Overview
Open Interventions → Maneuvers. Choose Off, Active. Effect levels and flow targets represent illustrative modeled responses; they are not clinical dose instructions.
Transient redistribution of venous blood toward the thorax tests preload responsiveness without an infused fluid bolus. CO increases only with adequate cardiac reserve; congestion may rise with little output benefit.
The paused reference covers the route (Reposition from semi-recumbent to supine with legs elevated about 45 degrees, then restore the starting position.), example doses/settings, indications, adverse effects, contraindications/precautions and monitoring. These details are available after the intervention is selected.
What to monitor in the reference: Measure change in stroke volume/CO rather than BP alone and confirm reversibility. The selected phenotype is illustrative: RAP or wedge alone cannot predict clinical responsiveness.
