Validation of Respiratory Rate Measurement Accuracy Using a Smartwatch

Validation of Respiratory Rate Measurement Accuracy Using a Smartwatch

This prospective study evaluates the accuracy of commercial wearable devices by comparing their respiratory rate measurements against clinical standards like spirometers and ECGs in healthy adults. The goal is to determine if these devices are reliable enough for non-invasive respiratory monitoring in both everyday and medical environments.

This prospective interventional study evaluates the accuracy of respiratory rate measurement using commercially available wearable devices. Respiratory rate measured by wearable devices will be compared with reference measurements obtained from a spirometer and ECG.

Healthy adult volunteers will participate in a short experimental protocol including different breathing conditions. Respiratory rate will be recorded simultaneously by wearable devices and reference monitoring systems.

The aim of the study is to determine whether wearable devices can reliably measure respiratory rate and to assess their potential for non-invasive respiratory monitoring in everyday and clinical settings.

Inclusion Criteria:

• Healthy adults aged 18 years or older
• Ability to understand the study procedures and provide informed consent
• Willingness to participate in the experimental measurement protocol

Exclusion Criteria:

• Known respiratory diseases (e.g., asthma, chronic obstructive pulmonary disease)
• Known cardiovascular diseases or conditions limiting safe participation
• Acute illness or infection at the time of measurement
• Neurological or musculoskeletal conditions affecting breathing or the ability to participate in the measurement protocol
• Pregnancy
• Use of alcohol or other substances affecting physiological measurements at the time of the experiment
