1. ventilation - ANSWER ✔ movement of air into and out of lungs,
regulation in aveoli
2. perfusion - ANSWER ✔ ability of cardiovascular system to pump
oxygenated blood to tissues and return deoxygenated blood to lungs
3. pulmonary system - ANSWER ✔ lungs, airways, chest walls, blood vessels
4. hypoxia - ANSWER ✔ low oxygen in tissues
5. hypoxemia - ANSWER ✔ low oxygen in blood
6. hypoventilation - ANSWER ✔ ventilation inadequate to meet oxygen
needs or eliminate enough CO2, caused by collapsed alveoli
7. hyperventilation - ANSWER ✔ increased respiratory rate which causes
excess CO2 elimination, anxiety/infection/drugs/acid-base imbalance induce
hyperventilation

(heart failure), myocardial ischemia (myocardial infarction), impaired
valvular function (obstructed blood flow, regurgitation), left-sided heart
failure (decreased cardiac output, pulmonary congestion), right-sided heart
failure (distended jugular veins, peripheral edema), hypovolemia (decreased
circulating blood flow)
11.sinus tachycardia - ANSWER ✔ regular rhythm, fast rate of 100-180 bpm

cardiac rate of rhythm, no identifiable P wave
14.heat and cold therapy - ANSWER ✔ body responses (systemic - heat loss
or conservation mechanisms, local - stimulation of nerve endings, adaptive
process), order required
15.local effects of heat and cold therapy - ANSWER ✔ heat (reflex
vasoconstriction)
cold (reflex vasodilation)

purulent (thick, yellow, green, tan, brown)
serosanguineous (pale, pink, watery; mix of clear and red fluid)
sanguineous (bright red; indicates active bleeding)
