In a study of 25 million ambulatory visits by COPD patients, temperature, wind speed, air pressure at sea level, and humidity had a significant influence in 1–2% of the ambulatory visits (Ferrari et al. 2012). The weather is for a large part determined by barometric pressure (Barry and Chorley 2009).One of the effects of barometric pressure changes is a decrease in oxygen in your blood. This happens specifically when a barometric pressure drop occurs. When the air pressure drops, your body may compensate by causing the blood vessels in your brain to dilate. The goal of this dilation is to increase the flow of oxygen to your brain.Web app that graphs the barometric pressure forecast and history, anywhere in the world.
