Trace convention from the demonstrations: black = mean blood pressure; red = heart rate.

Haemodynamic response

Cardiac output and vascular resistance

CO is a qualitative inference; the recordings measure HR and pressure, not stroke volume.

Interpretation

Awaiting an experiment

Prediction score: —
Rx

Choose a drug, predict the response, and administer it to reveal the mechanism.

Quick guide

Run a complete experiment

  1. 1
    Select the intervention

    Choose a drug, dose, administration pattern, and optional antagonist pretreatment.

  2. 2
    Commit to a prediction

    Predict the direction of HR, mean BP, and SVR before seeing the response.

  3. 3
    Observe the trace

    Separate the direct receptor effect from the final response after baroreflex compensation.

  4. 4
    Explain and test

    Review the mechanism, answer the check question, then compare with another condition.

This is a conceptual teaching model. Values are simulated and must not be used for patient care or clinical dosing.
