  Title: STS-31 MS Sullivan, MS McCandless, DSO 462 medical device on OV-103 middeck
  Description:
  STS-31 Mission Specialist (MS) Kathryn D. Sullivan applies a gel to a 
  transducer while MS Bruce McCandless II uses a central venous pressure 
  mouthpiece on the middeck of Discovery, Orbiter Vehicle (OV) 103.  The 
  crewmembers are conducting Detailed Supplementary Objective (DSO) 462, 
  Non-Invasive Estimation of Central Venous Pressure.  After preparing the 
  transducer, Sullivan will apply it to McCandless' juggler.  DSO 462 will 
  measure the physiological adaptation to the headward shift that occurs in 
  microgravity.  This non-invasive technique of determining central venous 
  pressure uses the mouthpiece with varying resistance and a probe that 
  utilizes Doppler flowmetry.
