Stemoscope PRO Precordial Stethoscope
A wireless precordial stethoscope vs a tubed traditional stethoscope, which one do you prefer?

The Untethered Bluetooth Precordial Stethoscope

A precordial stethoscope, sometimes called pretracheal stethoscope or sedation stethoscope, allows the anesthesiologist, certified registered nurse anesthetists (CRNAs) and dentists to immediately detect changes in the rate and character of heart and breath sounds, and it often gives the first warning of a physiologic alteration (e.g., right main bronchial intubation, wheezing). Traditional precordial stethoscopes have long tubes and it is inconvenient for long time wearing. Thanks to the precordial stethoscope Bluetooth functionality, Stemoscope PRO provides you untethered auscultation freedom.

The Stemoscope PRO's wireless connectivity offers anesthesiologists and CRNAs a remarkable benefit: unrestricted mobility during precordial auscultation. This is particularly crucial for assessing cardiac sounds, as it allows clinicians to position the stethoscope accurately on different auscultation sites without any physical constraints. The Stemoscope PRO is a simple and effective means to assess the quality of heart sounds, rate, and rhythm, as well as breath sounds. A change in the intensity of heart sounds indicates a decrease in blood pressure and possibly cardiac output. The freedom of movement enables a comprehensive evaluation of the auscultatory findings that may be missed using traditional precordial stethoscopes.

Secure The Precordial Stethoscope with Double-Sided Adhesive

The double-sided adhesive ensures that the Stemoscope PRO stays firmly in place on the patient's chest, providing consistent and uninterrupted sound transmission throughout the procedure. The adhesive is gentle on the skin, making it easy to apply and remove.

The double-adhesive feature of the Stemoscope PRO makes it the best precordial stethoscope choice for anesthesiologists seeking reliability, convenience, and superior sound quality in patient monitoring. Experience the difference in your surgical procedures with the Stemoscope PRO. 

Earbuds Recommendation and Consideration

For an optimal experience with the Stemoscope PRO as a precordial stethoscope, we recommend considering the following points when selecting earbuds:

  • Silicone Tips for Bass Sounds: Choose earbuds with silicone tips to enhance the clarity of bass sounds, such as heartbeats. Silicone tips provide a better seal in the ear canal, reducing external noise and improving sound quality.
  • Transparency Mode: Earbuds with transparency mode are highly recommended. This feature allows you to hear environmental sounds along with the auscultation sounds, ensuring you remain aware of your surroundings during patient monitoring.
  • Adjust Amplification or Gain: Find the right balance in volume settings. Too high a volume can lead to loud ambient sounds, while too low may not provide sufficient detail. Adjust the amplification or gain on your earbuds to achieve the best listening experience, ensuring you can hear the sounds clearly without any discomfort.

Using a Bluetooth Speaker with the Precordial Stethoscope

The Stemoscope PRO is designed to pair seamlessly with most Bluetooth speakers. For anesthesiologists and anesthetists, using a Bluetooth speaker can be highly advantageous, as it allows the vital sounds of the patient's heart and lungs to be shared with all medical staff in the room. This capability not only enhances collaborative care but also offers greater freedom of movement during procedures. Here are some key considerations when choosing to use a Bluetooth speaker with your Stemoscope PRO.

  • Bass Performance: While smaller Bluetooth speakers might be convenient, they often struggle to reproduce the deep, resonant bass sounds that are critical for clearly hearing heartbeats. Unlike earbuds with silicone tips, such as the AirPods Pro, which are designed to deliver rich bass directly into the ear, a Bluetooth speaker may require more substantial size and power to achieve similar performance. When selecting a speaker, opting for one with enhanced bass capabilities is crucial to ensure that heartbeats are heard clearly and distinctly.
  • Room Size and Acoustics: The effectiveness of a Bluetooth speaker is also influenced by the size and acoustics of the room. Larger spaces may dilute the sound, requiring a speaker with higher volume and better sound projection capabilities. It's important to choose a speaker that matches the environment in which it will be used to ensure optimal audio clarity.
  • Testing Before Use: While it may be challenging to recommend a specific Bluetooth speaker for use in all precordial stethoscope scenarios, conducting a simple test can be informative. Even if you do not yet own a Stemoscope PRO, you can use our sample recordings to assess the audio quality. Play these recordings through your Bluetooth speaker streamed from a phone to evaluate whether the sound meets your clinical needs.

By considering these factors, you can effectively enhance your use of the Stemoscope PRO in clinical settings, ensuring that all medical personnel can benefit from clear, audible monitoring of vital signs.

    Comparison with Traditional Precordial Stethoscopes

    As a precordial stethoscope, the Stemoscope PRO offers several advantages over other precordial stethoscopes:

    • Wireless Auscultation: The Stemoscope PRO's wireless design eliminates the need for tubes, providing greater mobility and flexibility during patient monitoring.
    • Convenience: Without the constraints of tubing, the Stemoscope PRO allows for easier positioning and adjustment on the patient's chest, enhancing comfort for both the patient and the healthcare provider.
    • Advanced Features: Equipped with Bluetooth connectivity and compatibility with various earbuds, the Stemoscope PRO offers a modern and versatile approach to auscultation.
    • Improved Hygiene: The absence of tubing reduces the risk of contamination and makes the Stemoscope PRO easier to clean and maintain.

