In particular, due to significant advances in dialysis techniques, patients suffering from end-stage renal disease (ESRD) can survive longer than ever before. Because these patients don't die as quickly as they used to, and as kidney failure increases with the rising age and prevalence of high blood pressure and diabetes in
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
