Dosch, PhD, CRNA and Darin Tharp, MS, CRNA; why? ventilation, heart rate, heart rhythm, pulse quality, blood pressure, MM color, perfusion (CRT). The components and systems as described in this document are typical for a anesthesia gas machine. basic functions of an anesthesia machine. Study 243 Anesthesia Machine flashcards on StudyBlue. lightly touch eyelashes, or medial/lateral canthus and watch for a blink (if conscious the eyelid should close), pinch webbing between toes (HARD); reflex can include complete withdrawal of the limb to tightening of the muscles, lightly touch the cornea of the eye; eyeball should retract into orbit +/- blink response; very subtle- useful in large animals; present at stage 3, plane 2, shine a bright light into the eye; for a normal PLR, pupil should constrict in response. Why is the oxygen flowmeter always the furthest to the right? The students will then answer “to deliver anesthesia gas to a patient.” But again they are wrong. 3). does anemia typically cause low pulse oximeter readings? • Study the airway cart and handle all equipment • Study dosages, indications, and the precautions for all medications as you draw them up • Perform an anesthesia machine check noting the rationale for each step • Use a hands-on anatomy model to learn the airway landmarks Visual Learners Anesthesia Gas Machine - Nurse Anesthesia 531 with Arditti at Oregon Health Sciences University - … Learn key terms, words, definitions, and much more about Anesthesia Machine with our flashcard quizzes more efficient than using a mask, reduces anatomical dead space, reduces risk of aspiration, gives ability to assist respiration if needed, and provides a route for administration of resuscitative drugs.
