The mean Blood Pressure BP as collected for the APACHE II score is calculated as follows:
Mean BP = ((2x Diastolic) + Systolic)) ÷ 3
- The data collector is responsible to collect from the chart, the worst BP (be it high or low) during the first 24 hours in ICU.
- there is a BP Helper button to help pick the Sys/Dia combination for the worst mean BP
- The APACHE II score is based on the worst calculated mean BP.
- The mean BP is automatically calculated when the CSV data is uploaded to TMSX.
- when selecting the worst BP, you must also take into account the diagnosis. For example, if a patient is in septic shock, you want to select the lowest BP as opposed to the highest BP which is artificially enhanced by inotropes.
- If BP is not available from the chart because of short stay or death, what specific normal value should be used so we can have an idea how often this is not available? Ttenbergen 15:06, 2 November 2010 (CDT)
mean arterial BP
Look carefully when selecting this value. APACHE II score is based on the worst calculated mean BP (either high or low) which ever gives you the highest points as per scoring table, but you must also take in account the diagnosis. For example if a patient is in septic shock, you would want the lowest BP as opposed to the highest BP that is artificially enhanced by inotropes.
