What is ChestPal Pro?

ChestPal Pro is an FDA listed prescription device intended to monitor and record lung sounds and automatically detect crackles and wheeze. It consists of a Bluetooth-enabled stethoscope and an AI-powered app.

What is its intended use?

ChestPal Pro is a prescription device intended to monitor and record lung sounds and automatically detect crackles and wheeze. When interpreted by healthcare providers, ChestPal Pro aids in diagnosis and patient management.

Who is ChestPal Pro designed for?

It was designed for use by any healthcare provider who performs lung auscultation, including doctors, nurses, EMTs/first-responders, and students.

How does its AI analysis work?

The app provides an automatic computer analysis of lung sound recordings using an AI algorithm. It differentiates between 5 types of sounds: normal breathing, wheeze, crackles, artefacts and heartbeat. .

The algorithm uses spectrograms – a visual representation of sounds, to do such analysis. Normal breathing, wheezes, crackles, and heartbeat analysis are provided when the spectrogram created by the user receives the highest match with a respective class of spectrograms derived from recordings labelled by respiratory specialists.

Artefacts analysis is provided when the spectrogram created by the user receives the highest match with a class of spectrograms derived from recordings of skin or hair rubbing against the stethoscope membrane, fingers moving on the stethoscope during the recording, stethoscope repositioning during the recording, electromagnetic interference, background noise, etc.

Is there a pre-defined recording duration?

Yes, each recording lasts 5 seconds. During the development process it was determined this is sufficient time for the trained AI algorithm to analyze lung sound recordings. It also allows caregivers and providers to record sound from all lung areas without putting too much strain on a patient.

See " How does its AI analysis work?” page” and “Choosing the appropriate lung exam type” link to “Choosing the appropriate lung exam type” page” for further information on how ChestPal Pro can assist you in recording and registering your patients’ lung sounds..
