Document Summary

Causes: hypoventilation, cns depression, pleural disease, lung disease, m/s disorder. Clinical presentation: decreased loc, muscle twitches, dysrhythmias, palpitations, flushed skin, elevated k+ Causes: catastrophic cns event, drugs, pregnancy, lung compliance, cirrhosis, pain/anxiety. Clinical presentation: headache, vertigo, paresthesias, tinnitus, electrolyte imbalance. Co2 greater than 45 is acidic co2 lower than 35 is basic. Causes: retaining too much h+, urine alkaline, anion gap acidosis (mulepak), non-anion gap acidosis (accrued: anion gap = na (cl + hco3) Clinical presentation: cns depression, cardiac dysrhythmias, electrolyte abnormalities. Causes: dehydration, hypokalemia, alkali ingestion, excess gluco or mineralocorticoids. Clinical presentation: diaphoresis, n/v, shallow breathing, increase neuromuscular excitability, ekg changes. Hco3 of less than 22 is acidic. Step 1 use ph to determine acidosis or alkalosis. Step 2 use paco2 to determine respiratory effect. Step 3 assume metabolic cause when respiratory is ruled out. If paco2 is abnormal and ph is normal, it indicates compensation ph>7. 4 would be compensated alkalosis ph<7. 4 would be compensated acidosis.
