◉ normal PH.
Answer: 7.35-7.45
◉ PH is the.
Answer: concentration of hydrogen ions in arterial blood
◉ hydrogen ions increase the __________ of Arterial blood.
Answer: acidity
◉ fatal PH ranges.
Answer: greater than 7.8 or less than 6.8
◉ PaO2.
Answer: partial pressure of oxygen, how much is available to bind to
hydrogen
normally 80-100
◉ SaO2.
,Answer: Oxygen saturation, percentage of oxygen bound to
hemoglobin above 92 or 94 goes to 100
◉ PaCO2.
Answer: partial pressure of carbon dioxide, is acidic, adjusted by
changes in rate and depth of respirations
35-45 is normal
you release more CO2 when breathing quickly, making it more basic
◉ HCO2.
Answer: bicarbonate is a base
metabolic issue
normal 22-26
◉ respiratory acidosis values.
Answer: PaCO2 increased PH decreased
◉ respiratory alkalosis values.
Answer: PACO2 decreased PH increased
◉ PH regulation controlled by three systems.
Answer: 1. chemical buffer system
, 2. respiratory system
3. renal system
◉ metabolic acidosis values.
Answer: HCO3 (bicarb) low PH low
◉ metabolic alkalosis value.
Answer: HCO3 (bicarb) high PH high
◉ respiratory changes when body detects acidity 5-15 minutes.
Answer: you will breath faster getting rid of CO2 to get rid of the
acid and vice versa with basic. creates carbonic acid by combining
CO2 w water
◉ renal system changes when acidity is detected in 24 hrs.
Answer: holding on to bicarb and start neutralizing or vice versa will
excrete bicarb to get rid of its basisity
◉ hypoxemia.
Answer: PaO2
80-100 normal
60-80 mild
