<prompt> Blood gas paition coefficient of anaesthetic agent tells aboutSolubility in bloodPotency of agentTime lag of induction of anaesthesiaAll of the above  <response>: Time lag of induction of anaesthesia Blood gas solubility blood gas paition coefficient is the best indicator for induction and recovery. Agent with less blood gas solubility will have fast induction and recovery while agents with less blood gas solubility will have slow induction Ref Katzung 12th ed.
