Abstract
Background: Existing devices detect main breathing data and none is aimed to monitor biomechanics
of ventilation motions with small wearable device.
Methods: The used device has been designed for noninvasive wearing to detect main motion
parameters of a rib during ventilation in an experimental campaign with 218 subjects.
Experimental activity is carried out by testing in vivo with human volunteers for
an experimental characterization of ventilation motions as related to normal breathing,
maximal breathing and coughing.
Findings: Findings can be summarized from a numerical analysis of experimental results in
terms of statistical values of ventilation motion parameters in rotation and acceleration
as function of age and sex of the tested subjects. The discussed campaign reporting
results on healthy patients was carried out with the aim to build a reference database
of normal conditions against which the status of patients with both thoracic and ventilation
problems can then be judged. Females showed significantly larger lateral-to-lateral
movements during basal breathing and lateral-to-lateral Z-axis movements during maximal breathing and cough. Males demonstrated wider antero-posterior
Y-axis and cranio-caudal X-axis movements during maximal breathing, while antero-posterior
movements prevailed during cough. Older participants demonstrated larger lateral-to-lateral
Z-axis and antero-posterior Y-axis movements during basal breathing. Young participants
showed more significant increments along antero-posterior Y-axis from basal to maximal
breathing and basal to cough, demonstrating a more efficient muscular activity.
Interpretation: The ventilation motion during ventilation act is useful to detect the status of
ventilation and can give indications for diagnostics and medical solutions even in
thoracic surgery.
