Total critical care time [] minutes. This time does not include time spent on separately billable procedures. Due to a high probability of clinically significant, life threatening deterioration, the patient required my highest level of preparedness to intervene emergently and I personally spent this critical care time directly and personally managing the patient. This critical care time included obtaining a history; examining the patient; pulse oximetry; ordering and review of studies; arranging urgent treatment with development of a management plan; evaluation of patient's response to treatment; frequent reassessment; and discussions with other providers.
