Problem of staff. In this case study, I found out there had human errors on staff. Human error is “A failure of a planned action to achieve a desired outcome” (Human error, n. d.). From the beginning part of the statement, we knew that the untrained anesthesiologist had make a wrong decision to accept the oxygen tank for the intention of saving Michael’s life.

Automatically open and close sliding door should be design and implement as a part of important elements in the design of MRI environment so that medical officers can walk in and out easily through the automatically swing inward and outward door during the emergency period of time. On the other hand, the MRI environment can be set up by using access card for those only authority medical worker to control entry of MRI
