Oxygen difluoride is a chemical compound with the formula OF2. As predicted by VSEPR theory, the molecule adopts a bent molecular geometry. It is a strong oxidizer and has attracted attention in rocketry for this reason. [ 5] With a boiling point of −144.75 °C, OF 2 is the most volatile (isolable) triatomic compound. [ 6]
Blood pressure measurement. A medical student checking blood pressure using a sphygmomanometer and stethoscope. Arterial blood pressure is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure. [ 1] Blood pressure values are generally reported in millimetres ...
Blood pressure ( BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Central venous pressure ( CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system. CVP is often a good approximation of right atrial pressure (RAP), [ 1] although the two terms are not ...
Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80." He went on to call the test "life-saving" and "the single ...
Ambulatory blood pressure, as opposed to office blood pressure, is the blood pressure over the course of the full 24-hour sleep-wake cycle. Ambulatory blood pressure monitoring ( ABPM) measures blood pressure at regular intervals throughout the day and night. It avoids the white coat hypertension effect in which a patient's blood pressure is ...
Blood gas tension refers to the partial pressure of gases in blood. [1] There are several significant purposes for measuring gas tension. [2] The most common gas tensions measured are oxygen tension (P x O 2 ), carbon dioxide tension (P x CO 2) and carbon monoxide tension (P x CO). [3] The subscript x in each symbol represents the source of the ...
