Buying Guide for Stethoscopes

1. Ergonomic Design

Since stethoscopes are one of the most frequently used tools in the medical profession, it’s important that they are comfortable to wear.

Ergonomically-designed stethoscopes may have features like:

  • An angled headset so that the ear tips fit comfortably in the ear canal.
  • Soft ear tips that mold to the ear canal.
  • Lightweight tubing material that doesn’t irritate the neck.
  • An easy-to-tune diaphragm that doesn’t require a lot of pressure.

2. Latex-Free

Many people have latex allergies, which makes a latex-free product more appealing.

Whether you have a latex allergy yourself or you simply want to protect your patients with latex allergies, a stethoscope made with latex-free tubing is a good idea.

Tubing that’s free of other irritating materials like phthalates can also be beneficial to your skin and the skin of your patients.

3. Single Tubing

Tubes that rub together can create a rustling sound within the headset that can interfere with properly diagnosing patients.

Single tubing eliminates this rubbing sound, allowing for clearer acoustics and a greater ability to diagnose and treat patients correctly.

4. Non-chill Diaphragm

Patient comfort is always a top priority for medical professionals.

A diaphragm that is too cold can alarm a patient, particularly pediatric patients, and make for a traumatizing experience.

A non-chill diaphragm stays at a comfortable temperature so your patients are never surprised by an ice-cold diaphragm on their skin.

5. Lightweight Design

Many medical professionals wear their stethoscope around their neck at all times.

It’s important that the stethoscope is made from lightweight materials to avoid skin irritation and heaviness around the neck.

Even something as small as a stethoscope can create neck, shoulder, and back problems if it’s too heavy.

6. Lifetime Warranty

A stethoscope is a big investment, so you want to ensure it’s one that will last a long time.

Lifetime warranties are a good thing to have if your stethoscope breaks or loses parts.

Many companies require you to register the product within a certain time frame in order to qualify for the lifetime warranty so be sure to read all the instructions that come with your stethoscope.

7. Acoustic Quality

Acoustic quality is the most important feature of a stethoscope.

You need to be able to hear even the smallest changes in a patient’s status.

Final Thoughts

A reliable stethoscope can make the job of a cardiac nurse easier and allows them to be more efficient when it comes to diagnosing and treating their patients.

All of these stethoscopes have advantages and disadvantages and choosing the right one depends on the specific requirements of your nursing position.
