## Questions & Answers

**Q: Can I use the MD One for manual blood pressures in nursing school and clinicals?**
A: Yes. The MD One is designed to transmit Korotkoff sounds clearly for manual blood pressure checks, along with heart, lung and bowel sounds, so it supports you from skills lab through clinicals and beyond.

**Q: Do I need a bell, or is a diaphragm-only stethoscope enough for med school?**
A: Having both helps. The MD One true bell is designed for low-frequency sounds and the true diaphragm for high-frequency sounds, and a fully rotating stem lets you switch between them during a full exam.

**Q: Why is the MD One chestpiece made of stainless steel?**
A: Stainless steel is dense and durable. The MD One chestpiece is crafted from stainless steel chosen for its acoustic properties and polished to a jewelry-grade finish to hold up to daily use in clinic, on rounds and in the ED.

**Q: Will the MD One help me hear heart and lung sounds on a noisy unit?**
A: The MD One uses long, dense, latex-free tubing designed to help block out ambient noise, so heart and lung sounds come through with clarity even when the unit is busy.

**Q: What is the patented Acoustic Pyramid Chamber on the MD One?**
A: It is a patented MDF chamber design that helps prevent the tubing from kinking, so sound keeps traveling freely from the chestpiece to your ears whether the stethoscope is around your neck or in your pocket.
