This hand-held simulator generates both heart and breath sounds and is an excellent instructional tool for one to 15 students. Utilizing plug-in menus, instructors can select the appropriate scenario for the classroom situation. The unit includes two sounders allowing students to auscultate with a stethoscope to hear the sounds. Linking the sounders, up to 15 students can auscultate at the same time or a speaker may also be connected (Speaker not included). The tutor is ideal for any setting where the determination of both heart and breath sounds is important. All data used is actual patient sounds provided by plug-in menus. Additionally, the unit has two lights that illuminate during systole (heart menu) and expiration (breath menu). Virtually maintenance-free, the unit is powered by a 9V battery.
