Complete Solution
Dyspnea - ANSWER The feeling of being unable to get enough air
-breathlessness, air hungry, SOB
-Labored breathing
Diffuse of focal pulmonary diseases
Disturbances of ventilation - ANSWER What are the causes of dyspnea?
flaring of nostrils, accessory muscle use, retraction of intercostal spaces -
ANSWER What are the signs/symptoms of dyspnea?
common in pulmonary disorders, caused by pulmonary congestion -
ANSWER What are the characteristics of dyspnea on exertion?
Dyspnea when lying down - ANSWER What are the characteristics of
orthopnea?
Wake up at night gasping for air - ANSWER What are the characteristics of
paroxysmal nocturnal dyspnea?
Increased ventilatory rate, very large tidal volume and no expiratory pause -
ANSWER What are the characteristics of kussmaul respiration?
lungs stiffen, compliance decreased, small tidal volumes - ANSWER What are
the characteristics of restricted breathing?
alternating periods of deep, shallow breathing - ANSWER What are the
, characteristics of Cheyne-Stokes respirations?
diseases that cause chronic hypoxemia - ANSWER What type of diseases
cause clubbing?
cough - ANSWER a protective reflex that cleanses the lower airways by
explosive expiration
resolves in 2-3 weeks of onset or resolves with treatment - ANSWER What
are the characteristics of an acute cough?
Lasts longer than 3 weeks - ANSWER How long does a chronic cough last?
hemoptysis - ANSWER Coughing up blood
lung cancer - ANSWER What is hemoptosis a warning sign for?
increased arterial CO2, hypoventilaion of alveoli, decreased drive to breath -
ANSWER What are the characteristics of hypercapnia?
reduced oxygenation of cell in tissues, low CO - ANSWER What are the
characteristics of hypoxia?
Hypoxemia - ANSWER A reduction of oxygenation of arterial blood
proper balance between amount of air getting into alveoli (V), and amount of
blood perfusing capillaries around alveoli (Q) - ANSWER What two things are
diffusion of oxygen dependent on?
V/Q mismatch - ANSWER The most common cause of hypoxemia
normal blood flow; inadequate ventilation - ANSWER What are the
characteristics of shunting?
dead space is air inhaled with breathing, doesnt take part in gas exchange,
