What is paco2 ABGs

What is paco2 ABGs,s Partial pressure of carbon dioxide (Poor) is the measure of carbon dioxide within arterial or versus blood. It is one of the several measures calculated (ABG) Best arterial blood gases, often performed by people with Lung diseases, neuromuscular diseases, and other illnesses PaCo₂ specifically evaluates Carbon dioxide (CO2) levels in the blood.

Partial pressure means the pressure of a single gas component in a mixture of gases. The partial pressure of carbon dioxide reveals the amount of carbon dioxide gas dissolved in the blood. Paco also reflects this exchange from the Lungs to the outer air. It evaluates the respiratory. abnormality and to determine the acidity or alkalinity of the blood.

Purpose of Test:

PaCo₂ is used for getting a glimpse of the body’s metabolic and respiratory state and it helps evaluate lung function and the effectiveness of oxygen therapy and can determine the body’s pH or acid-base balance changes if PaCo₂ pressure is an accumulation of too much carbon dioxide in the blood. Having too much Co₂ is called Hypercapnia, which is a condition common in people with last-stage chronic obstructive pulmonary disease (COPD).

Causes Of High (PCO₂):

• Disease Causing stiffening of the chest cage.
• Neuromuscular weakness.
• Obesity hypoventilation
• Hypothermia
• Severe obstruction of the airway
• Emphysema
• Anesthesia
• Trauma to heads
• Hypothyroidism
• Chronic Bronchitis
• Severe vomiting

Causes OF Low (Paco₂, PCo₂):

• Pulmonary Embolism
• Anxiety
• Hypoxia
• Pregnancy’s
• Hyperventilation
• Kidney failure
• Severe Diarrhea
• Starvation
• Diabetic Acidosis

Terms used for High and Low in Blood (PCO₂):

Hypercapnia or Hypercarbia:

when the lungs hold CO₂, the level of Co₂ in the blood increases and that Condition is known as hypercapnia or Hypercarbia, which is an acidic state.

Hypocapnia or Hypocarbia:

When the lungs expire more Co₂ than normal, the level of CO₂ in the blood decreases, and that condition is called Hypocapnia or Hypocarbia. Which is an Alkalotic state.

Normal Range OF (PCO₂):

• (PaCo₂) Partial pressure of Carbon Dioxide 35 to 45 mmHg (In Arterial Blood).
• (Pa Cor) Partial pressure of Co₂ 41 to 51 mmHg (In venous Blood).

How to perform the test:

A Blood Sample is Needed.

Procedure:

• There is no special preparation. If you are on Oxygen therapy, the oxygen concentration must remain constant for 20 minutes before the test.
• If you are taking any blood-thinning medicines (anticoagulants), including Aspirin, warfarin, etc.
• Collect the 2ml arterial blood or Venous blood in a heparinized syringe, or Green top Tube with sodium heparin or lithium Heparin.
• Mix the sample immediately Stability of the Sample at room temperature is 30 minutes.
• The stability of is crushed ice container is 1 hour.

Interpreting Results:

The normal range of partial pressure of Co₂ is between 35 and 45 mmHg the value is higher than 45 mmHg. It indicates that too much CO₂ in your body of a value under 35mmHg and you have too little.
