Medical charts are used to to keep record of many things. The things that are kept record of are what procedure is being done, the surgeon performing the procedure the time it started and ended. The monitors and equipment being used, what pre procedures were taken, the agents and fluids being used. The vital signs of a patient are also kept in the medical chart. There is a second part of the chart that is used as a pre anesthesia evaluation. This includes the age, sex, height and weight of the patient, pre procedure vital signs, family history, who provided the family history, lab studies and the signatures of evaluators and the anesthesiologist. This information is provided for both the patient, surgeons, and other doctors that deal with the patient later. Some ethical considerations would be making sure the document is kept safe and used by the correct professionals and since the document isn't typed up officially when in use some words or symbols could be mistaken for other things not intended.
