Acid-Base balance Flashcards
The expected blood gas results for a patient in chronic renal failure would match the pattern of?
metabolic acidosis
severe diarrhea causes
metabolic acidosis
what is metabolic acidosis
a condition in which too much acid accumulates in the body
causes- buildup of body toxins, kidney failure, ingestion of certain drugs or toxins. rare complication to diabetes
Factors that contribute to a PCO2 electrode requiring 60-120 seconds to reach equilibrium include
diffusion characteristics of the membrane
an emphysema patient suffering from fluid accumulation in the alveolar spaces is likely to be in what metabolic state?
respiratory acidosis
What is emphysema?
A condition in which the air sacs of the lungs are damaged and enlarged causing breathlesesness
define alveoli
tiny air save at the end of the bronchioles. Where the lungs and blood exchange oxygen and carbon dioxide during the process of breathing in/out
At blood pH 7.4, what is the ratio of bicarbonate to carbonic acid?
20:1 (normal ratio)
The reference range for the pH of arterial blood measured at 37degress celsius is
7.35-7.45
A 68 yr old man arrives in the er with a glucose level of 722mg/dL and serum acetone of 4+ undiluted. An arterial blood gas from this patient is likely to be:
low pH
A patient is admitted to the emergency room in a state of metabolic alkalosis. What would be consistent with this diagnosis?
high TCO2, increased HCO3
A person suspected of having metabolic alkalosis would have what lab results?
CO2 content and pH elevated
Metabolic acidosis is described as a(n)?
decrease in CO2 content and PCO2 with a decreased pH
Respiratory acidosis is described as
increase in CO2 content and PCO2 with a decreased pH
A common cause of respiartory alkalosis is:
hyperventalation
