Lesson 1Integrating clinical context: risk factors, timing, pleuritic pain, oxygenation, biomarkers (D-dimer, troponin) and how they change diagnostic weightingThis part dey explain how to mix imaging with patient history for acute dyspnea, putting in risk factors, when symptoms start, pleuritic pain, oxygen levels, and blood tests like D-dimer and troponin to fine-tune diagnosis chances.
