| ________ is a small horseshoe shaped bone to which the jaw, apiglottis and thyroid cartilage attach as well | hyoid bone |
| what is the superior border of the glotic opening called | epiglottis |
| What is the anatomic space or ''pocket'' located between the base of the tongue and the epiglottis called | vallecula |
| a sheild shaped structure formed by 2 plates that join in a v-shape to form tha adams apple is called | thyroid cartilage |
| What forms the lowest portion of the larynx | cricoid cartilage |
| the site for emergency surgical access to the airway is called | cricothyroid membrane |
| A spasmodic closure of the vocal cords, which seals of the airway is called | laryngospasm |
| An et tube that is inserted to far will often come to lie in the right mainstem bronchus. Why? | Because the right bronchus is somewhat shorter and streighter then the left bronchus |

| What is the name of the outer lining of the lungs | visceral pleura |
| Alveoli are lined with a proteinaceous substance known as | Surfactant |
| If the amount of pulmonary surfactant is decreased or the alveoli are not inflated, they will collapse. A condition known as | atelectasis |
| what 2 types of motor nerves effect breathing | Phrenic nerves, intercoastal nerves |
| The exchange of gases between the lungs and the blood cells in the pulmonary capillaries is referred to as | External respiration |
| The exchange of gases between the blood cells and the tissues is referred to as | Internal respiration |
| Gas exchange in the body occurs by _______ a process in which a gas moves from an area of higher concentration to an area of lower concentration | diffusion |
| ~ how much of the bodies total oxygen is bound to the hemoglobin | 97 % |
| Carbon Monoxide has a much greater affinity for hemoglobin then oxygen. How much greater | 250 times |
| A deficiency of red blood cells, that results in a chronically decreased ability of the blood to carry oxygen. Name the desease | Anemia |
| If CO2 production exceeds the body's ability to eliminate it by ventiliation th co2 rises causeing a condition known as | hypoventilation |
| When co2 elimination exceeds co2 production this causes a condition known as | Hyperventilation |
| What is hypercarbia | a co2 build up in the blood |
| what is hypocarbia | a low level of co2 in the blood |
| What is dyspnea | difficulty breathing |
| what is hypoxemia | a decrease in arterial o2 levels |
| what is hypoxia | a lack of oxygen to the body's cells and tissues. |
| What is anoxia | an absence of oxygen resulting in cellular and tissue death |
| What is orthopnea | positional dyspnea |
| Name some protective reflexes of the airway | coughing, sneezing, and gagging |
| Name a fairly reliable indicator of a gag reflex | eyelash reflex |
| What does sighing do to the alveoli | it hyperinflates the lungs, therby reexpanding atelectatic alveoli |
| What is carboxyhemoglobin | hemoglobin with carbon monoxide attached |
| What is oxyhemoglobin | hemoglobin with oxygen attached |
| What position would you place a patient with a decreased LOC but able to maintain their own spontaneous airway and breathing adequately | recovery position |
| Airway obstructions cause by larngeal spasm or edema MAY be relieved by what? | Aggressive ventilation, a forceful upward pull of the jaw to reposition the airway, and certain cases muscle relaxants. |
| Aspiration significantly increases | mortality |
| What is the maximum suction time in an adult | 15 seconds. |

| ventilation rate in an apneic adult patient without a pulse | 8-10 breaths a minute |
| ventilation rate in an apneic pediatric patient with a pulse | 12-20 breaths a minute |
| ventilation rate in an apneic pediatric patient without a pulse | 8-10 breaths a minute |
| Name one of the most common mistakes in proceeding with advanced airway management | proceeding with advanced management without first trying bls airway |
| How long should you ventilate before attempting intubation | 2-3 minutes with 100% O2 |
| What size ET tube will the normal adult female require | 7.0 - 8.0mm |
| What size ET tube will the normal adult male require | 7.5 - 8.5mm |
| What can you use as a good approximation of the diameter of the glottic opening | the internal diameter of a nostril |
| What is the streight blade called | miller |
| what is the curved blade called | macintosh |
| Medications that can be given via the ET tube follow what numonic? | LEAN Lidocain, Epinephrine, Atropine, Narcan |
| Meds given via the et tube should be given how many times their standard dose | 2-2.5 times |
| When attempting intubation don't allow your O2 sat to drop below _____ | 95% |
| Before intubating always check that your bulb on your blade is ______ | Bright, White, Steady and Tight |
| What is the BURP maneuver | Backward Upward Rightward Pressure |
| Immediately after successful intubation you should hyperventilate your patient for how long, and why | 30 sec - 1 minute to eliminate any accumulated Carbon Dioxide |
| capnography may be inaccurate in what patients | Patients in cardiac arrest, who are severly acidotic, or patients eliminating minimul carbon dioxide |
| How much smaller should the ET tube being inserted into a nostril be, then the nostril it is going into | 1-1.5mm |
