33 Questions
The reserve volume of the lungs is approximately 1.7 L.
True
Artificial Organs - Lung states a breathing volume at rest of 5.1 L/min.
False
The partial pressure of oxygen (O2) in the alveolus is higher than the O2-partial pressure in the capillary, according to Pulmonal Gas Exchange section.
True
The contact distance between alveolus and capillary plays a role in the Pulmonal Gas Exchange, according to the text.
True
Air contains approximately 21% carbon dioxide (CO2).
False
According to Henry's Law, the amount of gas dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid.
True
In Henry's Law, the solubility of a gas in a liquid decreases as the partial pressure of the gas above the liquid increases.
False
An increase in temperature generally decreases the solubility of gases in liquids, in accordance with Henry's Law.
True
Henry's Law applies only to ideal solutions and does not hold true for real-life scenarios.
False
Henry's Law is not applicable to the dissolution of noble gases in blood plasma.
False
According to Henry's Law, the amount of physically dissolved oxygen in the blood is directly proportional to the partial pressure of oxygen in the blood.
True
Physically dissolved CO2 in the blood can reach up to 10% of the total CO2 content.
False
The Haldane Effect states that the oxygen saturation in the blood is dependent on the concentration of CO2.
True
According to Henry's Law, as the partial pressure of CO2 in the blood increases, the amount of physically dissolved CO2 in the blood also increases.
True
The conversion of CO2 to hydrogen carbonate (HCO3-) in the blood occurs due to the action of carbonic anhydrase enzyme.
True
According to Henry's Law, the pressure of a gas in contact with a liquid is directly proportional to the concentration of the gas in the liquid.
True
According to Henry's Law, the solubility of a gas in a liquid decreases with an increase in temperature.
True
Henry's Law is not applicable to the exchange of gases in the alveoli of the lungs.
False
The Young-Laplace equation is used to calculate the pressure difference across alveoli walls.
True
Surfactant reduces the surface tension at the alveoli-air interface, in line with Henry's Law.
False
According to Henry's Law, the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of that gas above the liquid.
True
The Henry's constant for a specific gas-liquid system can vary with temperature.
True
According to Henry's Law, the solubility of a gas in a liquid will decrease as the partial pressure of the gas over the liquid increases.
False
The process of hyperbaric oxygenation (HBO) aligns with Henry's Law by increasing the partial pressure of oxygen to dissolve more oxygen in the blood.
True
In hyperbaric oxygenation (HBO), the decrease in gas bubble volume is unrelated to Henry's Law.
False
The history of film oxygenator mentions that it had independent pCO2 control.
False
Hollow fiber membrane with plasma sealing had a very large exchange area and high equipment costs, as per the text.
True
Foil membrane oxygenator had direct blood-air contact and large exchange surface.
False
The hollow fiber membrane with solid membrane mentioned in the text had low mass transfer resistance material.
False
Therapy for decompression illness caused by fast decompression after exposure to increased pressure includes hyperbaric oxygen therapy.
True
N2 bubble can cause pulmonary embolism, resulting in decreased oxygen transport and blood supply in the lung.
False
Mechanical ventilation does not aim to decrease the work of breathing (WOB) or improve the patient’s comfort.
False
Volume-limited ventilation (VC) is not affected by lung compliance.
False
Test your knowledge of mechanical ventilation, lung protective strategies, weaning, and extubation with this quiz. Questions cover topics such as low tidal volume ventilation, high PEEP, and spontaneous breathing trials.
