CHF, congestive heart failure; HTN, hypertension; COPD, chronic obstructive pulmonary disease; CAD, coronary artery disease; SBP, systolic blood pressure; DBP, diastolic blood pressure; ED, emergency department; SpO₂, oxygen saturation. Continuous variables are reported as the mean (standard deviation) and median (interquartile range). ¹ value calculated by the Wilcoxon test. ² value calculated by the chi-square test. ³ value calculated by Fisher’s exact test. value calculated by the T-test.
