Features and predictive value of 6-min walk test outcomes in interstitial lung disease: an observation study using wearable monitors.

ABSTRACT:

Objectives

To describe 6-min walk test (6MWT) outcomes, and to investigate their correlations with cardiopulmonary and lung function among patients with interstitial lung disease (ILD) which was not limited to idiopathic pulmonary fibrosis.

Methods

We collected patients' demographic data and obtained minute-by-minute 6MWT outcomes. Modified Borg scale was employed to assess patients' dyspnoea, whereas New York Heart Association (NYHA) classification and pulmonary function test were used to evaluate patients' cardiopulmonary functions.

Results

Heart rate (HR) exhibited a continuous upward trend, while SpO₂ exhibited an overall downward with a slight increase at the fifth minute. The SpO₂ nadir for 70 patients (9.3%) was lower than 80%. Further, th
