There are two major types of circulation problems: restrictions in the blood flow going to an area (arterial), and away from it (venous). The QuantaFlo device measures arterial blood flow to the legs.

Some months ago, my doctor used a QuantaFlo test to measure circulation in my legs. My result was low -- 0.69 versus the normal range of 0.9-1.40. I was not surprised, as poor circulation runs in the ...

Figure 1: Trends in mid-atmospheric geopotential heights. We next explore the extent to which trends in mid-atmospheric circulation patterns have influenced the likelihood of temperature extremes. For ...

(a) Northwest type, (b) Southeast type, and (c) Southern Himalayas type. “C”: cyclonic circulation anomaly. “A”: anticyclonic circulation anomaly. The green arrow indicates moisture transport and its ...

This study investigated the extratropical circulation anomalies responsible for cold surges over the South China Sea in winter. The surge events were identified by the intensity of northerly winds ...

ABSTRACT:This paper analyses atmospheric surface circulation and climatic extremes in the Iberian Peninsula in winter (December–February). Sea level pressure grids (1850–2003) are classified through a ...
