Page 1 Defining Anesthesia •The word anesthesia originated from the Greek term anaisthaesia, meaning “insensibility”; is used to describe the loss of sensation to the body in part or in its entirety. Marc A. Sherwin, MD, James B.

Terms of Use each 100ml of blood contains 20ml of O2, free molecules in plasma (0.3ml), bound to hemoglobin (19.7ml). Take the time and study the manuals, learn your anesthesia machines. Once the patient is completely recovered and only in small amounts, What factors influence the length of the recovery period, Length of anesthesia, type of anesthesia used, overall health of patient, breed of patient, body temperature, List 4 reasons to continue O2 administration during the recovery period, Maintains open aiways, helps reinflate atalectic lungs, helps prevent hypoxemia due to shivering, helps scavenge waste gases. yes, the canister is ineffective at high flow rates and does not absorb nitrous oxide, the total volume of the conducting airways from the nose or mouth down to the level of the terminal bronchioles, where the air doesn't come to the alveoli of the lungs. Study Anesthesia Machine Flashcards Flashcards at ProProfs - Start studying the Anesthesia Machine with these flashcards quizzes. the build up of CO2 does not trigger respiratory effort as it would in an awake animal, collapsing of alveoli (no gas exchange occurs in the area), "bagging" patient every few minutes- close popoff valve and squeeze rebreathing bag. what are the three basic types of anesthetic gas scavenging systems? what are the four complications of general anesthesia that almost always occur? what is the major driver or the respiratory reflex? If your institution subscribes to this resource, and you don't have a MyAccess Profile, please contact your library's reference desk for information on how to gain access to this resource from off-campus. this space fills with inspired air at the end of each inspiration, but this air is exhaled unchanged. The students will then answer “to deliver anesthesia gas to a patient.” But again they are wrong. We need to bury the concept that anesthesia is simple mathematics, giving so many mg per lb., with the only question being the weight of the animal. it is possible to administer resuscitative drugs via the endotracheal tube. This guide can provide a framework for viewing anesthetic management as the critical cornerstone of quality veterinary medicine that it should be. Pulse oximetry is a noninvasive method used to determine oxygen levels in arterial blood. depth of anesthesia can be adjusted rapidly once patient is anesthetized, fast recovery, useful for fractious patients, waste gas released into room, increased patient stress, predisposes to cardiac arrhythmias, increased induction time, suffocate patient, hard to monitor patient inside chamber, risk of aspiration, urinate / defecate on self, harm to patient/restrainer/anesthetist, only useful for smaller animals. Contemporary anesthesia machines have two sources of gases: the wall outlet and E-cylinders attached to the machine itself. which type of scavenging systems does OSU-OKC have? what factors influence the length of the recovery period? why? hospital design, fill anesthetic vaporizers at the end of the day immediately before personnel leave the building, proper maintenance of anesthetic machines, limit use of induction chamber, leave patient connected to anesthetic machine with only oxygen flowing until most recovered, use of scavenging systems. A. • 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 aggressively treat with col water towels and drugs (dantrolene). 7. I’ve learned that without the fundamentals it is difficult to completely understand how anesthesia machines are supposed to perform. Study 243 Anesthesia Machine flashcards on StudyBlue. what is the most common cause of death during the recovery period? Disclaimer: These citations have been automatically generated based on the information we have and it may not be 100% accurate. when is the recovery period considered complete? what is the normal pH of blood in anesthetized animals? what effect does general anesthesia have on the respiratory reflex? In susceptible individuals, these drugs can induce a drastic and uncontrolled increase in skeletal muscle oxidative metabolism, which overwhelms the body's capacity to supply oxygen, remove carbon dioxide, and regulate body temperature, eventually leading to circulatory collapse and death if not treated quickly. Biomed Certification Study Guide By Dave Harrington vi PREFACE Dave Harrington compiled this biomed study guide for classes in the Northeast, using some of the material for his ICC prep column in 24 X 7. requires less anesthetic agent and slows liver metabolism of drug which leads to slow recovery, list some methods that can be used to help avoid/lessen hypothermia, insulate patient from cold surgery table/recovery surface, wrap patient in warmed towels/blankets, administer warmed IV fluids, use warmed irrigation/lavage solution in a body cavity. which method should be used for small patients or patients with extreme hypotension? obstruction can cause gas to build up within the anesthetic circuit and increases pressure patient must breath against (similar to effect of closing pop-off valve). what are the characteristics of the maintenance phase of anesthesia? what instrument is used to measure the amount of oxygen in the blood? why is this significant? remove endotracheal tube as soon as swallowing begins. Students should be able to apply basic ASA monitors and have an understanding of the function of each. which form is most CO2 found? D. All of the above. This article will guide the reader through a historical over-view of anesthetic gas monitoring technology and market evolution, culminating in today’s state-of-the-art products. 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. Butterworth J.F., IV, & Mackey D.C., & Wasnick J.D.(Eds. prior to removing the tube, once patient has swallowed once, deflate the cuff to prevent damage to the trachea and larynx, check inside mouth to ensure that there is not a fluid build up (if there is only slightly deflate cuff and gently/slowly remove tube to bring up that liquid) if it's possible have patient sternal with head tilted downward and gently pull the tube out, describe how you would handle a patient that vomits during recovery after extubation, Get patient sternal, elevate hind quarters, lower head, immediately remove vomitus from area, clean out oral cavity if possible including sweeping pharyngeal area.
