The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
The ABI is a simple, non-invasive test that measures the ratio of systolic blood pressure in the ankle to the systolic blood pressure in the upper arm. This is based on the idea that if blood pressure readings in the ankle are lower than those in the arm, a blockage in the arteries that provide blood from the heart to the ankle is suspected ...

[citation needed] Similar non-hospital treatment facilities for non-operative vein treatment have existed for some years and are now widespread in many countries. NHS England conducted a review of all 70 vascular surgery sites across England in 2018 as part of its Getting It Right First Time programme. The review specified that vascular hubs ...
Additionally, damage to blood vessels can occur at the site of puncture/injection, and anywhere along the vessel during passage of the catheter. If digital subtraction angiography is used instead, the risks are considerably reduced because the catheter does not need to be passed as far into the blood vessels; thus lessening the chances of ...
Normal pressure range (in mmHg) [1] Central venous pressure: 3–8 Right ventricular pressure: systolic: 15–30 diastolic: 3–8 Pulmonary artery pressure: systolic: 15–30 diastolic: 4–12 Pulmonary vein/ Pulmonary capillary wedge pressure. 2–15 Left ventricular pressure: systolic: 100–140 diastolic: 3–12
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , [ 1 ] but sometimes the femoral artery in the groin or another site is used.
