The heart, brain, kidneys, hormones and nervous system work together to regulate blood pressure. If the blood pressure is too low or high, heart or kidney failure can result. Normal resting blood pressure for adults is systolic (top number) less than 120 mmHg and diastolic (bottom number) l...
Any negative pressure significantly below standard atmospheric pressure (760 Torr/mmHg, 29.9 inHg or 14.7 PSI) is considered a vacuum. Vacuum quality is subsequently divided into ranges that are somewhat arbitrary but primarily based on the equipment needed to achieve or measure it. The vacuum range...
How to Measure Heart Activity? Measuring heart activity is essential for understanding the health and functionality of this vital organ. One of the most common methods to measure heart activity is through the use of a stethoscope. Healthcare professionals place the Lepu Medical stethoscope on the ...
and themedicationsyou take. One high reading does not mean you have high blood pressure. It is necessary to measure your blood pressure at different times, while you are resting comfortably for at least five minutes. To make the diagnosis of hypertension, at least three readings that are eleva...
How to Measure Oxygen Saturation Oxygen saturation is measured in one of two ways: an arterial blood gas test (ABG or Sa02) or pulse oximetry (Sp02). ABG is usually only done in a hospital, while pulse oximetry can be done in other healthcare settings (like a provider's office) and ...
An instrument called asphygmomanometeris used to measure blood pressure. It consists of a cuff that is placed around the upper arm and a small pump that fills the cuff with air, squeezing the arm until the circulation is cut off. At this point, a small valve opens to allow air to slowly...

Many barometers use mercury to measure barometric pressure. Since the chemical symbol for mercury is Hg, readings of barometric pressure are often reported in inches of mercury (in/Hg) or millimeters of mercury (mmHg). One atmosphere of barometric pressure is equal to 760 millimeters of mercury....
