In this BSL Heart Sounds Lesson, students listen to their own heart sounds by positioning the SS30L Stethoscope* over the aortic semilunar, pulmonic semilunar, tricuspid, and mitral (bicuspid) valves. They will distinguish the volume, pitch and duration of the sound at each point and determine the point where sounds are best heard, which will be used as the recording point for the heart sounds.
Students will also record Lead II ECG and compare the mechanical events (heart sounds) with the electrical events (ECG) of the cardiac cycle.
* BSL 4.0.2 and above includes a headphone output option for monitoring stethoscope sounds through OUT1/OUT1A/40HP via the MP Analog Output or headphone jack.
BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.

The ETVision (ETV) wearable unit resembles an eyeglasses frame that can be worn by itself or over the participant’s prescription eyeglasses. It contains miniature “eye cameras” that view each eye and a “scene camera” that views the scene in front of the participant, and a microphone. An optional visor can be mounted to the front […]
View AllSolving Physical Stress Issues for Surgeons Physical stress in the operating room is common for surgeons, considering how much time they spend in an upright standing position during surgical procedures. With procedures that require standing for several hours and average reported working times of 60-80 hours a week, surgeons seem to be at risk for musculoskeletal […]
