摘要

Minute ventilation (V_E) is difficult to measure in the field, but is of considerable interest as it allows researchers to estimate potential inhaled dose of air pollutants. Advances in commercially available wearable technology make it easier to measure V_E in mobile field studies, but the reliability of these systems is unknown. The Hexoskin Biometric Shirt continuously records heart rate through an ECG. Respiratory rate (RR), tidal volume (V_T), and V_E are recorded through a dual band respiratory inductance plethysmography (RIP). Additionally, the shirt contains a 3-axis accelerometer. The presence of the 3-axis accelerometer and the ECG enables three different proxy methods for estimating V_E. To validate the Hexoskin shirt, HR, RR, V_T, and V_E measurements were compared to a 'gold standard' Vmax system in a physiology laboratory at Columbia University Medical Center. Participants carried out an incremental exercise test on a stationary bicycle to validate the shirt at rest, submaximal exercise (SM), and maximal exercise (M). Bland Altman analysis suggested good significant agreement for RR and HR measurements at all levels when excluding improper recordings, and resulted in strong correlations (R= 0.84 to 0.99). Correlation of Ve measurements at maximal exercise was high (R=0.85), but lower at rest (R= 0.49). V_T and V_E measurements taken by the Hexoskin shirt at SM and M exercise had a discrepancy of less than 12%. The Hexoskin shirt is advantageous as it provides three distinct metrics for V_E. In addition to the direct measurements, V_E can be estimated by HR or actigraphy recordings when the dual band RIP sensor does not provide a reliable measure.
