  • Simple, reliable, affordable
  • On-screen step-by-step user guidance
  • For settings with few tests per day
The ABL9 blood gas analyser is specially designed for critical care environments running only a few tests per day.
 
It’s developed with ease of use in mind, fits in most settings due to its small footprint.
 
Using the on-screen step-by-step user guidance, you can easily measure patient samples on the ABL9 analyser and receive fast results on acid-base balance as well as oxygen and electrolyte status.
 
In a matter of seconds, you have the input you need to make the right diagnostic decisions for your critically ill patient.

Parameters measured

Blood gases: 
pH

Potential of hydrogen

The degree of acidity or alkalinity of any liquid (including blood) is a function of its hydrogen ion concentration [H+], and pH is simply a way of expressing hydrogen ion activity. The relationship between pH and hydrogen ion concentration is described thus:

pH = -log aH+
where aH+ is hydrogen ion activity.

Low pH is associated with acidosis and high pH with alkalosis [1,2].

, pCO2

Partial pressure of carbon dioxide

Carbon dioxide (CO2) is an acidic gas; the amount of CO2 in blood is largely controlled by the rate and depth of breathing or ventilation. pCO2 is the partial pressure of CO2 in blood. It is a measure of the pressure exerted by that small portion (~5 %) of total CO2 that remains in the gaseous state, dissolved in the blood plasma. pCO2 is the respiratory component of acid-base balance and reflects the adequacy of pulmonary ventilation. The severity of ventilator failure as well as the chronicity can be judged by the accompanying changes in acid-base status [1,2].

, pO2

Partial pressure of oxygen

The amount of oxygen in blood is controlled by many variables, e.g. ventilation/perfusion. pO2 is the partial pressure of oxygen in a gas phase in equilibrium with the blood. pO2 only reflects a small fraction (1 – 2 %) of total oxygen in blood that is dissolved in blood plasma [1]. The remaining 98 – 99 % of oxygen present in blood is bound to the hemoglobin in the erythrocytes. pO2 primarily reflects the oxygen uptake in the lungs. [2]

Hematocrit: 
Hct

Hematocrit

Hematocrit, the ratio between the volume of erythrocytes and the volume of whole blood. [1]

Electrolytes: 
cCa2+

Calcium

The calcium ion (Ca2+) is one of the most prevalent cations in the body, where approximately 1 % is present in the extracellular fluid of blood. Ca2+ plays a vital role for bone mineralization and many cellular processes, e.g. contractility of the heart and the skeletal musculature, neuromuscular transmission, hormone secretion and action in various enzymatic reactions such as, e.g. blood coagulation.

, cCl-

Chloride

Chloride (Cl-) is the major anion in the extracellular fluid and one of the most important anions in blood. The main function of Cl- is to maintain osmotic pressure, fluid balance, muscular activity, ionic neutrality in plasma, and help elucidate the cause of acid-base disturbances. [1]

, cK+

Potassium

Potassium (K+) is the major cation in the intracellular fluid, where it has a 25 - 37-fold higher concentration (∼150 mmol/L in tissue cells, ∼105 mmol/L in erythrocytes) than in the extracellular fluid (∼4 mmol/L) [1, 2]. K+ has several vital functions in the body, e.g. regulation of neuromuscular excitability, regulation of heart rhythm, regulation of intracellular and extracellular volume and acid-base status.

, cNa+

Sodium

Sodium (Na+) is the dominant cation in the extracellular fluid, where it has a 14-fold higher concentration (∼140 mmol/L) than in the intracellular fluid (∼10 mmol/L). Na+ is a major contributor of the osmolality of the extracellular fluid and its main function is largely in controlling and regulating water balance, and maintaining blood pressure. Na+ is also important for transmitting nerve impulses and activating muscle concretion. [1]

Metabolites: 
cLac

Lactate

Lactate, the anion that results from dissociation of lactic acid, is an intracellular metabolite of glucose. It is produced by skeletal muscle cells, red blood cells (erythrocytes), the brain, and other tissues during anaerobic energy production (glycolysis). Lactate is formed in the intracellular fluid from pyruvate; the reaction is catalyzed by the enzyme lactate dehydrogenase (LDH) [1,2].
