† Initial/triage heart rate, minimum 80 bpm and maximum 120 bpm.

‡ Lowest initial/triage oxygen saturation, maximum 92.

§ If creatinine in μmol/L (SI), divide by 88.4 to convert to mg/dL.

The EHMRG is not for use in patients who are dialysis-dependent. See Ann Intern Med. 2012;156:767-775 for 7 day mortality estimates based upon the EHMRG score.
