AI Article Synopsis
- This study investigates the use of a simple measure (delta SpO2 during a sit-to-stand test) to predict pulmonary function issues in patients with interstitial lung disease (ILD), an area where traditional tests are challenging to conduct in primary care.
- Results showed a strong correlation between delta SpO2 and the diffusing capacity of the lungs for carbon monoxide, meaning delta SpO2 can effectively indicate gas exchange problems.
- The findings suggest that measuring delta SpO2 could be a valuable, accessible tool for identifying lung function impairments in ILD patients.
Article Abstract
Background: Although pulmonary function tests (PFTs) are important in patients with interstitial lung disease (ILD), they cannot be easily performed in a primary healthcare setting. This study aimed to examine the usefulness of the difference between pulse oxygen saturation (SpO2) at rest and the lowest SpO2 during the 1-min sit-to-stand test (delta SpO2-1STST) for predicting pulmonary function impairment.
Methods: We retrospectively reviewed 116 patients with ILD who underwent 1STST and PFTs.
Results: The delta SpO2-1STST and diffusing capacity for carbon monoxide (DLco) strongly correlated (ρ = 0.70). The delta SpO2-1STST was effective in predicting impaired gas exchange (cut-off value, -4%; AUC, 0.86; sensitivity, 74%; specificity, 87%).
Conclusions: The Delta SpO2-1STST may be a reasonable tool for predicting abnormalities in PFTs.
