oxygenation (final) Flashcards
respiratory acidosis
lungs retain CO2
ph < 7.35 PaCO2 > 45
respiratory acidosis causes
HYPOVENTILATION
pneumonia
copd
trauma
asthma attack
overdose
alcohol intoxication
post op
sleep apnea
respiratory acidosis s/s
decreased RR
restlessness
confusion
tremors
sleepy
cyanosis
dizziness
respiratory acidosis interventions
O2
semi fowlers
increase fluids
medications
resp. Tx
respiratory alkalosis
lungs lose CO2, not enough
pH >7.35 PaCO2 <35
respiratory alkalosis causes
HYPERVENTILATION
increased temp
aspirin toxicity
anxiety (panic attack)
pain
respiratory alkalosis s/s
chvosteks sign (facial twitching)
increased HR
confusion LOC
tremors (finger cramps)
respiratory alkalosis interventions
**rebreathe in paper bag
anxiety meds to decrease RR
fix breathing problem
calcium gluconate
metabolic acidosis
too little base (Alk)
metabolic acidosis causes
‘assidosis’ — DIARRHEA
renal failure
starvation
DKA
metabolic acidosis s/s
decreased BP
fruity breath
lethargy
kussmal respirations
increased K, dysrhythmias
N/V
metabolic acidosis interventions
assess LOC
I+O’s
seizure precautions
metabolic alkalosis
too much base; loss of acid
metabolic alkalosis causes
‘elkalosis’ — vomitting
NGT suctioning
metabolic alkalosis s/s
decreased Ca and K
muscle cramps, dysrhythmias
seizures
tingling, numbness
metabolic alkalosis interventions
monitor Ca and K
seizure precautions
diuretics
early symptoms of hypoxia
R estlessness
A nxiety
T achycardia
late symptoms of hypoxia
B radycardia
E xtreme restlessness
D yspnea
PEDS symptoms of hypoxia
F eeding difficulty
I nspiratory stridor
N ares flares
E xpiratory grunt
S ternal retractions
6 P’s of dyspnea
possible foreign body
pulmonary embolus (clot)
pneumonia
pump failure
pneumothorax
pulmonary bronchial constriction
pneumothorax
air outside of the lung but in the pleural cavity
kussmals respirations
rapid and deep breathing
fruity acetone breath
diabetes
cheyne stokes respirations
‘death rattle’
(one breath, rapid, no breath)
biots respirations
irregular
tachypnea
fast breathing
bradypnea
slow breathing
rhonchi
cough changes the sound
due to mucus
ex: COPD
crackles
fluid base of lungs
ex: pneumonia
wheezing
closed airway
ex: asthma
when is hematocrit increased?
chronic hypoxia
chronic bronchitis main issue
inflammation of bronchioles and excessive mucus production
V/Q mismatch found in
chronic bronchitis
decreased ventilation
increased perfusion
chronic bronchitis known as
‘blue bloaters’
cyanosis
increased lung volume
eventual edema
chronic bronchitis s/s
chronic productive cough
SOB
edema
cyanosis
emphysema main issue
damage to alveolar sacs (lose elasticity)
“air trapping”
matched V/Q found in
emphysema
decreased ventilation
decreased perfusion
emphysema known as
“pink puffers”
barrel chest
hyperventilation
emphysema s/s
SOB
hyperventilation
weight loss
barrel chest
