Preparation, adjustment and fitting
The patient should relax at least five minutes prior to the test.

• Identify the IC4-L region on the patient’s chest and remove hair if needed.
• Attach the CADScor®Patch to the sensor using the assembly tool.
• Add the clinical factors of the patient in the CADScor®System.

Application and recording

• Attach the sensor and its patch to the IC4-L on the patient’s chest.
• Inform the patient about the recording sequence, instruction sounds and how to breathe.
• Start recording. Firstly a pre-recording is conducted, followed by the official recording loops of 4 x 8 seconds.
• Guided instructions on when to breathe are presented on the screen.
• Do not speak during the recording sessions.

Data analysis

• The recorded sounds are automatically filtered and processed in the device.
• The CAD-score result is displayed on the screen as a number between 0 and 99.

10% of the recordings need to be repeated due to inconsistent data analysis. The same patch can be used up to three times if not removed from the patient’s chest.
