An experiment to assess psychomotor performance before and after forward-facing (-Gx) impact was conducted using the AFAMRL Horizontal Decelerator Facility. There were 10 volunteer subjects who participated in 50 tests at 4 impact levels (0 G or sham, 8 G, 10 G, and 12 G). Two initial head positions were explored at the highest impact level. The manikin psychomotor task, a complex reaction time...

A single-breath technique of inhalational induction of anaesthesia allows intravenous induction agents to be avoided. We have investigated recovery from anaesthesia in 40 daycase patients, using tests of psychomotor function. Patients anaesthetised with inhalational induction awaken earlier than those who receive thiopentone, but not significantly earlier. There were no significant differences ...
