Anesthesia Equipment and Monitoring
| Question | Answer |
|---|---|
| When mixing N2O and O2 what percentage is considered "critically low"? | 20% |
| What does a vaporizer do? | converts liquid anesthetic into gasses suitable for delivery with other gases through the anesthesia machine |
| How often should vaporizers be checked? | Periodic maintenance and calibration should be completed according to manufacturers recommendations |
| What does a Ventilator do? | Breathes for the patient. (with positive and negative pressures moving anesthetic gasses into and out of the lungs.)` |
| how often should the N2O/O2 machine be checked for patency and leaks? | daily |
| What is a scavenger system? | a means for reducing the levels of noxious gasses out of opertories for the well being of those chronically exposed. |
| What color cylinder is oxygen kept in ? | Green |
| What color cylinder is Nitrous kept in? | Blue |
| What color cylinder is Carbon Dioxide kept in? | Grey |
| What color cylinder is compressed air kept in? | Yellow |
| What color cylinder is Nitrogen kept in? | Black |
| What color cylinder is Helium Kept in? | Brown |
| When should you shut off cylinders and pressures and gauges reduced to zero? | after the last patient |
| what psi does a full O2 tank typically read? | 2000 psi |
| What does a full N2O tank typically read? | 750 psi |
| What will an almost empty N2O tank read? | 750 psi |
| maintiaing the patients airway begins with what three things? | 1. Head position 2. N2O/O2 delivery 3. Suction |
| two methods of positioning the patients head for open airways are? | 1. Head tilt/Chin Lift 2. Jaw Thrust |
| 2 ways to deliver N2O/O2 | 1. Nasal Mask or Hood (covers nose only) 2, Nasal prongs or cannulas (inserted into the nares (nostrils) with out covering the nose) |
| Should you have to suction out the patient prior to the induction of anesthesia? | YES- to remove accumulated secretions from the pharynx. |
| In the event of an airway emergency what is the initial intervention implemented ? | Bag/valve/mask |
| what do you do if the tongue continues to obstruct the airway during the airway emergency and a bag cannot correct the situation? | a tongue suture can be placed, a nasopharyngeal airway or an oral pharyngeal airway may be necessary. |
| Which airway can be placed and tolerated well by most patients whether awake or sedated? | Nasopharyngeal |
| What is an LMA? | Laryngeal Mask Airway |
| The LMA sits tightly over the top of what? | Larynx |
| Does an LMA protect the patient from aspiration of regurgitated material.? | No |
| after inserting the endotracheal tube why do you listen to the left and right side of the chest.? | to make sure that the tube was not inserted into the right mainstream bronchus. |
| what sound do you hear if the trach tube is entered into the esophagus? | gurgling |
| What is pharyngitis | sore throat |
| There are 8 airway adjuncts, name them | 1. ambu bag 2. Tongue traction suture 3. Nasopharyngeal tube 4. Oropharyngeal airway 5. Laryngeal mask (LMA) 6. Endotracheal intubation 7. Combitube 8. Cricothyrotomy |
| what is the last step after all else fails to open an airway? | Surgical airway |
| what is the quickest easiest surgical airway to place? | Cricothyrotomy |
| where is the cricothyrotmy performed? | between the thin membrane between the cricoid and thyroid cartilages of the larynx. |
| what should only be considered on the unconscious patient? | oral airway, LMA, endotracheal tube and combitube |
| what is the elettrocardiograph | device used to monitor the electrical activity of the heart. |
| when do you use a defibrillator | venticular fibrillation. |
| what does AED stand for | automatic external defibrillator |
| what are the two types of AEDs | automatic and semi automatic |
| Statistics show that the AED can eliminate ventricular fibrillation in what percentage of the cases on the first shock | 85% |
| how often should the lines and cuffs be checked on a BP monitor | weekly |
| name 3 ways to monitor ventilation through observation | chest rise, anesthesia bag, color |
| what is Cyanosis | bluish tinge in the color of the mucous membranes, skin and nail beds. |
| Name the ways to monitor ventilation thoughout a proceedure | observation, pretracheal stethoscope, pulse oximeter, capnograph/capnometer |
| how big of a time lapse can a pulse ox have | 30-90 seconds |
| what can monitor the patients ventilation in real time | capnometer or capnograph |
| what is the required monitoring for moderate(conscious) sedation patients, all deep sedation patients and general anesthesia patients? | continuous ECG or EKG |
| what is malignant hyperthermia | the inability to regulate the body's temperature |
