High Altitude Physiology Flashcard Deck - 10 Cards

Flashcard 1: OSA, causes hypoventilation and resulting _____ hypoxia and hypercapnia

Answer: transient

Flashcard 2: In the _____, hypoxia causes vaso-constriction

Answer: lungs

Flashcard 3: Both peripheral and central chemoreceptors contribute to increased ventilation that occurs as a result of decreased _____.

Answer: pH

Extra: Both peripheral and central chemoreceptors respond to a decrease in pH (acidosis) and an increase in PCO2 (hypercapnia). - **Peripheral chemoreceptors** (carotid and aortic bodies): Respond directly to a decrease in **arterial pH**, an increase in PCO2, and a decrease in PO2 (< 60 mmHg). - **Central chemoreceptors** (medulla): Respond to a decrease in the **pH of the CSF/brain extracellular fluid**. Since H+ cannot cross the blood-brain barrier, this is primarily driven by an increase in arterial PCO2 (which crosses easily and is converted to H+ and HCO3-). Note: Only peripheral chemoreceptors respond to changes in arterial pH (e.g., metabolic acidosis) and low PO2. Both respond to changes in PCO2.

Flashcard 4: High altitude initially causes _____ alkalosis and hypoxia, which may cause acute altitude sickness

Answer: respiratory

Flashcard 5: In response to high altitude, there is chronic hypoxic pulmonary vasoconstriction which results in pulmonary _____ and RV hypertrophy

Answer: hypertension

Flashcard 6: Water fall effect has been used to describe the blood flow in the _____ portion of lung.

Answer: middle

Flashcard 7: The graph given below shows _ _thoracic obstruction

Answer: variable

Flashcard 8: The graph given depicts the _____ effect

Answer: Haldane

Flashcard 9: The alveolar gas equation states that the alveolar PO2 (PAO2) equals:

Answer: PAO2 = PIO2 – (PaCO2 / R) (PIO2 = FiO2 × [Patm – PH2O])

Extra: Where: - PAO2 = Alveolar PO2 - PIO2 = Inspired PO2 - PaCO2 = Arterial PCO2 - R = Respiratory Quotient (typically 0.8) At sea level: - Patm = 760 mmHg - PH2O = 47 mmHg

Flashcard 10: According to Fick's law, the rate of diffusion of a gas (Vgas) is equal to: _____
