Interventions

Squat

Find Squat in Maneuvers. Squatting transiently increases venous return and systemic resistance. A larger LV cavity and higher afterload usually reduce dynamic LVOT obstruction and delay the MVP click; fixed regurgitation can still increase with afterload.

Overview

Open Interventions → Maneuvers. Choose Off, Active. Effect levels and flow targets represent illustrative modeled responses; they are not clinical dose instructions.

Squatting transiently increases venous return and systemic resistance. A larger LV cavity and higher afterload usually reduce dynamic LVOT obstruction and delay the MVP click; fixed regurgitation can still increase with afterload.

The paused reference covers the route (Supervised postural maneuver; maintain ordinary breathing.), 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: Compare BP, output, LVOT gradient, filling pressures and symptoms; murmur change does not establish treatment benefit.

Step by step

  1. Inspect the untreated disease and active treatment count.
  2. Apply the intervention and compare pressures, forward flow, rhythm and congestion.
  3. Pause for its full reference; use Off or Interventions Reset to restart the comparison.
