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).
Good question though. ... Â·. I thing the typical intrathorax pressure -4mmHg dissapears if there is no gases exchange (typical respiratory quotient 0.8 says that there is lack of molecules during gases exchange in lungs, because for each 10 absorbed oxygen molecules are released 8 molecules of carbon dioxide).
