BACKGROUND Aeromedical transport of critically ill patients requires continued, accurate performance of equipment at altitude. Changes in barometric pressure can affect the performance of mechanical ventilators calibrated for operation at sea level. Deploying ventilators that can maintain a consistent tidal volume (VT) delivery at various altitudes is imperative for lung protection when transpo...

     This study introduces a wearable in-shoe system for real-time monitoring and measurement of the plantar pressure distribution of the foot using eleven sensing elements. The sensing elements utilized in ShrewdShoe have been designed in an innovative way, they are based on a barometric pressure sensor covered with a silicon coating. The presented sensing element has great linearity up to 300...

Altimeter and sea level pressure data from the Geosat mission are analyzed for evidence of inverted barometer response of sea level to atmospheric pressure forcing. Estimates of the inverted barometer coeecient are given for a variety of geographic regions and time scales using various orbit error removal strategies. There is some sensitivity to the orbit error removal method, but the estimated...

Although considered rare, dentists may encounter oral pain evoked by a change in barometric pressure, a condition known as barodontalgia (aerodontalgia). The article reviews the epidemiology, clinical presentation, pathogenesis, diagnostic process and differential diagnosis (including facial and dental barotrauma) of this phenomenon. Preventive measures are described as well.

Global ‘‘ground truth’’ knowledge of solar diurnal S1 and semidiurnal S2 surface pressure tides as furnished by barometric in situ observations represents a valuable standard for wide-ranging geophysical and meteorological applications. This study attempts to aid validations of the air pressure tide signature in current climate or atmospheric analysis models by developing a new global assembly ...

The recognition of barometric pressure was a critical step in the development of environmental physiology. In 1644, Evangelista Torricelli described the first mercury barometer in a remarkable letter that contained the phrase, "We live submerged at the bottom of an ocean of the element air, which by unquestioned experiments is known to have weight." This extraordinary insight seems to have come...
