Question

See Box 24-1 in the text (Treatment of "tet" spells).Knee-chest position increases systemic vascular resistance and promotes blood flow from the right ventricle to the pulmonary artery rather than the aorta.Morphine sulfate decreases irritability and may lead to pulmonary artery dilation,which will increase pulmonary blood flow.Oxygen improves oxygenation and decreases pulmonary vascular resistance.Beta blockers (propranolol)may relax RVOT spasms.Systemic vasoconstrictors (phenylephrine)increase systemic vascular resistance to promote pulmonary blood flow.Sodium bicarbonate,administered to treat acidosis,decreases PVR.
