Chapter 11 Flashcards
Subdivision of the smaller bronchi in the lungs; made of smooth muscle and dilate or constrict in response to various stimuli
Bronchioles
The use of muscles of the chest, back, and abdomen to assist in expanding the chest; occurs when air movement is impaired.
Labored Breathing
A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients.
Head tilt-chin lift Maneuver
A noninvasive method to quickly and efficiently provide information on a patient’s ventilatory status, circulation, and metabolism; effectively measures the concentration of carbon dioxide in expired air over time
Capnography
A collection of blood in the pleural cavity.
Hemothorax
The process of delivering oxygen to the blood by diffusion from the alveoli following inhalation into the lungs.
Oxygenation
The two nerves that innervate the diaphragm; necessary for adequate breathing to occur.
Phrenic Nerves
Metabolism that takes place in the absence of oxygen; the main by-product is lactic acid.
Anaerobic Metabolism
Thin white bands of tough muscular tissue that are lateral borders of the glottis and serve as the primary center for speech production.
Vocal Cords
Technique to open the airway by placing the fingers behind the angle of the jaw and bringing the jaw forward; used for patients who may have a cervical spine injury.
Jaw Thrust Maneuver
A side-lying position used to maintain a clear airway in unresponsive patients who are breathing adequately and do not have suspected injuries to the spine, hips, or pelvis.
Recovery Position
The amount of air that can be forcibly expelled from the lungs after breathing in as deeply as possible.
Vital Capacity
Occurs when a foreign body partially obstructs the patient’s airway. The patient is able to move adequate amounts of air, but also experiences some degree of respiratory distress.
Mild Airway Obstruction
Visualization of the vocal cords, and thereby placement of the endotracheal tube, that is facilitated by use of a video camera and monitor.
Video Laryngoscope
Space within the chest that contains the heart, major blood vessels, vagus nerve, trachea, major bronchi, and esophagus; located between the two lungs.
Mediastinum
