Reducing heart muscle wall thickness, either with surgery or catheter-based alcohol ablation. Dissolving a blood clot. Draining or relieving a pericardial tamponade or tension pneumothorax. Adjusting your ventilation if needed. Changing your body position for vena cava compression syndrome. Decompressing high lung pressures with a needle or tube
