Respiratory Artifacts
The Respiratory Artifact exhibits a beat-to-beat variation in the blood pressure
caused by intra-thoracic pressure. Changes in the intra-thoracic pressure affect
filling of the ventricles during diastole. This in turn affects the stroke volume of
the heart. A large stroke develops a higher systolic pressure than a small stroke.
To perform Respiratory Artifact simulations, do the following:
1. Access these simulations by pressing the 7 RESPIRATORY ARTIFACT
key. The Respiratory Artifact screen appears.
