There were no differences between the studied groups in respect to the following potential triggers of hyperventilation: anaemia (e.g., haemoglobin 13.36 ± 2 vs 13.25 ± 2 mg/dL, p = 0.72), hypoxemia (sO2 92.5 ± 5.2 vs 92 ± 5.6%, p = 0.57), infection status (e.g., CRP 10.5 [4.9–26.4] vs 7.15 [3.45–17.35] mg/L, p = 0.47; IL-6 9.7 [0.5–20.9] vs 8.3 [1.0–21.4] pg/mL, p = 0.93;. Here, IL6 is linked to infection.
