What is PO2 in blood?
PO2 in blood is the amount of gases in your blood. In medical terms, this is commonly called the Alveolar-arterial.
Is pao2 and po2 the same?
Yes, PaO2 (partial pressure of oxygen in arterial blood) and pO2 (partial pressure of oxygen) are the same. PaO2 specifically refers to the measurement of oxygen in arterial blood, while pO2 is a more general term referring to the partial pressure of oxygen in any context.
What is hypoxic threshold?
Hypoxic threshold is the point at which oxygen delivery to tissues becomes insufficient to meet their metabolic demands, resulting in a decrease in tissue oxygen saturation. This can lead to negative effects on physical performance and cognitive function. Athletes often train to improve their hypoxic threshold to enhance endurance and overall performance.
Explain the way anatomical shunt through the bronchial circulation causes an PO2 difference between alveolar gas and arterial blood.?

What is physiological shunt?
Is a mixtures of oxygenated blood with some deoxygenated blood. It results in reduction of arterial PO2 by 2mmHg and reduction of arterial oxygen saturation by 0.5% compared to oxygenated blood coming from alveolar capillaries
What color is normal systemic arterial blood?
Bright cherry red is the normal systemic arterial blood color
Arterial PO2 levels?
If 2.2 liters of gas is inhaled at 18 degrees Celsius and is heated to 38 degrees Celsius in the lungs, what is the new volume of the gas
How does exercise affect pO2 in the muscle cell?
Arterial po2 will not change because it's almost at maximum already. Venous po2 will decrease due to increased oxygen consumption by respiring muscle. Venous and arterial pCo2 will actually either stay the same or fall due to the increased ventilation stimulated by the increased Co2 production by respiring muscles. The increased pCO2 is detected by central and peripheral chemoreceptors and leads to increased ventilation, resulting in increased ventilation - causing pCo2 to remain normal or decrease. This mechanism cannot be used to explain the ventilation increase in light exercise because pCo2 hardly rises at all during light exercise, therefore the chemoreceptors may not be responsible for the mechanism resulting in increased ventilation,
What is the difference between PO2 and Sp02?
PO2 refers to the partial pressure of oxygen in the blood, typically measured via arterial blood gas analysis. SpO2, on the other hand, represents the oxygen saturation level in the blood, measured non-invasively through pulse oximetry. In simpler terms, PO2 shows how much oxygen is dissolved in the blood, while SpO2 indicates the percentage of hemoglobin carrying oxygen.
What is the normal ph range for arterial blood?
Normal PH for arterial blood is 7.4 and it is basic ph below 7 is acidic and 7 to 7.3 is neutral
What is the normal value of arterial blood gas?
1. PH, HCO3, and base excess, depicts the acid-base balance of the body, which is being controlled by the kidneys and lungs. 2. PCO2 gives the ventilatory status of the body 3 PO2 tells the oxygenation status of the body.
What is normal arterial pCO2 in kPa?
5.3 kPa
