HCB 102 4 1 1 Respiratory System
Apnea - answersNo breathing
Cyanosis - answersA bluish, purplish color of the skin due to insufficient oxygen levels
in the blood
Diffusion - answersA process by which molecules move from HIGH to LOW
concentration
Dyspnea - answersDifficult and labored breathing; shortness of breath
Hypoxia - answersA deficiency of oxygen reaching the tissues of the body. Low O2
levels. Leads to cyanosis
Intercostal - answersSituated or extending between the ribs.
Inter=between
Costal=ribs
Respiratory distress - answersIncreased work of breathing; a sensation of shortness of
breath
Respiratory failure - answersThe reduction of breathing to the point where oxygen
intake is not sufficient to support life.
Retractions - answersPulling in the skin and soft tissue between the ribs when
breathing.
Larynx - answersContains vocal cords (voice box)
Connects pharynx with Trachea.
Cricoid cartilage - answersLower portion of larynx
Trachea - answersTube that carries inhaled air from the larynx toward the lungs
Bronchi - answersTrachea splits into 2 branches (1 to each lung)
Bronchial Tree consists of: - answers-Trachea
-Primary bronchi
-Secondary bronchi
-Tertiary bronchi
-Bronchioles
-Terminal bronchioles
, Chemoreceptors - answersDetect increasing levels of carbon dioxide as well as low
levels of oxygen
Respiration - answersExchange of gases between he alveoli and the blood (external
respiration) and between the blood and the cells (internal respiration)
Pulmonary respiration - answersDiffusion of oxygen and carbon dioxide that takes place
between the alveoli and circulating blood
Cellular respiration - answersDiffusion of oxygen and carbon dioxide that takes place
between cells and circulating blood
Alveoli - answersSmall sacs within the lungs where gas exchange occurs
2 Q's assessing airway - answers-"Is the airway open?"
-"Will the airway stay open?"
Signs of Inadequate airway - answers-No air movement
-Foreign objects; blood, vomit, broken teeth
-Difficult speaking
-Unusual hoarse
-Chest movement=absent, minimal, uneven
2 ways to opening the airway - answers-Head-tilt, chin lift
-Jaw thrust (ONLY if head, neck or spine injury)
Causes of Inadequate breathing - answers-Trapped in a fire
-Overdose on a drug
-Heart attack, stroke, shock
-Cyanosis ad altered mental status
-Prevent hypoxia from becoming worse by administering oxygen
