In almost every TV show about an emergency room you probably see an ambulance screeching to a stop with its lights flashing , a gurney being rushed through the corridors and emergency staff racing against time to save a person's kife with only seconds to spare. This scene is possible and occasionally happends , but most of he cases that a typical emergency department sees aren't so dramatic. Let's look at how an ordinary case goes through the normal flow of an emergency room.
When patients arrive at the Emergency Department , they go to triage first. In triage , each patient's condition is prioritized , typically by a nurse. She puts the patient into one of three general categories. The categories are:
・Immediately life-threatening
・Urgent , but not immediately life-threatening
・Less urgent
Categorizing patients is necessary so that someone with a life-threatening condition doesn't have to wait to get care. The triage nurse records the vital sugns (temperature , pulse , respiratory rate , and blood pressure). She also takes a brief history of the patient's current medical complaints , past medical problems , medications and allergies. From this information , the nurse can decide which triage category is suitable.
Registration is the next stage in the ER process. A TV show rarely lets us see this part. It's not exciting , but it is very important. This is where the hospital collexts the patient's personal details and insurance information. Registration is needed to create a clear medical record so that the patient's medical history , lab tests , X-rays , etc. , will all be put on his or her medical chart. That chart can then be checked by doctors , nurses and other medical staff when necessary. Also , this information will be important for creating the hospital bill.
If the patient has a life-threatening situation or arrives by ambulance , the registration stage might be done later at the beside.
Finally , the patient comes to the exam room. The nurse has the person put on a patient gown so that an examination can be done properly. She might also collect a urine specimen at this time.
After the nurse's tasks are fished , the emergency-medicine physician meets with the patient. The physician asks questions t create a more detailed medical history about the present illness , past medical problems , family history , social history , and also takes a close look at all the patient's physical systems. The physician then formulates a list of possible causes of the patient's symptoms. This is called a differential diagnosis. The most likely diagnosis is then determined by th patient's symptoms and the physical examination. If this stage is not enough to create a clear diagnosis , then further diagnostic testa are done.
