NUR 2063 Pathophysiology ABG
- What is the normal pH of blood?
Answer
7.35-7.45
- What is an acidotic pH of blood?
Answer less than 7.35
- What is a basic pH of blood?
Answer more than 7.45
- What does it mean when one has a pH of blood less than 7.35?
Answer they are in acidosis
- What does it mean when one has a pH of blood greater than 7.45?
Answer they are in alkalosis
- Which 3 systems work together to maintain acid base balance?
Answer the buffers (blood), respiratory system and renal system
- Which 3 organs are vital to ABG levels?
Answer Blood, Kidneys and Lungs
- What is the normal range of PaCO2 in the blood?
Answer 1 / 2
35-45 mmHg
- Which system does PaCO2 target in the body?
Answer Respiratory
- What is an acidotic PaCO2 level?
Answer more than 45 mmHg
- What is alkalodic PaCO2 level?
Answer less than 35 mmHg
- What is the function of CO2 in the body, and why does it contribute to ABG values?
Answer It is an acid buffer, and it makes it so that the more CO2 the is in the body, the more acidic the PaCO2 level is in the body due to having more of it.
- What state is the body in when the PaCO2 is above 45 mmHg?
Answer Respiratory Acidosis
- What state is the body in when the PaCO2 is below 35 mmHg?
Answer Respiratory Alkalosis
- How do we know when there is an issue with the respiratory system when looking at ABG's
Answer The pH and the PaCO2 arrows will be in opposite directions, low pH, high CO2, or high pH and low CO2
- How do we know when there is an issue with the metabolic system when looking at
