Sciatica is a medical condition characterized by pain going down the leg from the lower back.[1] This pain may go down the back, outside, or front of the leg. Typically, symptoms are only on one side of the body. Certain causes, however, may result in pain on both sides.
respiratory quotient (RQ) the ratio of the volume of expired carbon dioxide to the volume of oxygen absorbed by the lungs per unit of time. Called also respiratory exchange ratio (above).
The respiratory rate is defined as the number of breaths a person takes during a one-minute period of time while at rest. Recent studies suggest that an accurate recording of respiratory rate is very important in predicting serious medical events; studies also suggest that measurements of respiratory rate are not done as often as they should be, so it's been coined the âignored vital sign.â
