Normal arterial pH is 7.35 to 7. 45. Both
metabolic and respiratory alkalosis have pH
more basic compare to the normal arterial
pH. The difference is 0.5 units. What is pH
value in alkalosis?
Niemann-Pick type C disease is a progressive
neurological disease; symptoms include
unsteady walking with uncoordinated limb
movements, slurred speech, a difficulty in
swallowing, epilepsy and tremor. This
condition is due to the abnormal functioning
of a lysosome. State the normal functions
performed by this organelle.
The pH of human blood is buffered at 7.35 to 7.45. If the [OH-] of the blood sample is 6.3x10-6, calculate its pH value. Is the patient’s pH within the range? Or is experiencing acidosis or alkalosis condition?
The normal pH of blood is 7.35-4.45. The normal pCO2 level is 35-45mmHg. John
has blood work performed. His recorded pH is 7.1. His recorded PCO2 is 20mmHg.
Based on this describe the acid base state of John. (ie, metabolic acidosis, metabolic
alkalosis, respiratory acidosis, and respiratory alkalosis). Support your answer.
