bicarb is a ________(kidney) hydrogen is a ___________(kidney) CO2 is a ___________(lung) |
base acid acid |
|
|
ph below 7.35 is ___________ ph above 7.45 is ___________ |
acidotic alkalotic |
|
|
compensation in the body when ph off kidneys: |
remove acid in urine retain or excrete bicarb slow to react |
|
|
compensation in the body when ph off lungs: |
one way to get rid of CO2-blow it off exhale RR low hypoventilation retain CO2 RR high hyperventilation eliminate CO2 quick to respond |
|
|
PaO2 |
80-100 |
|
|
PaCO2 |
35-45 |
|
|
HCO bicarb |
22-26 |
|
|
respiratory acidosis |
look for hypoventilation lung problem CO2 too much kidneys will compensate with bicarb and CO2 excrete acid retain bicarb low ph |
|
|
resp. acidosis causes |
retaining CO2 not exhaling mid abd incision narcotics sleeping pills pnemothorax collapsed lung |
|
|
resp acidosis s/s |
headache confusion sleepy could lead to coma hypoxic give oxygen early sign hypoxia=restless tachycardia |
|
|
resp acidosis tx |
fix breathing problem treat pnemonia get out secretions postural drainage percussion deep breathe cough sxn elevate hob incentive spirometry chest tubes with pnemothorax |
|
|
CO2 and ________ have inverse relationship |
O2 |
|
|
increase CO2=decrease in |
LOC & O2 |
|
|
resp alkaosis |
hyperventilating lungs are sick kidneys compensate kidneys excrete bicarb retain hydrogen CO2 problem losing CO2 increased ph |
|
|
resp alkalosis causes |
hyperventilation hysterical aspirin overdose-stimulating RR breathing too fast removing CO2 |
|
|
resp alkalosis s/s |
causes vasoconstriction of cerebral vessels=faint lighheaded peri-oral numb numb and tingling fingers and toes |
|
|
resp alkalosis tx |
dont wait on kidneys long time breathe into paper bag sedate to decrease RR treat cause monitor ABG's |
|
|
metabolic acidosis |
sick kidneys lungs compensate with CO2 retaining hydrogen not enough bicarb low ph RR increase to blow off acid |
|
|
metabolic acidosis causes |
DKA-Kussmaul RR starvation renal fail severe diarrhea |
|
|
metabolic acidosis s/s |
depend on cause hyperK-muscle twitching muscle weakness flaccid paralysis arrhythmias increased RR |
|
|
metabolic acidosis tx |
treat cause IV sodium bicarb not fix but give time |
|
|
metabolic alkalosis |
sick kidneys lungs compensate with CO2 bicarb too much excreting hydrogen increase ph |
|
|
metabolic alkalosis cause |
loss of upper gi contents vomiting ng sxn too many antacids too much sodium bicarb in code |
|
|
metabolic alkalosis s/s |
observe alt LOC muscle cramps life threatening arrhythmias hypoK |
|
|
metabolic alkalosis tx |
fix problem replace K |
