In the case study above, the patient's SVRI is 2311 dynes/s/cm5/m2. Discuss SVRI: how it is derived and what high or low values indicate clinically
What will be an ideal response?
Suggested response: Discussion should include the following key points: • Systemic vascular resistance index (SVRI) is the resistance the left heart pumps against indexed to body surface area. It is calculated by use of the following formula: SVRI = [(MAP − RAP) × 79.9]/CI, although this calculation is automated with use of pulmonary artery monitoring systems. • High values indicate increased systemic vascular resistance and low values indicate vasodilation. • In this case study the patient initially had low SVRI values (indicating vasodilation), which later increased with the use of a noradrenaline infusion and careful fluid administration.
