What is acid-base balance
|
changes in they hydrogen ion concentration or the ph of the blood
|
|
|
PH
|
measures the conconcentration of hydrogen ions
inversely related to H+ ion so lower ph = more H+ ion = acidic, higher the ph less H+ = alkalotics |
|
|
acid
|
formed as an end product of metabolism of proteins, cars and fats, can release H+ ions most are weak in the body ie: carbonic in the lungs
|
|
|
Bases
|
substances that accepts H+ ions ie: bicarbonate elminiated, maintained and created in kidneys
|
|
|
3 regulators of acid/base
|
Chemical buffers in ICF & EC react seconds to minutes
main one being protein (albumin) Respirator system reacts within minutes Renal system within hours to days |
|
|
Arterial blood ranges
|
PH 7.35 - 7.45
PaCO2 35 - 45 Bicarbonate HCO3 22 - 26 PaO2 80 - 100 SaO2 95- 100 |
|
|
nursing care for respiratory acidosis
|
maintain patent airway & optimize gas exchange
pulmonary hygiene purse lip brathing, fowlers or semifowlers turn cough deep breath ventilatory support used when patient cant maintain an 02 sat of 90% monitor VS safety side rails up x2, padded side rails, possible restraints drugs = mucolytic agents, expectorants |
|
|
dark skin and pulse ox
|
may appear falsely elevated
|
|
|
nursing care for respiratory alkalosis
|
correct underlying cause
improve oxygenation rapidly sedation, anti-anxiety agents breathing in a paper bag relaxation techniques, rest periods, safety measures |
|
|
ABGs purpose
|
to diagnose acid-base imbalances and to monitor the patients response to treatment wait 20 to 30 minutes after suctioning or a respiratory tx
|
|
|
how to interpret ABGs
|
check ph
what is the Co2 what is the bicarb level is it compensated what is the PaO2 and SaO3 |
