neural network

A combination of a stethoscope that fits in your pocket and an algorithm that runs in the cloud.

ChestPal Pro software uses digital signal processing to convert lung sound recordings into spectrograms. It then allocates the spectrograms into normal, wheeze, crackles, artifact, or heartbeat classes using machine learning algorithms built upon a dataset labelled by respiratory specialists.

The device automatically detects crackles and wheezes that may be hard to hear. The audible and visual results serve as an aid to healthcare professionals in patient management and diagnosis.

Working on your terms

Choose between Spot and Complete exams:

Spot lung exam is best for capturing lung sounds from a select lung areas. It may be convinient for a routine check-up
Complete lung exam is best for capturing lung sounds from all lung fields. It may be useful for an in-depth assessment of a patient presenting with respiratory symptoms

Instant answers

The neural network (NN) analysis of the lung sounds will be presented straight after the recording is completed:

ChestPal Pro differentiates between normal breathing, wheezes, crackles, artifacts, and heartbeat.
The NN uses spectrograms – a visual representation of sounds – to conduct the analysis.
The spectrogram created is available in the app and may help healthcare professionals see subtle sounds that are hard to hear.

Delivered by all healthcare personnel, whatever the setting.

Help bridge care gaps where access to specialists is restricted. Use ChestPal Pro to reliably detect crackles and wheezes which could aid identification of lower respiratory tract conditions. Escalate patients’ care with confidence.

Product Details

Descriptions

The app's main functionality is:

Lung sound recording and classification;
Storing individual patient’s lung exam data;
Sharing lung exam data.

The NN algorithm differentiates between 5 types of sounds: normal breathing, wheeze, crackles, artifacts, and heartbeat. It uses spectrograms – a visual representation of sounds – to conduct the analysis.

ChestPal Pro is intended to be used in healthcare settings on adults, adolescents, and/or children over 3 years old.

Technical information

To use ChestPal Pro, users should connect their ChestPal Pro electronic stethoscope with an Internet-enabled smartphone using the ChestPal Pro app. The app can be used with iOS 12 and newer models, Android 6.0 and more recent models. The smartphone should support Bluetooth 5.
