­A barometer measures air pressure: A "rising" barometer indicates increas­ing air pressure; a "falling" barometer indicates decreasing air pressure. In space, there is a nearly complete vacuum so the air pressure is zero. 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).
