AB  - The  physics  of  flow  underlies  the  behavior  of  all  fluids.  Liquids,  such  as  plasma  and  crystalloid  solutions,  and  gases,  such  as  oxygen  and  sevoflurane,  are  all  considered  to  be  fluids.  Flow  (F)  is  defined  as  the  quantity  (Q,  mass  or  volume)  of  a  given  fluid  that  passes  by  a  certain  point  within  a  unit  of  time  (t),  most  commonly  expressed  in  liters  per  second.  This  relationship  can  be  expressed  by  the  equation  F  =  Q/t.  Fluid  flow  requires  a  pressure  gradient  (ΔP)  between  two  points  such  that  flow  is  directly  proportional  to  the  pressure  differential.  Higher  pressure  differences  will  drive  greater  flow  rates.  The  pressure  gradient  establishes  the  direction  of  flow.
