- heart rate > 100
- immobilisation at least 3 days or surgyery in previous 4 weeks
- previous PE/DVT
- haemoptysis
- malignancy with treatment within 6 months or palliative

Answer 1

• clinical signs of DVT +3
• PE number 1 diagnosis or equally likely + 3
• heart rate > 100 + 1.5
• immobilisation at least 3 days or surgyery in previous 4 weeks + 1.5
• previous PE/DVT + + 1.5
• haemoptysis + 1
• malignancy with treatment within 6 months or palliative + 1

< 2 low risk < 1.3 % chance of PE, consider D-dimer or PERC
2-6 moderate risk, 16% chance PE consider D-dimer or CTPA
> 6 high risk, 37% chance of PE ue CTPA. D-dimer is not recommended
