You perform an ABG, which reveals the following results: • PaO2: 52.5 mmHg • pH: 7.29 • PaCO2: 68 mmHg • HCO3–: 26 What does the ABG show: Oxygenation (PaO2): pH: PaCO2: HCO3–: Interpretation: What symptoms or signs are associated with hypercapnia (↑CO2)?A patient has severe uncompensated respiratory acidosis. Temperature is normal and hemoglobin concentration is within the reference range. Which of the following oxygen dissociation curves best describes the relationship between oxygen content and PO2 (the solid curve is normal) in this patient?A 50-year-old man came to the emergency department after returning from foreign travel.

Explain why ventilation is reduced in the patient.Breathing in too much carbon monoxide will most likely result in the production of whatWhich of the following statements is true for Bohr effect: a. Bohr effect describes carbon monoxide poisoning. b. Bohr effect prevents oxygen binding to hemoglobin. c. Bohr effect allows effective oxygen discharge in tissues due to higher acidity (decreased pH) than in lungs. d. Bohr effect allows effective oxygen discharge in tissues due to lower acidity (increased pH) than in lungs.
