Airway Management

Chapter 10 Vocabulary

TermDefinition
Adams Apple the projection at the front of the neck formed by the thyroid cartilage of the larynx, often prominent in men
Agonal respirations gasping type of respirations that have no pattern and occur frequently; a sign of cardiac or respiratory arrest
Alveolar Ventilation the amount of inspired air that reached the alveoli of the lungs
Alveoli the air sacks in the lungs Pl of alveolus
Automatic Transport ventilator a positive pressure ventilation device that delivers ventilations automatically
Bag Valve Mask positive ventilations devise that consist of a bag with a nonrebreather valve and a mask, the bag is squeezed to deliver ventilations
Bilaterally On both sides
Bilevel positive airway pressure a form of nonivasive positive pressure ventilation. The BIPAP device delivers a continuous flow of air under pressure
Bradypnea a breathing rate that is lower than normal
Bronchi the two main branches leading from the trachea to the lungs providing the passageway for air movement
Bronchioles small branches of the bronchi
Carina the point at which the trachea splits into the left and right main stem bronchi
Chemoreceptors receptors that constantly monitor the arterial content of oxygen, carbon dioxide, and the blood PH
Continuous Positive Airway Pressure The CRAP device delivers a continuous flow of air under pressure
Cricoid Cartilage The most inferior portion of the larynx and only full cartilaginous ring of the upper airway. It is felt immediately below the Thyroid Cartilage
Cricoid Pressure Pressure applied to the Cricoid Cartilage to compress the esophagus. Also called "Sellick Maneuver"
Crossed Finger Technique A tech and in which the thumb and index fingers on the jaw making a snapping motion to open the jaw
Crowing A sound similar to that of a cawing crow that indicates that the muscles around the larynx are in spasm and beginning to narrow the opening to the trachea
Cyanosis A blue-gray color of the mucous membranes and/or skin which indicates inadequate oxygenation or poor perfusion
Dead air space anatomical areas in the respiratory track where the air collects during inhalation but no gas exchange
Deoxygenated Containing low amounts of oxygen, as with Venous blood
Diaphram The major muscle of respiration that separates the chest cavity from the abdominal cavity
Epiglottis a small leafed shaped flap of cartilaginous fissue located posterior to the root of the tongue (protects trachea from food/water)
Esophagus passageway at the lower end of the pharynx that leads to the stomach
Exhalation/Expiration The passive process of breathing air out the lungs
External Respiration The gas exchange process that occurs between the alveoli and the pulmonary capillaries
Flow-restricted,oxygen-powered ventilation Device a device that consist of a ventilation valve and trigger or button and is driven by oxygen
French Catheter- Scott Catheter a thin tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure
Gastric Distention Inflation of the stomach
Gurgling a gurgling sound that indicates a fluid is in the mouth or pharynx
Hard Catheter - Rigid Catheter a rigid plastic tube that is a part of a suctioning system commonly refereed to as a tonsil tip or tonsil sucker
Head-tilt, chin-lift manuver a manual technique used to open airway
Hemoglobin a complex protein molecule found on the surface of the red blood cells that is responsible for carrying oxygen
High-pressure regulator a one gauge regulator that is used to power the flow restricted, oxygen powered ventilation device. Flow rate CAN'T be adjusted
Hypofusion Shock -SHOCK the insufficient delivery of oxygen and other nutrients to some of the body's cells inadequate elimination of carbon dioxide and other waste that result from inadequate circulation of blood.
Hydoxemia a low oxygen content in arterial blood
Hypoxia a reduced oxygen delivery to the tissue
Inhalation/Insipiration The active process of breathing air into the lungs
Intercostal Muscles The muscles in between the ribs
Internal resperations the gas exchange process that occurs between the cells and the cappilaries
Jaw-thrust maneuver a maneuver technique used to open the airway in the patient with a suspected spinal injury
Laryngectomy A surgical procedure in which a patients larynx is partially or completely removed. A Stoma is created
Larynx structures that house the vocal cords and is located inferior to the pharynx and superior to the trachea
Lower Airway The portion of the respiratory system that extends from the trachea to the alveoli of the lungs
Minute Volume the amount of air you breathe in one minute
Mucous Membrane A thin layer of tissue that lines various structures within the body
nasal cannala the oxygen delivery device that consists of two prongs that are inserted into the nose of the patient. 22-44% oxygen received.
Nasopharyngeal airway a curved, hollow rubber tube with a flange or flare at the top and a bevel at the distal end that is inserted into the nose
oropharynx the central portion of the pharynx lying between a soft plate and the epiglottis with the mouth as the opening
oxygen humidifier a container that is filled with sterile water and connected to the oxygen regulator to add moisture
Oxygenated Containing high amounts of oxygen, as with arterial blood
Oxygenation the form of respiration where the blood uses its oxygen then it gets oxygen as it runs through the capillaries
Parietal pleura the outermost pleural layer that adheres to the chest wall
Partial rebreather mask an oxygen delivery device similar to a non breather but the patient breathes 2/3 of the bag oxygen and the rest from the air
Patent airway an airway that is open and clear of any obstructions
Pharynx the throat, or passageway for air from the nasal cvity to the larynx and passage way for food
Pleura two layers of connective tissue that surrounds the lungs
Pleural Space a small space between the visceral and parietal pleura that is at pressure and filled with the serous fluid
Positive pressure ventilation method of aiding a patients whos breathing is inadequate by forcing air into his lungs
Pressure regulator a device that reduces the high pressure in the oxygen cylinder to a safe range 1-15 lpm
Residual Volume the air remains in the lungs after a maximal exhalation
Respiration the exchange of gasses in the organs (lungs, capillaries)
Respiratory aresst Complete stoppage of breathing - Also called Apnea
Respiratory Distress Increase respiratory effort resulting from impaired respiratory function, while tidal volume and respiratory rate
Respiratory Failure Insufficient respiratory rate and or tidal volume
Respiratory Rate The number of breathes taken in one minute
Retractions depressions in the neck, above the clavicles between the ribsXXXXXXXX
Rigid Catheter A rigid plastic tube that is part of a suctioning system
Serous Fluid Fluid that acts as a lubricant to reduce the friction between the parietal and visceral pleura
Simple Face Mask A barrier device used in infection control.
Snoring is the sound that is heard when the base of the tongue blocks the airway
Soft catheter flexible tubing that is pat of the suctioning system also called french catheter
Stoma a permanent surgical opening to the neck and trachea
Stridor A harsh, high pitched sound heard on inspiration that indicates swelling of the larynx or obstruction of the airway
Tachypnea breathing that is faster then normal
Therapy regulator A device that controls the flow and pressure of oxygen from the tank to allow for a consistent flow of oxygen
