CDCA Nitrous Oxide, Questions and answers, Graded A+. 2022 update Document Content and Description Below CDCA Nitrous Oxide, Questions and answers, Graded A+. 2022 update Is nitrous oxide a drug? - Yes 2 main purposes of nitrous oxide - Ease pain Minimize anxiety How long has nitr ous oxide been around? - 1700 's Who was a strong advocate for nitrous oxide in the mid 1800s? "Father of Anesthesia" - Dr. Horace Wells What did dr. Wells routinely use nitrous oxide for? - Extractions What provided a Segue of other agents in general anesthesia? - Nitrous oxide How is conscious sedation used in healthcare? - Same-day procedures and out-patient clinics/facilities offer options to patients that are less expensive and less time intrusive Indications for the use of nitrous oxide sedation - 1. reduce pain 2. alleviate fear and anxiety 3. analgesia and/or pain modulation 4. anxiolytic 5. suppression of hyperactive oral gag reflex Contraindications for the use of nitrous oxide - 1. pregnancy 2. history of or current drug/substance abuse 3. inability to communicate 4. problematic situations due to gas expansion 5. bleomycin sulfate therapy 6. COPD 7. psychosis and other mental illness 8. upper respiratory condition/sinus infection Gas properties of nitrous oxide - Tightly bound molecule of nitrogen and oxygen that does not separate in the body Flammable or non flammable? - Non flammable by Nature Stored as a______ in cylinders and pressurized at ______ PSI - Liquid 750 What color are nitrous oxide cylinders? - Blue What color are oxygen cylinders? - Green Are large or minimal amounts of nitrous oxide dissolved in the blood? - Minimal amounts Does nitrous oxide cross the blood-brain barrier? - Yes, easily Oxygen - Combustible , therefore should not come in contact with a hydrocarbon Source such as a grease or lubricant Oxygen is compressed as a gas into cylinders at ______ PSI - 2000 Is nitrous oxide metabolized in the liver? - No Nitrous oxide diffuses quickly out of the blood and back into the lungs to exit the same way it entered. - True How long should you oxinate a patient postoperatively? - 3 - 5 minutes of 100% oxygen Tidal volume - The volume of gas inspired into an individual's long Why is tidal volume important? - Because it determines the amount of flow necessary to maintain the patient Comfort during respiration through the nasal hood and Achieve sedation Inadequate flow to the patient - A feeling of suffocation Too much flow to the patient - Likely to leak out of the hood and blow across the patient's face and be wasted Minute volume - The product of tidal volume X the respiratory frequency The lung capacity of an average adult - 500 mL If 500 mL is multiplied by an average minute respiratory rate of 12 - 16, the result is approximately 6 - 7 L/min. What is an average minute volume for a child? - 3 - 5 L/min Armamentarium stations can be (2) - Centralized Portable systems Units are designed to insure a minimal delivery of nitrous. What
