01Before testing

  • Confirm identity, purpose, symptom distribution, consent and ability to participate.
  • Review anticoagulants/antiplatelets, bleeding history, implanted devices, infection and relevant surgery.

02Individual decisions

  • Do not independently stop anticoagulants. The clinical team must balance bleeding and thrombotic risks.
  • Deep, chest-wall and diaphragm sampling requires appropriate training and risk assessment, with ultrasound when indicated.

03During and after testing

  • Explain steps and adapt necessary sampling to symptoms and tolerance.
  • Provide appropriate aftercare. New respiratory symptoms after chest-wall sampling require immediate assessment.

Pause and explain

Explain in your own words: “Use enough testing to answer the question without purposeless stimulation or sampling.” Then think of a situation in which it could be misinterpreted.
