- What type of conditions can cause Respiratory Acidosis?
- any condition that would keep Co2(an acid) in the lungs; hypoventilation, obstructive lung disease, oversedation
- Whay type of condition can cause Respiratory alkalosis?
- Conditions due to LACK of Co2 (either by loss or inability to intake);hypoxia, anxiety, pulm embolus, hyperventilation
- Salicylates, fever, gram neg septicemia, hepatic insufficiency, chf, asthma, severe anemia- all causes of?
- Respiratory Alkalosis
- Causes of Metabolic Alkalosis have what in common?
- they increase the bicarb or volume concentration of bicarb is high (too much bicarb), it causes pH level to rise making it alkalotic/losis
- Diabetic/starvation/alcoholicKetoacidosis, Poisoning, lactic acidosis, renal failure, and diarrhea are causes of?
- Metabolic Acidosis
- Drainage of pancreatic juice, ureterosigmoidoscopy, obstructed ileal loop, acetazolamide(diamox), ammonium chloride, renal tubular acidosis are causes of?
- Metabolic Acidosis
- The causes of Metabolic Acidosis have what in common?
- Volume concentration of bicarb is too low (not enough), it causes the pH level to fall making it acidosis/dotic
- Bicarb is a product of what body system?
- The kidneys
- Ventilatory failure occurs when the PaCO2 level reaches? Acute ventilatory failure is indicated by?
- >50; PaCO2 >50 AND pH <7.30
- SaO2 values give a measurement of ?
- the amount of oxygen bound to hgb compared to the total hgb.
- PaO2 measures?
- the partial pressure of oxygen dissolved in arterial plasma.
- Normal adult PaO2 is? and for an infant?
- 80-100; 40-70
- How is PaO2 for an elderly person calculated?
- Starting at 60 years, begin at 80mmHg, then for each year over 60, add 1mmHg
- At an age, a PaO2 lower than 40 is ?
- life-threatening and requires immediate action.
