Acid-Base - PowerPoint/1 Flashcards
systemic increase in H+ concentration or decrease in bicarbonate
acidosis
pH < 7.35 and CO2 >40
respiratory acidosis
loss of gastric juices is to
metabolic alkalosis
what is increased in acidosis
potassium levels
metabolic alkalosis
elevation of HCO- usually caused by an excessive loss of metabolic acids
respiratory acidosis
elevation of pCO2 as a result of ventilation depression
normal arterial blood pH value
7.35-7.45
initial stages of pulmonary emboli is to
respiratory alkalosis
respiratory alkalosis
depression of pCO2 as a result of alveolar hyperventilation
elevation of pCO2 as a result of ventilation depression
respiratory acidosis
acid-base balance is carefully regulated to
maintain a normal pH via multiple mechanisms
what have negative charges, and can serve as buffers for H+
protein (hgb)
protein buffering aka
hemoglobin
renal buffering
secretion of H+ in urine and reabsorption of HCO-
ABG readings pH CO2 HCO O2
- pH 7.35-7.45
- CO2 36-44
- HCO 22-26
- O2 >70
respiratory acidosis
pH and CO2
pH <7.35
CO2 >40
metabolic acidosis
pH and CO2
pH <7.35
CO2 <40
elevation of HCO- usually caused by an excessive loss of metabolic acids
metabolic alkalosis
acidosis
systemic increase in H+ concentration or decrease in bicarbonate
hyperkalemia is to
metabolic acidosis
arterial blood pH is obtained by
ABG sampling
overuse of antacids is to
metabolic alkalosis
systemic decrease in H+ concentration or increase in bicarbonate
alkalosis
respiratory alkalosis causes include
- initial stages of pulmonary emboli
- hypoxia
- fever
- pregnancy
- anxiety
- high altitudes
depression of pCO2 as a result of alveolar hyperventilation
respiratory alkalosis
metabolic alkalosis
pH and CO2
pH >7.45
CO2 >40
pregnancy is to
respiratory alkalosis
pulmonary edema is to
respiraotyr acidosis
potassium levels go up in
acidosis
sepsis is to
metabolic acidosis
potassium wasting diuretics is to
metabolic alkalosis
respiratory alkalosis
pH and CO2
pH >7.45
CO2 <40
carefully regulated to maintain a normal pH via multiple mechanisms
acid-base balance
secretion of H+ in urine and reabsorption of HCO- is to what buffering system
renal
anxiety is to
respiratory alkalosis
pH > 7.45 and CO2 > 40
metabolic alkalosis
fever is to
respiratory alkalosis
respiratory acidosis causes include
7
- hypoventilation
- drug overdose
- pulmonary edema
- chest trauma
- neuromuscular disease
- airway obstruction
- COPD
COPD is to
respiratory acidosis
protein buffering (Hgb)
proteins have negative charges, so they can serve as buffers for H+
pH > 7.45 and CO2 <40
respiratory alkalosis
severe diarrhea is to
metabolic acidosis
alkalosis
systemic decrease in H+ concentration or increase in bicarbonate
metabolic acidosis
depression of HCO- or an increase in noncarbonic acids
high altitudes is to
respiratory alkalosis
pH < 7.35 and CO2 < 40
metabolic acidosis
DKA is to
metabolic acidosis
depression of HCO- or an increase in noncarbonic acids
metabolic acidosis
acidic with a low concentration of CO2
metabolic acidosis
metabolic alkalosis causes include
3
- antacid over use
- potassium wasting diuretics
- loss of gastric juices
metabolic acidosis breathing
compensatory kussmal breathing
acidic with a high concentration of CO2
respiratory acidosis i.e. hypoventilation
shock is to
metabolic acidosis
hypoxia is to
respiratory alkalosis
metabolic acidosis causes include
6
- salicylate OB (aspirin)
- severe diarrhea
- renal failure
- shock
- sepsis
- DKA
