45) Determine PaCO2 level ✦ Provides information about res- piratory component of acid-base balance ✦ If abnormal, determine if low (< 35 mm Hg) or high (> 45 mm Hg) ✦ If abnormal, determine if it corresponds with change in pH (if pH is high, expect low PaCO2 [hypocapnia]; if pH is low, expect high PaCO2 [hypercapnia]) Check the pH level First, check the pH level. This figure forms the basis for understanding most other figures. 45). Then figure out whether the cause is respiratory or metabolic.
Add 2Љ to this figure to estimate the distance between the highest level of pulsation and the right atrium. A distance greater than 4Љ (10 cm) may indicate elevated CVP. 2Љ 2Љ Internal jugular vein External jugular vein Highest level of visible pulsation Angle of Louis Level of right atrium 45 degrees isn’t adequately replaced, the body’s cells can lose water, a condition called dehydration. CAUSES AND PATHOPHYSIOLOGY Loss of body fluids causes an increase in blood solute concentration (increased osmolality), and serum sodium levels rise.
These buffers rely on a series of chemical reactions in which pairs of weak acids and bases (such as carbonic acid and HCO3–) combine with stronger acids (such as hydrochloric acid) and bases to weaken them. Decreasing the strength of potentially damaging acids and bases reduces the danger those chemicals pose to pH balance. The kidneys assist HCO3– buffers by regulating HCO3– production. The lungs assist by regulating the carbonic acid production, which results from combining carbon dioxide (CO2) and water.
