ABGS provide information about
|
- acid base status
- orgin of imbalance - impression of the ability of the body to regulate pH - reflection of the patient's P2 status |
|
|
Acid
|
A substance that release H+
|
|
|
Base
|
A substance that absorbs and accepts H+
|
|
|
pH
|
pH reflects the concentration of H+ ions
lower pH - more H+ ions - acidosis higher pH - more H+ ions - alkalosis |
|
|
PaCo2
|
Co2 within the blood
low - alkalosis high - acidosis |
|
|
HCO3 (bicarbonate)
|
- is a chemical (buffer) that keeps the pH of blood from becoming too acidic or too basic
low - acidosis high - alkalosis |
|
|
Causes of Metabolic acidosis
|
- Ketoacidosis (diabetic or starvation)
- Lactic Acidosis (imparied perfusion) - Renal failure - GIT - severe diarrhoea can lead to hyperventilation, tachycardia |
|
|
Causes of Metabolic alkalosis
|
- Diuretic therapy
- Vomiting can lead to hypoventilation, decreased blood flow, confusion |
|
|
Causes of Respiratory Alkalosis
|
- anxiety, pain, fear, stress
- hypoxaemia - head injury - sepsis - pulmonary issues ie pneumonia, asthma |
|
|
Causes of Respiratory acidosis
|
- Type II resp failure COPD, asthma attack, pulmonary oedema
