Respiratory Infections

Respiratory infections are infectious diseases of the respiratory tract that are mostly caused by bacteria and viruses. They cause infections of the throat, sinuses, airway path, and lungs. Respiratory infections are typically divided into two types: upper tract respiratory infection and lower tract respiratory infection.

“Time to scrub in,” says Dr. Hodges. The appendectomy you are about to observe is your second surgical case in surgical technician school. The patient, David Sims, is an 18-year-old male who was healthy until two days ago when he began having severe abdominal pain, fever, and vomiting resulting in a diagnosis of appendicitis. David is in excellent health and has never had surgery before, so you anticipate the procedure to go smoothly. Your instructor asked the anesthesiologist, Dr. Hodges, if you can observe her today during the procedure. “All of the patient’s vital signs and lab work are within normal limits so we are good to go,” says Dr. Hodges as David is brought into the operating room. You help get David ready by applying the heart monitor, oxygen saturation monitor, and blood pressure cuff. After David has been sedated, Dr. Hodges places a special tube down his esophagus to measure his core body temperature and another in his trachea (an endotracheal tube) to help him breathe…
