What is anemia?
Anemia is a blood disorder in which the ability of the blood to carry oxygen is reduced due to a lower than normal number of red blood cells or a reduced amount of hemoglobin. When anemia is slow to start, symptoms are often vague, such as fatigue, weakness, shortness of breath, headaches, and decreased exercise capacity When anemia is severe, symptoms may include confusion, feeling faint, loss of consciousness, and thirst Must be visibly pale to be severely anemic Depending on the underlying cause, other symptoms may occur Pre-operative anemia increases the risk of needing a blood transfusion after surgery Anemia may be temporary or chronic It can range from mild to severe.
What is anemic hypoxia?
Anemic hypoxia is a blood defect that occurs when the blood's ability to carry oxygen decreases. Causes include altitude sickness, carbon monoxide poisoning, different types of anemia, bleeding, and jumping electrodes.
One of the main functions of the cardiopulmonary system is to make sure that all parts of your body are receiving oxygen. Hypoxia is a biological condition in which tissues are deprived of oxygen.
Anemic hypoxia occurs when the ability of the blood to carry oxygen decreases. This blood defect means that there is less oxygen in the blood, thus, it becomes oxygen-poor. Hence, oxygen deprivation is expected to lead to a loss of blood oxygen to the blood. The oxygen concentration in the blood is known as the blood oxygen flux. Therefore, the blood oxygen concentration, which is the oxygen concentration in the blood respectable is the blood than expected from the total number of hemoglobin in the blood. For the cases where the blood defect was present, the mean oxygen in the blood was smaller than expected. As the hemoglobin concentration in the blood decreased, the mean oxygen in the blood decreased with respectably molecules (or oxygen-binding sites) in the blood available to bind oxygen.
What are the symptoms of anemic hypoxia?
Symptoms of anemic hypoxia may vary from person to person, as well as the length of time that the symptoms are present. They include:
- Blue lips
- Confusion
- Dizziness
- Fainting
- Headaches
- High blood pressure
- Lack of coordination
- Drowsiness
- Rapid heart rate
- Shortness of breath
- Tingling sensation in arms and legs
- Blurred vision
What are the types of hypoxia?
Hypoxia literally means "low oxygen" and it can affect specific organs (tissue hypoxia) or the whole body (general hypoxia). There are different types of hypoxia or reasons why there is not enough oxygen in the body tissues. Other types of hypoxia are:
Tissue Toxic Hypoxia
This condition is when the tissues get the right amount of oxygen but cannot use it. For example, cyanide poisoning can cause tissue toxic hypoxia because it prevents the mitochondria from consuming oxygen.
Hypoxia Hypoxia
In this type of hypoxia, the body tissues do not have enough oxygen because there is an overall lack of oxygen in the blood. For example, hypoxic hypoxia is usually caused by insufficient respiration.
Stagnant hypoxia
Stagnant hypoxia is a condition in which there is insufficient blood flow, usually caused by shock, fainting, or other "low flow" states.
What are the causes of anemic hypoxia?
In anemia hypoxia, the oxygen you inhale does not reach all parts of your body adequately due to low levels of hemoglobin in your blood.
This results in a reduced supply of oxygen to your tissues and organs. Causes of anemia hypoxia may include:
- Altitude reactions, where there are not enough oxygen molecules at high altitudes, can prevent the lungs from breathing enough oxygen
- Carbon monoxide poisoning, which prevents hemoglobin from binding to oxygen
- Different types of anemia, such as chemotherapy-induced anemia, iron deficiency anemia, or pernicious anemia
- Bleeding from internal or external injuries
- Hyperventilation is when the body does not breathe enough
- Inability to bind oxygen when hemoglobin is converted to methemoglobin
What are the diagnosis of anemia and hypoxia?
Your doctor has many options to assess the level of oxygen in your blood and determine if you are hypoxic. Laboratory tests can help determine the cause of your symptoms. Some hypoxia tests include:
- Arterial blood gas to test your respiratory and metabolic status
- Blood tests to look for signs of anemia (low red blood cell count) or infection
- Bronchoscopy to look for any signs of obstruction in the airways, such as tumors
- Computed tomography (CT) or magnetic resonance imaging (MRI) of the head to look for brain abnormalities that may inhibit breathing, such as tumors, bleeding or stroke
- An echocardiogram that looks at the heart and looks for damage or abnormalities in the heart or heart valves
- Electrocardiogram to look for any signs of arrhythmia or other heart damage
- Oximetry to track the level of oxygen in the blood
- X-rays or chest CT to look for lung disease or infectio
How to treat anemic and hypoxia?
There are several factors to consider when determining the best treatment for anemia and hypoxia. Once the cause is determined, you can start with the appropriate medications, procedures and therapies.
Your doctor usually recommends oxygen therapy, especially if you have shortness of breath or other symptoms of moderate to severe hypoxia. If your symptoms are severe, your doctor may recommend a mechanical ventilator to help you breathe.
In very severe, life-threatening cases, hyperbaric oxygen therapy may be used. The higher levels of oxygen provided under pressure can sometimes improve blood flow and the distribution of oxygen throughout the body in ways that would not otherwise be possible.
Why do many people choose portable oxygen concentrator?
There are many benefits to using a POC. Most importantly, you can continue an active lifestyle while receiving oxygen therapy. Here are a few examples.
Lightweight
Most portable oxygen concentrators weigh less than 5 pounds and are easy to carry. Featuring a compact design, they fit easily and discreetly into a shoulder bag.
Travels easily
Smaller, lighter portable oxygen concentrators fit comfortably into any suitcase. Most units are FAA approved, so they can be used on domestic and international flights.
High Oxygen Output
Portable oxygen concentrators are available in pulse dose and continuous dose options. The high oxygen output makes them as effective as home units in meeting medical standards for oxygen therapy.
Quiet Operation
Most portable oxygen concentrators are designed for quiet operation, so they can be used on airplanes, in public places and even on long trips without disturbing others.
