Flashcards in Lecture 5 Arterial Blood Glass (missed this lecture) Deck (15):
Normal values according to FA (arterial blood):
33-44 mm Hg (CO2 = 40)
22-28 mm Hg (HCO3 = 25)
What does A-a gradient stand for? What is it normally (According to FA)
Alveolar PO2 - arterial PO2; 10-15 mm Hg
What does FIO2 stand for
fraction of inspired oxygen
Acute respiratory acidosis:
pH less than ____ and P CO2 more than ____. any kidney changes immediately?
chronic respiratory acidosis: the kidney compensates by increasing ____ absorption and increasing ___ excretion. thus, blood concentration of ____ increases
(never reaches normal)
Acute respiratory alkalosis:
pH greater than ____ and PCO2 less than _____. any kidney changes immediately?
Chronic respiratory alkalosis:
decreased _____ absorption and decreased ____ excretion; thus, blood concentration of ____ decreases
pH is less than _____. HCO3- concentration is (increased or decreased compared to 25)?; is there an immediate resp response?
7.35; decreased; yes, hyperventilation (kussamul)
chronic metabolic acidosis:
the body increases synthesis of ____. this allows an increased excretion of ___ as _____ acid
NH3; NH4+ titratable
pH is greater than ____. HCO3- is (greater or less than 25)?; any resp response?
7.45; greater than;
Equation for anion gap:
normal anion gap is ____
Na+ - (Cl + HCO3);
what metabolic disorder can high altitude cause (hypoxemia)? what about pulmonary embolism?
Airway obstruction and acute lung disease can cause what metabolic disorder?
predicted respiratory compensation for a single metabolic acidosis can be calculated using ____ formula. If the measured PCO2 differs significantly from the predicted, then a _____ disorder is likely present
