Abstract Introduction Pulmonary embolism PE is one of the greatest diagnostic challenges in prehospital emergency setting. Most patients with suspected PE have a positive D-dimer and undergo diagnostic testing. Excluding PE with additional non-invasive tests would reduce the need for further imaging tests. We aimed to determine the effectiveness of combination of clinical probability and end-tidal carbon dioxide PetCO2 for evaluation of suspected PE with abnormal concentrations of D-dimer in prehospital emergency setting. Methods We assessed clinical probability of PE and PetCO2 measurement in 100 consecutive patients with suspected PE and positive D-dimer in the field. PetCO2 28 mmHg was considered as the best cut-off point. PE was excluded or confirmed by hospital physicians
