MedSys / Pulmonary embolism / All chapters

Every chapter

Eight chapters, about 12,363 words — roughly 55 minutes end to end. Read them in order or go straight to the one you need.

Recognising it

The symptoms, the presentations that get missed, and the leg signs that point to the source.

  1. Recognising a pulmonary embolism

    The presentations that get missed — collapse, breathlessness on its own, a fast pulse and nothing else — the leg signs that point to the source, and when to call 999. 5 min.

In hospital

The tests that should be done, in order and on time, and how treatment is decided.

  1. The hospital checklist: tests that should be done

    Wells score, D-dimer with the age adjustment, CTPA against V/Q, the blood panel, ECG, echo and leg ultrasound — and the four-hour rules that decide whether anticoagulation starts before the scan. 5 min.

  2. How it should be treated

    Risk tiers in the UK and the new US categories, who goes home the same day, which anticoagulant and why, when clot-busting is used, the 2026 catheter trials, and filters. 8 min.

After hospital

The review, the tests that find a cause, and what changes the risk of another one.

  1. After hospital: making sure it does not happen again

    The three-month review, provoked against unprovoked, how long to stay on anticoagulation, what is and is not investigated for cancer, when genetic and antibody tests change anything, and the follow-up that catches chronic lung damage. 7 min.

  2. Every test, and when it is worth doing

    The baseline bloods, the three-month cancer assessment, every thrombophilia and genetic test with what it means and the timing rules, the extended tests for unusual clots, and the tests that are sold but not worth doing. Applies to DVT and PE alike. 10 min.

  3. Lifestyle, travel and the next decade

    What actually changes recurrence risk, what does not, exercise after a PE, flying, surgery, contraception and HRT, and pregnancy planning. 10 min.

For doctors

The two guidelines on one page.

  1. For doctors: the pathway on one page

    NG158 and the 2026 AHA/ACC guideline side by side, doses, contraindications, special populations, PERT triggers and the discharge checklist. 7 min.

Printable

Take it to the ward or the review.

  1. Printable admission and discharge checklist

    Two columns to tick through: what should have happened in hospital, and what should happen in the months after. Includes the sPESI and Hestia criteria. 3 min.
