The speed and time of the centrifuge directly affect the microhematocrit values. Errors can be caused if it is not spun at the correct speed.

The "normal" PCV count for males is 48% and 38% for women. The count does not vary for changes in body mass.

The normal values for Areterial blood gas (for adults!) are as follows;Pao2 >> 12-15kPa (90-110mmHg)Paco2 >> 4.5-6.1kPa (34-46mmHg)Bicarbonate >> 21-27.5mmol/lH+ ions >> 36-44mmol/l (7.35-7.45 pH units)I also referred to the Baillière's Nurses Dictionary to check!
Values outside of the normal range always indicates the presence of disease?
Reference ranges vary from laboratory to laboratory and depend upon the method used. For adults, normal values are usually found within the following ranges (1 mg = approximately 0.000035 oz. and 1 dL = approximately 0.33 oz.):.
For adults it is only 12 breaths per minute when relaxed. Other older textbooks often say even smaller values (e.g., 8-10 breaths per minute). Most modern adults breathe much faster at about 15-20 breaths per minute
After the adults left, the girls acted normal again because they were pretending to be in a coma when the adults were there.
