|
|
|
Normal body fluid is slightly ____
|
alkaline
|
|
|
what is the normal PH in the body
|
7.35 to 7.45
|
|
|
If Ph gets below ___ or above __ we die

|
|
|
The best PH regulater is the ?
|
lungs
|
|
|
Kidneys help regulate the acid base balance thru the ____.
|
urine
|
|
|
If respiratory rates increase we blow out CO2 and this means we become more alkalinic
|
true
|
|
|
If we slow respiratory rates we in crease ____ in our body
|
acid
|
|
|
HCO3 is ____ and H2CO3 is ___
|
bicarbonate, carbonic acid
|
|
|
Sensors for CaO2 are found in the carotid arteies and the arortic arch
|
info
|
|
|
an adjustment of pH either throuh means of carbonic acid or bicarbonate
|
Compensation
|
|
|
An increase in HCO3 but not H2CO3 is
|
metabollic alkalosis
|
|
|
a decrease in HCO3 but not H2CO3
|
metabollic acidosis
|
|
|
a increase in H2CO3 but not HCO3
|
respiratory acidosis
|
|
|
a decrease in H2CO3 but not HCO3
|
respiratory alkalsosis
|
|
|
Depression evidenced by disorientatin up to coma
|
acidosis
|
|
|
this reults in overexcitability of the CNS, Muscles go into tetany up to convulsions
|
alkalosis
|
|
|
Low pH and Low HCO3, Depresses the CNS. S/S headache, confusion, drowsiness. May have: High respiratory rate, nausea/vomiting, peripheral dilation, warm, flushed skin.
|
metabolic acidosis
|
|
|
High pH and High HCO3, neuromuscular effects. S/S irritability/confusion, tingling of fingers and circumoral parethesia, carpopedal spasm, hypertonic muscles depressed. Decreased respiratory Rates
|
metabolic alkalosis
|
|
|
Low pH and High PaCO2, neuromuscular effects. S/S feeling of fullness in the head, mental cloudiness, palpitations, muscle twitching, convulsions, unconsciousness, warm flushed skin, ventricular fibrillation, decreased respirations.
|
respiratory acidosis
|
|
|
High pH and low PaCO2
s/s lightheadedness, inability to concentrate tinnitis, palpitations/ chest tight, sweating, dry mouth, hyperventilations, nausea/vomiting, blurred vision, convulsions and loss of consciousness, low co2 levels causes vasconstriction |
respiratory alkalosis
|
|
|
inadequate oxygenation of tissues
