What is the difference between ventilation and respiration? - CORRECT
ANSWER-Ventilation is the movement of air in and out of the lungs,
while respiration is the exchange of oxygen and carbon dioxide
between an organism and its environment.
What is external respiration? - CORRECT ANSWER-The diffusion of
oxygen and carbon dioxide in and out of the alveolar capillaries.
What is internal respiration? - CORRECT ANSWER-The exchange of
oxygen and carbon dioxide between the systemic capillaries and the
cells of the body.
What happens during quiet expiration? - CORRECT ANSWER-The
pressure in the potential and visceral pleura changes, with intrapleural
pressure being approximately -5 cm H2O at the end of exhalation.
, What is intrapleural pressure (Ppl)? - CORRECT ANSWER-The pressure
within the pleural cavity, which is estimated based on the pressure
changes during breathing.
What is the primary purpose of ventilation? - CORRECT ANSWER-To
move air in and out of the lungs and remove carbon dioxide.
What are the three basic physiologic objectives of mechanical
ventilation? - CORRECT ANSWER-1. Oxygenation - delivering oxygen
into the blood; 2. Ventilation - removing carbon dioxide; 3. Acid-base
balance - maintaining normal pH.
What are eight clinical objectives of mechanical ventilation? - CORRECT
ANSWER-1. Reverse acute respiratory failure; 2. Reverse respiratory
distress; 3. Reverse hypoxemia; 4. Reverse atelectasis; 5. Reverse
muscle fatigue; 6. Permit sedation or paralysis; 7. Reduce oxygen
consumption; 8. Reduce complications and mortality.
What are ten physical signs of respiratory distress? - CORRECT
ANSWER-1. Tachypnea; 2. Accessory muscle use; 3. Nasal flaring; 4.
Cyanosis; 5. Tachycardia; 6. Intercostal retractions; 7. Diaphoresis; 8.
Restlessness or anxiety; 9. Paradoxical breathing; 10. Abnormal breath
sounds.
