Hypoxia Meaning By Medical
Hypoxia meaning is the condition of the lack of oxygen supply for the body to perform its normal function. Hypoxia may be an advanced condition of hypoxemia, ie low oxygen supply in net blood vessels (arteries).
Hypoxia is a dangerous condition, because the brain, liver, and other organs can be damaged quickly when not getting enough oxygen. This condition can also occur in premature infants, because the lungs are not fully developed.
We must also always be aware of hypoxia when in an environment with low oxygen levels such as mountains, in flight, in the water, or in a fire area.
Symptoms of Hypoxia
Symptoms of hypoxia can suddenly appear, rapidly deteriorate (acute), or are chronic. Here are some of the common hypoxic symptoms:
- Shortness of breath.
- Skin changes color, becomes blue or purplish red.
- Hard to breathe.
- Rapid heartbeat.
- Breath sounds (wheezing).
Hypoxia can also cause complications in case of an error in handling it. Giving excessive oxygen can actually poison the body tissue or commonly called hyperoksia. This can cause:
- Changes in behavior.
If you experience any of these symptoms, consult your doctor immediately for immediate treatment. Although further symptoms are gone, you are still advised to see a doctor.
Causes of Hypoxia
Often, the appearance of hypoxia is caused by hypoxemia. However, it can happen otherwise. In addition to hypoxemia, several things that can cause hypoxia are:
- Gas poisoning or chemicals.
- Low oxygen levels.
- Cardiac disorders such as heart rate slow down quite severe (severe bradycardia) and the contraction of the ventricular fibrillation (ventricular fibrillation) is too fast and irregular.
- Lung impairment, for example chronic obstructive pulmonary disease, bronchitis, emphysema, lung cancer, pneumonia, asthma, pulmonary edema, and sleep apnea.
- Stop or decrease blood flow to certain organs.
- Any medications that interfere with or stop breathing.
- Anemia or conditions that damage red blood cells.
Diagnosis and Treatment of Hypoxia
There are two ways that doctors do to diagnose hypoxia in patients, namely:
- Blood gas analysis. Blood samples from the arteries are examined to determine the levels of oxygen bound in red blood cells.
- Installation of oxygen monitor, on finger or ear of patient to detect oxygen level in blood.
- Pulmonary function test. This test is done to determine the cause of reduced oxygen in the body.
If you feel hypoxic, you should immediately go to the hospital so that the levels of oxygen in the body can be monitored and get treatment as soon as possible. There are several treatments that doctors will do for people with hypoxia, namely:
- Supplying oxygen to the body. The body of the hypoxic patient will be supplied with oxygen using a hose or oxygen mask. The faster the oxygen levels in the body return to normal, the less risk of organ damage.
- Hyperbaric space. People with hypoxia caused by carbon monoxide poisoning will usually be put into hyperbaric chamber, which works to increase oxygen in the blood.
- Intubation. Create a mechanical airway that serves to deliver oxygen with above normal levels.
Prevention of hypoxia can be done by avoiding conditions that lower oxygen levels, or immediately provide oxygen supply before hypoxia occurs. Hypoxia caused by asthma can be avoided by following asthma therapy that has been prescribed by a doctor. The therapy can also help the patient control asthma.
