1. Quiet environment: Choose a quiet environment for auscultation to reduce the interference of external noise and ensure that the body's sound can be clearly heard.
2. Correct wearing: Gently insert the earplug into the ear canal so that the earplug fits the ear canal, but do not insert it too deep to avoid discomfort. Adjust the length of the ear hook or headband to make the stethoscope comfortable and stable to wear.
3. Good contact: When using a chestpiece for auscultation, ensure that the chestpiece is in full contact with the skin and the pressure is moderate, so that the sound can be heard clearly without affecting the sound transmission due to excessive pressure.
4. Avoid friction: Move the chestpiece as smoothly as possible to reduce the noise generated by friction with the skin that interferes with auscultation.
5. Cleaning and disinfection: The chestpiece of the stethoscope should be cleaned and disinfected between contact with different patients to prevent cross infection.
6. Function selection: If it is a dual-function chestpiece (bell type and membrane type), select the appropriate function according to the sound characteristics of the required auscultation.
7. Focused listening: When auscultating, pay attention and carefully distinguish the frequency, rhythm, intensity and other characteristics of the sound.
8. Combined with clinical practice: The auscultation results should be comprehensively judged in combination with the patient's symptoms, signs and other examination results. The diagnosis cannot be made based on auscultation alone.
