Haimovich 2020 qCSI (Table 2 bedside points)
Haimovich 2020 qCSI (Table 2 bedside points): RR ≤22 → 0, 23–28 → 1, >28 → 2; SpO2 >92 → 0, 89–92 → 2, ≤88 → 5; O2 ≤2 L/min → 0, 3–4 → 4, 5–6 → 5. Max 12. Lowest SpO2 and nasal-cannula flow as assigned by the caller. Not a COVID-19 diagnosis, triage order, or the 12-variable CSI gradient-boosting model. Derivation excluded >6 L/min. magent does not measure vitals.
