Organ harvesting from Falun Gong practitioners in China must be taken from a living donor (kidneys must be transplanted within 24–48 hours; livers within 12 hours, and hearts within 8 hours). Kirk C. Allison, Associate Director of the Program in Human Rights and Medicine at the University of Minnesota, wrote that the "short time frame of an on-demand system [as in China] requires a large pool of donors pre-typed for blood group and HLA matching," which is consistent with reports of Falun Gong prisoners having blood and tissue tested in custody. He wrote that China's short organ wait times could not be assured on a “random death” basis,
Pipe organ pressures are on the order of . Organ builders often measure organ wind using a U-tube manometer containing water, so commonly give its magnitude as the difference in water levels in the two legs of the manometer, rather than in units of pressure. The difference in water level is proportional to the difference in pressure between the wind being measured and the atmosphere. The 0.10 psi above would register as 2.75 inches of water (70 mmAq). An Italian organ from the Renaissance period may be on only , while (in the extreme) solo stops in some large 20th-century organs may
