Connecting one leg of a U tube to a positive pressure source and leaving the other open to atmosphere is a gauge pressure measurement. Thus gauge pressures fluctuate with changes in atmo­ spheric pressure. Adding the atmospheric pressure to

Hypertensive crisis. This stage of high blood pressure requires medical attention. If your blood pressure readings suddenly exceed 180/120 mm Hg, wait five minutes and then test your blood pressure again. If your readings are still unusually high, contact your doctor immediately. You could be experiencing a hypertensive crisis.

The first industrially useful synthesis of polyethylene via the high-pressure polymerization of ethylene gas was developed in 1933–35 and commercialized in 1939. This yielded a low-density polyethylene (LDPE) that was thermally processable and suitable for many applications, for example, tubing.

High blood pressure or hypertension is a condition in which pressure in the blood vessels is higher than it should be. Blood pressure is measured as two readings, systolic and diastolic. Normal blood pressure is 120/80. New guidelines state that blood pressure between 120/80 and 129/80 is elevated, and 130/80 is high.
