What nursing interventions are important to implement when assisting with an ABG?

Nursing Interventions & Considerations Report such changes as well as any variations in ABG values or electrolyte status immediately. Maintain adequate hydration. Maintain patent airway and provide humidification if acidosis requires mechanical ventilation.

How do nurses do ABGs?

Steps in ABG analysis using the tic-tac-toe method

  1. Memorize the normal values.
  2. Create your tic-tac-toe grid.
  3. Determine if pH is under NORMAL, ACIDOSIS, or ALKALOSIS.
  4. Determine if PaCO2 is under NORMAL, ACIDOSIS, or ALKALOSIS.
  5. Determine if HCO3 is under NORMAL, ACIDOSIS, or ALKALOSIS.

Can a nurse perform an ABG?

The key skill required is arterial blood gas sampling. This has traditionally been the role of the doctor, however by using an education and training package along with a competency-based assessment, nurses can now perform this extended role.

What is the importance of ABG analysis and interpretation in patient care?

An ABG is one of the most commonly used tests to measure oxygenation and blood acid levels, two important measures of a patient’s clinical status and correct interpretation can lead to quicker and more accurate changes in the plan of care.

What are the special nursing responsibilities during administration of oxygen?

Nurses have a responsibility to ensure that oxygenation is optimised at pulmonary and cellular level as part of their duty of care to patients. This requires knowledge of respiratory and cardiac physiology, as well as selection of the appropriate equipment and delivery method for supplemental oxygen therapy.

What are the nursing responsibilities in monitoring fluid and electrolyte balance?

The nurse must be alert for central nervous system changes such as lethargy, seizures, confusion, and muscle twitching. Diet. The nurse must encourage intake of electrolytes that are deficient or restrict intake if the electrolyte levels are excessive.

How do you do ABG analysis?

For an arterial blood gas test, a respiratory therapist will take a sample of blood from one of your arteries. This is because there are higher oxygen levels in blood from an artery than blood from a vein. A respiratory therapist usually takes the sample from an artery inside your wrist known as the radial artery.

How often should ABG be repeated?

Intermittent arterial blood gas analyses must be performed more frequently, up to every 10 minutes, to detect changes of 20% in arterial partial pressure of oxygen.

Who is allowed to draw ABGs?

Most ABG samples can be drawn by a respiratory technician or specially trained nurse. Collection from the femoral artery, however, is usually performed by a doctor. Before attempting a radial puncture, you should perform Allen’s test. (See Performing Allen’s test, page 36.)

What is the purpose of ABG test?

An arterial blood gas (ABG) test is a blood test that requires a sample from an artery in your body to measure the levels of oxygen and carbon dioxide in your blood. The test also checks the balance of acids and bases, known as the pH balance, in your blood.

What is the importance of blood gas analysis?

The blood gas test can determine how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood. Imbalances in the oxygen, carbon dioxide, and pH levels of your blood can indicate the presence of certain medical conditions.
