1. How to know if its respiratory acidosis or alkalosis: Look at pH
2. Causes of respiratory acidosis: COPD
Severe asthma
Pneumonia
Obesity hypoventilation syndrome
opioid use
GB syndrome
3. what is respiratory acoidosis: low pH
raised CO2
4. what is respiratory alkalosis: raised pH
low CO2
5. Causes of repsiratiory alkalosis: Hyperventilation - MOST COMMON
Fever
Mechanical ventilation
Aspirin overdose
Pulmonary embolism
Sepsis
CNS lesions
pain
pneumonthorax
6. What will respiratory acidosis with metabolic compensation look like...: -
Raised CO2 and raised HCO3-
- with a lower pH which will begin to increase due to compensation
7. What will respiratory alkalosis with metabolic compensation like like...: Re-
duced CO2 and reduced HCO3-
- with an increased pH that will begin to lower due to compensation
8. How long do compensatory mechanisms take to begin: resporatory : A couple
of hours after the intial acidosis/alkalosis

metabolic : takes a few days
9. What will a metabolic acidosis present as...: reduced HCO3- then if there is
compensation reduced CO2
- lower pH
10. Causes of metabolic acidosis: Diabetic ketoacidosis
Lactic acidosis
Kidney failure
Severe diarrhoea
Starvation
