Across
- 4. amount of base you need to add to. Solution to turn pH to normal once the effect of CO2 has been removed
- 6. levels higher than 6.5kPa lead to hyperventilation
- 8. a build up of excess base in the body
- 9. the type of scale used to calculate pH
- 11. how air is moved in and out of the lungs - too little is an early sign of respiratory acidosis
- 12. these can compensate for all four acid based imbalances - they can reabsorb virtually all bicarbonate and produce new bicarbonate. They take 12-24 hours to compensate for a respiratory acidosis or alkalosis
- 13. the active concentration of this is what pH measures
- 14. the primary chemical buffer in the body, the other two are phosphate and plasma protein.
Down
- 1. where the central chemoreceptors are located, which detect changes in the pH of CSF - overtime in conditions like COPD they maybe chronically desensitised
- 2. a protein which binds to hydrogen and acts as a chemical buffer for blood acidity
- 3. the clinical term for a pH less than 7.35
- 5. - there are three of these - it is an aqueous solution that can resist significant changes in pH levels upon the addition of small amount of acid or alkali.
- 7. which system other than urinary is involved in maintaining blood gas levels?
- 10. the process by which excess H+ is removed from the blood
