Peak flow meter (health) and playa (sh)


Peak flow meter (health)


A portable, inexpensive, hand-held device used to measure how air flows from lungs in one "fast blast" to measure the ability to push air out of the lungs. Measurements with a peak flow meter help the patient and physician monitor your asthma. These measurements can be important and help your physician prescribe medicines to keep asthma in control.







playa (sh)




or pan or flat or dry lake

Flat-bottomed depression that is periodically covered by water.

Playas occur in interior desert basins and adjacent to coasts in arid and semiarid regions. The water that periodically covers the playa slowly filters into the groundwater system or evaporates into the atmosphere, causing the deposition of salt, sand, and mud along the bottom and around the edges of the depression.
