Document Summary

Altered homeostasis associated with illness or injury (v/s drops/increased outside of normal ranges, has to be at least one unstable v/s to be defined as unstable) Early recognition and intervention can save an unstable patient"s life. Numerous conditions lead to acid-base imbalances (copd, hf, diabetes, renal and liver failure) ph is the measurement of h+ ion concentration arterial blood normally has slightly alkaline ph. Normal value in the body = 7. 35 7. 45. Total neutral blood arterial ph = 7. 40 ph is measures by drawing an abg. Venous blood has a normal ph between 7. 31 7. 41. Carbonic acid-bicarbonate buffer system (most important buffer, works the fastest. ***cannot maintain ph w/o adequate resp and renal; so cannot work by itself*** Acid/base imbalance occurs with retained co2 (high) or blown off (low) co2. Responds within hours to days of imbalance, unless renal system is the cause of disease.