    In summary, the Stemoscope PRO provides a more convenient, hygienic, and technologically advanced alternative to traditional precordial stethoscopes, making it an ideal choice for anesthesiologists and anesthetists.


    Reviews from Anesthesiologists and Anesthetists


    IV sedation dentistry

    with new Board rules requiring auscultation for our moderate sedation patients, we needed an easy system to achieve this. With a recommendation from an oral surgeon, we purchased the Stemoscope PROs. They are easy to setup and use. So far, so good.


    Excellent product

    I've been searching for a wireless precordial stethoscope to monitor breathing during open airway anesthesia cases and this works perfectly! Its a quality device that performs exactly as its supposed to. I use the android app with my phone paired with bluetooth headphones and dont have any connection issues. My only one complaint is battery life is not as great as I had hoped. Charged to 100% in the morning, it didnt get through a full day of surgeries. Knowing this, I can easily charge between cases or during lunch.


    Works Great, Love being wireless!!

    As a CRNA that does dental anesthesia I love having the Stemoscope Pro. Before I used a traditional precordial stethoscope with it tethered to my ear piece. I love being untethered, and the sound quality is much better. I use the Stemoscope pro with my Jabra Elite 4 active earbuds and they work fantastic. They quickly connect and the sound quality is fantastic. Love it!!


    Das perfekte Stethoskop der Neuzeit

    For me as a specialist in anesthesiology, the Stemoscope is perfect for auscultating patients well and safely. I can only recommend it to every colleague and am very enthusiastic myself. The function is just as good as with the Littmann Cardiology and I'm curious to see whether the durability is just as good. The Stemoscope Pro is definitely recommended


    Only some slight tweaks would make this product perfect

    I am a pediatric anesthesiologist and use this for airway cases as a precordial stethoscope. Sound quality is wonderful, I really like the additional features the different Bluetooth modes offer , and the durability/portability is excellent. The only thing that would make this product perfect specifically for me would be a way to adhere the stethoscope to a patient's chest - I've seen it with other precordial scopes and I would prefer that to taping it. Very glad I bought it and it's a great product.



    As an anesthesiologist delivering sedation in office settings, it is nice to be untethered. The device works nicely with the AirPods in transparency mode. Haven’t tested battery life over 5 hours, up to that time, it has worked for me.


    Very useful!

    I do anesthesia for oral surgeries and have absolutely loved this! Im using it with Beats ear phones and its SO clear. Earphones definitely matter for clarity. My JBL headphones were not as clear sounding. I love being able to hear breath sounds during surgery on my older and younger patients.


    Excellent product

    I am a pediatric dentist and use this during moderate sedation to monitor the patients airway. The Bluetooth connection is amazing and allows me to move around the operatory uninhibited. I am able to listen through my headphones or if I want more spatial awareness I am able to connect it to a Bluetooth speaker. This allows me to better listen to other sounds while working while also allowing my assistants to listen. Amazing product!


    Great precordial for anesthesia

    Fantastic device. As a practicing CRNA I use it quite often for pediatric cases. I really like listening to breath sound??s during wake up. Adding another monitor keeps the pt that much more safe. Reducing reaction time to airway reactivity.
    I like that the stethoscope has a lung or heart mode, and you can pair them with your phone/air pods or go directly to the AirPods.


    Great addition!

    A colleague had recommended this product as I was looking for a simple, reliable, cordless option to monitor breathing while patients are under anesthesia. I was impressed by the ease of set up, sound quality and range of the product. So much so that I purchased another for my partner.


    Great Precordial Stethoscope use during open airway anesthesia/IV sedation

    I'm an Oral and Maxillofacial surgeon. IV anesthesia / open airway anesthesia is part of my daily routine. In my state, a precordial stethoscope is required during every procedure. I paired the stemoscope with an old smart phone. Every team member in the procedure room can hear the patient breathing and if they can't they intervene. It has made our practice safer. Contact me, and I'll set up a table at our next conference/meeting and show your product off for you. Great alternative to the analog earpiece and the only other electronic precordial stethoscope is corded, does not have an app, and is more expensive.


    Awesome product

    During my anesthesia training we often had precordial stethoscopes on pediatric patients or patients with difficult or otherwise tricky airways. I really like the ability to hear patient lung sounds and the freedom to move away from the patient (at a safe distance obviously, never abandon a pt). A traditional precordial has a wire or tube that keeps you tied to the patient. So these are really nice. Open airway cases become increasingly easy to manage with the stemo. You know immediately if the patient is obstructing. I haven't tried to pair to the stemo directly to airpods, but the app works fine for pairing to your phone. Sound quality is better than a regular stethoscope.
