Respiratory System Flashcards
What term means no breathing?
apnea
What term describes a bluish or purplish color of the skin due to insufficient oxygen levels in the blood?
cyanosis
What is the process by which molecules move from an area of high concentration to an area of low concentration?
Diffusion
What term describes difficult or labored breathing?
Dyspnea
What term describes a deficiency of oxygen reaching the tissues of the body?
Hypoxia
What term means situated or extended between the ribs?
intercostal
What term means increased work of breathing; a sensation of shortness of breath?
Respiratory distress
What term describes the reduction of breathing to the point where oxygen intake is not sufficient to support life?
Respiratory failure
What term describes the pulling in of the skin and soft tissue between the ribs when breathing?
retractions
What structure loses over the glottis to prevent food and foreign objects from entering the trachea?
Epiglottis
What structure contains the vocal cords and connects the pharynx with the trachea?
Larynx
What does the bronchial tree consist of?
trachea, primary bronchi, secondary bronchi, tertiary bronchi, brochioles and terminal bronchioles
What are the small sacks within the lungs where gas exchange occurs?
Alveoli
What structure divides the chest cavity from the abdominal cavity?
Diaphragm
What type of process is inhalation?
Active
What does the diaphragm do when we inhale?
Contracts
What type of pressure is generated when we inhale?
Negative
What type of process is exhalation?
Passive
What type of pressure is generated when we exhale?
Positive
What structure in the body detects increasing levels of carbon dioxide as well as low levels of oxygen?
Chemoreceptors
What term describes the process of inhaling and exhaling?
Ventilation
What term describes the diffusion of oxygen and carbon dioxide that takes place between the alveoli and circulating blood?
Pulmonary Respiration
What term describes the diffusion of oxygen and carbon dioxide that takes place between the cell and circulating blood?
Cellular respiration
What is the best position for airway evaluation, opening the airway, and artificial ventilation in the patient with a diminished mental status?
Supine
How do you open the airway when a head, neck or spinal injury may be present?
Jaw thrust
How do you place the hand on the patient when performing the head tilt - chin lift?
one hand on the forehead, one hand on boy area of patient’s lower jaw
