lesson. Lessons can
also be accessed by links within the table of contents. When all lessons have been completed, we recommend using the Practice Drill. These practice drills are also required to earn a module certificate of achievement.
