POMPE-C Tool for Pulmonary Embolism Mortality calculator
Enter the published formula inputs below to calculate and interpret this score.
Clinical inputs
Allowed range: 50–500 lb
The equation uses pounds. Enter kilograms only through the alternate unit.
Allowed range: 4–80 /min
Use the highest respiratory rate during the previous six hours.
Allowed range: 50–100 %
Use the most recent room-air percent.
Allowed range: 20–250 /min
A rate over 99 beats per minute in the previous six hours receives coefficient 1.027. A rate of 99 does not.

Kline JA et al. Derivation and validation of a multivariate model to predict mortality from pulmonary embolism with cancer: The POMPE-C tool. Thromb Res. DOI: 10.1016/j.thromres.2012.03.015. PMID: 22475313. The NIH manuscript prints P = 100 × (1 − 1 / (1 + exp(3.718 + DNR×1.551 + respiratory distress×0.800 + unilateral limb swelling×0.734 + altered mental status×1.473 + heart rate + respiratory rate×0.044 + SaO2×−0.063 + body weight in pounds×−0.012))). The heart-rate term is dichotomous. Table 2 prints odds ratio 2.8 for heart rate over 99 beats/min, and the adjacent coefficient column prints 1.027, with exp(1.027) equal to 2.79. This implementation multiplies the heart-rate indicator by 1.027. Heart rate over 99 in the previous six hours is positive. Respiratory rate is the highest value in the previous six hours. SaO2 is the most recent room-air percent. In the validation sample, an estimate of 5% or lower had 0 deaths among 50 patients, and an estimate over 50% had 10 deaths among 13 patients. (2012)
