automated detection

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 computer software 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 automated 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 software 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.
