Acid-base regulation Flashcards
Note the difference in values between the arterial side and the venous side
Define Alkalaemia, Acidaemia, Alkalosis and Acidosis?
Osis- are describing change or steady change
Aemia- are describing at any given point
The Pitts and Swan experiment
The blood has an ……………… buffering capacity that can react almost ………………….. to imbalances
The blood has an Enormous buffering capacity that can react almost immeadiattely to imbalances
explain the relationship between pH and hydrogen ion concentration
Name some metabolic acids?
Pyruvate and lactate
Henderson-Hasselbach equation: define and explain the Henderson-Hasselbach equation
Looka at lecture to do the tasks

What is base excess
Acid-base disturbance: explain the changes in blood gas measurements in acidosis (respiratory / metabolic), alkalosis (respiratory / metabolic) and respiratory failure (type 1 / type 2)
What are the basic guidlines for PaO2 in kPa
Changes in ventilation can stimulate a …………… compensatory response to change CO2 elimination and therefore alter pH
Changes in HCO3- and H+ retention/secretion in the kidneys can stimulate a ………….. compensatory response to increase/decrease pH
An acidosis will need an ……………. to correct
An alkalosis will need an …………….. to correct

List the 4 questions you ask when interpreting a blood gas and state the potential answers for these questions?
Report the following ABG results
Uncompensated Respiratory Alkalosis with moderate hypoxemia
Look at panopto if confused
Use this table to help with reporting
Look out for patterns in the table below- each highlighted bit has a pattern
Only compensated when flat
forget the dark one from your mind- you dont know which one did it- respiratory or metabolic
