Airway Anatomy
The flap of cartilage that prevents food and liquid from entering the trachea
What is the epiglottis?
The term for normal, unassisted breathing
What is spontaneous respiration?
One sign of adequate breathing
(Normal rate, regular rhythm, normal depth, effortless breathing, clear/equal breath sounds, normal skin color, normal SpO2)
The maneuver used to open the airway in a patient without spinal injury
What is the head tilt-chin lift maneuver?
The tube that connects the pharynx to the lungs, and is reinforced with C-shaped cartilage rings
What is the trachea?
The structure that connects the larynx to the bronchi
What is the trachea?
The amount of air moved in and out of the lungs in one breath
What is tidal volume?
One sign of inadequate breathing
(abnormal rate, irregular rhythm, shallow breaths, accessory muscle use, diminished/unequal breath sounds, pcc/cyanotic skin, adventitious breath sounds, low SpO2, AMS)
The maximum amount of time for suctioning the oropharynx
What is 15 seconds?
The structure that forms the voice box and houses the vocal cords
What is the larynx?
The two main branches of the trachea that lead into the lungs
What are the bronchi?
The device used to measure a patient's oxygen saturation
What is a pulse oximeter?
The normal range of respiratory rate in an adult
What is 12-20 breaths per minute?
The two types of basic airway adjuncts
What are the oropharyngeal airway (OPA) and nasopharyngeal airway (NPA)?
The point where the trachea divides into the left and right bronchi
What is the carina?
The primary muscle responsible for breathing
What is the diaphragm?
An airway maneuver used for a patient with a suspected spinal injury
What is the jaw-thrust maneuver?
What is cyanosis?
The contraindications for an oropharyngeal airway (OPA)
(conscious, gag reflex)
The three sections of the pharynx
What are the naospharynx, oropharynx, and laryngopharynx?
The tiny structures in the lungs responsible for gas exchange
The volume of air that remains in the lungs after a maximal exhalation
What is residual volume?
Two signs of inadequate artificial ventilation
(minimal/no chest rise, too fast/slow respirations, cyanosis, persistent hypoxia, gastric distention, no improvement)
The percentage of oxygen delivered by a nasal cannula
What is 24% - 44%?
The name of the Adam's apple, sitting just above the cricoid cartilage
What is the thyroid cartilage?
