Understanding Arterial Blood Gas Test

An Arterial Blood Gas Test is a more comprehensive blood test (also known as an ABG test) that measures the acidity and level of oxygen and carbon dioxide specifically in the blood from an artery. During this test, the following will be checked and measured.

  • The pressure of oxygen dissolved in the human blood and how smooth the oxygen can move from the airspace of the lungs into the blood.
  • The pressure of carbon dioxide dissolved in the blood and how well carbon dioxide can move out of the human body.
  • The acidity (pH) or amount of hydrogen ions (H+) in the blood.
  • The amount of bicarbonate in the blood.
  • The amount of oxygen in the blood.
  • The amount of hemoglobin in the red blood cells carrying oxygen.

What Is An Arterial Blood Gas Test For?

Such test is usually done to check for patients with severe breathing problems and lung diseases i.e. asthma or chronic obstructive pulmonary disease (COPD), check if patients are getting the right amount of oxygen or if extra oxygen is needed in the hospital, check if treatment for lung diseases is effective, as well as measure the acid-base level in the blood of patients with heart or kidney failure, uncontrolled diabetes, severe infections or sleeping disorders.

Before going for an arterial blood gas test, make sure that you talk to your health care provider about any concern you have i.e. the risks involved, how will it be done, and what does the result mean.

Causes And Symptoms Of Poor Blood Circulation

Do you suffer from poor blood circulation? If you do, we would strongly recommend that you should visit your health care provider immediately to seek medical advice. However, if you do not know what is poor blood circulation, you may like to read more in this article.

What Are The Causes?

Poor blood circulation is an outcome of several factors i.e. imbalanced diet and lack of exercise as well as certain lifestyle choices we made which are detrimental to our health. It does not take a day to happen hence poor blood circulation is usually a result of aging since it affect the elders more.

How Does Poor Blood Circulation Happen?

Due to imbalanced diet and lack of exercise, plagues (fatty deposits when hardened) are formed on the blood arterial walls. As a result, the blood passage to and from the heart becomes obstructed and the blood are not circulated well.

What Are The Symptoms?

When a person suffers from poor blood circulation, below are a list of symptoms which might be observed. You may have some or in worse case, all the symptoms depending on your health condition.

  • Loss of memory, lack of mental clarity, feeling lethargic, unexplained headaches and sudden dizziness.
  • Chest pain, shortness of breathe, altered heart rate, feeling tired easily and all the time.
  • Sudden numbness of hands, feet and fingers or painful leg cramps. Lack of appetite, sudden loss of weight or luster-less skin.
  • Lack of sex drive or fatigue. Lack of vitality and energy.

Understanding causes and symptoms of poor blood circulation now is essential to prevent serious blood circulation problems in future.

Understanding Blood Circulation

Blood circulation is also known as human circulatory system. The key components of a human circulatory system is the heart, the blood and the blood vessels.

Understanding What Is Circulatory System

It is an organ system that is collectively made up of the cardiovascular and lymphatic systems. The cardiovascular system is formed by the heart, blood and blood vessels whereas the lymphatic system is formed by the lymph, lymph nodes, and lymph vessels. Blood and lymph fluids move through the circulatory system. The human digestive system works with the circulatory system to provide nutrients to its needs to keep the heart pumping.

Understanding What Is Blood Circulation

Human blood circulation comprises mainly 2 forms of circulations, the pulmonary and systemic circulations. During pulmonary circulation, the human blood is oxygenated after a loop through the lung. As for systemic circulation, the blood is circulated (loop) through the rest of the body to provide oxygenated blood.

Blood circulation helps to move nutrients, gases or even waste, to and from cells. This would then help in fighting diseases and stabilizing blood temperature and pH to maintain homeostasis.
