تعليمات التشغيل

The 3M Littmann Cardiology IV Stethoscope is designed for precise auscultation. Follow these guidelines for optimal performance:

1. Selecting the Diaphragm:

   The chestpiece is double-sided, featuring a large side for adult patients and a smaller side for pediatric or thin patients, or for navigating around bandages. To activate a side, hold the stem and rotate the chestpiece until you feel a click. The active side will be open to the acoustic pathway.

2. Tunable Diaphragm Technology:

   The tunable diaphragm allows you to hear both low and high-frequency sounds without turning over the chestpiece.

   • Low-Frequency Sounds: Apply light pressure to the chestpiece. This allows the diaphragm to flex, enabling the detection of low-frequency sounds like heart murmurs.
   • High-Frequency Sounds: Apply firm pressure to the chestpiece. This restricts the diaphragm's movement, allowing you to hear higher-frequency sounds such as lung sounds.

3. Auscultation Techniques:

   Position the chestpiece firmly on the patient's skin, ensuring no clothing interferes with sound transmission. Listen for heart, lung, and bowel sounds as required by your clinical assessment.
