Quick Recognition of Aortic Dissection

Identification of Aortic Dissection Based on Pulse Oxygen and Ultrasound Doppler Waveforms

This is an observational study that establishes a cohort of patients with high risk chest pain who have been identified by CTA for aortic dissection. We then used this cohort to validate the accuracy of identifying aortic dissection based on extremity oximetry and Doppler waveforms.

Inclusion Criteria:

• High risk chest pain with CTA

Exclusion Criteria:

• shock
• coma
• severe peripheral vascular diseases
