This one is a little less silly than it sounds. Medicine is getting all the more complex as technology advances and we get better at testing for different conditions. This means a lot of people pay excessive attention to the numbers, and not to their patient, often forgetting the basic principles especially in an emergency situation.
Don’t forget the basics, and use your common sense. Keep the blood on the inside, keep the air moving in and out and your patient probably will survive until someone can help you.
