His blood pressure is 100/ 80mmHg, pulse is 110 per minute, respiratory rate is 28 per minute, temperature is 38. 2℃. The patient is mildly cyanotic. The following arterial blood gases were obtained on room air: CaO2max =20ml/dL, CaO2 = 15ml/dL, PaO2，= 50mmHg, C(a-v)O2 = 4ml/dL. Questions : 1.What is the most appropriate type of hypoxia for this patient? 2. What are the common causes of this type hypoxia? 3. What are the characteristic alterations of blood O2 in this type hypoxia? 4. What is the colour of skin and mucous membranes in this type
