Which of the following is not the clinical features of severe COVID 19? ()
A: The high fever persists
B: Respiratory distress, RR≥30 times / min
C: Oxygen saturation≤93% at rest
D: Arterial partial pressure of oxygen (PaO2) / concentration of oxygen
(FiO2) ≤ 300mmHg
E: Lung imaging showed that the lesion progressed to > 50% within
24-48 hours

举一反三
- 6. Partial pressure of arterial blood oxygen refers to A: Oxygen partial pressure when oxygen saturation of hemoglobin is 50% B: Tension caused by oxygen molecules dissolved in arterial blood C: Hemoglobin and oxygen binding capacity D: The actual number of milliliters containing 02 in 100ml of blood E: Tension created by chemically bound oxygen in the blood
- Partial pressure of arterial blood oxygen refers to ( ) A: Tension caused by oxygen molecules dissolved in arterial blood B: Oxygen partial pressure when oxygen saturation of hemoglobin is 50% C: Hemoglobin and oxygen binding capacity D: The actual number of milliliters containing 02 in 100ml of blood E: Tension created by chemically bound oxygen in the blood
- The oxygen partial pressure or the amount of oxygen in arterial blood is called:
- 2. When isotonic hypoxemia occurs A: Reduced blood oxygen content B: Decreased partial pressure of arterial blood oxygen C: Decreased oxygen saturation of hemoglobin D: Normal blood oxygen content E: Tissue cell utilization oxygen disorder
- CO can cause a shift of the oxygen dissociation curve to left. At the apex of the lung, the arterial pressure is higher than alveolar pressure.
