Hypoxia and its types

There are many medical conditions and events that interrupt the flow of oxygen to your brain. Stroke, cardiac arrest, and an irregular heartbeat can prevent oxygen and nutrients from traveling to the brain. Other possible causes of oxygen depletion include: • • anesthesia complications during surgery • • • drowning • breathing in carbon monoxide or smoke • traveling to high altitudes (above 8,000 feet) • brain injury • strangulation • medical conditions that make it difficult to breathe, such as extreme Anyone who experiences an event where they aren’t getting enough oxygen is at risk for brain hypoxia. If your job or regular activities involve situations that deprive you of oxygen, your risk is greater. Sports and hobbies Participating in sports where head injuries are common, such as boxing and football, also puts you at risk for brain hypoxia. Swimmers and divers who hold their breaths for long periods of time are also susceptible. Mountain climbers are at risk as well. Medical conditions You’re at risk if you have a medical condition that limits the transfer of oxygen to your brain. These conditions include: • • • Brain hypoxia requires immediate treatment to restore the flow of oxygen to your brain. The exact course of treatment depends on the cause and severity of your condition. For a mild case caused by mountain climbing, for example, you would immediately return to a lower altitude. In more severe cases, you need emergency care that places you on a ventilator (bre...

Some of the broad classes of hypoxia include: Hypoxic hypoxia or generalized hypoxia This refers to hypoxia resulting from an inadequate saturation of blood oxygen due to a reduced supply of oxygen in the air, decreased lung ventilation or respiratory disease. With this type of hypoxia, the partial pressure of oxygen in the arterial blood (paO2) is lower than normal. Some of the causes of hypoxic hypoxia include: • A high altitude, where the concentration of atmospheric oxygen is decreased. • Deep sea diving if there is an inadequate supply of oxygen in the breathing gas or if a rusting cylinder has extracted oxygen, for example. • The inhalation of nitrous oxide or laughing gas on a repeated basis for recreational purposes can decrease oxygen availability while increasing carbon dioxide levels. • Sleep apnea or obstructive sleep apnea can interrupt airflow to the lungs. • Certain disea...

Share on Pinterest Anoxia is when the body or brain does not get enough oxygen. Anoxia is an extreme form of hypoxia. Hypoxia occurs when one part of a person’s body, such as the brain, can only obtain a reduced amount of oxygen. Anoxia occurs when the body does not get any oxygen. This may result in a hypoxic-anoxic injury. A lack of oxygen can cause severe damage or even death, so anyone who suspects they may have hypoxia should seek medical attention immediately. It only takes around A lack of oxygen in the brain causes brain cells to die and can increase the likelihood of brain damage or death. Signs and symptoms following mild anoxia include: • mood swings or changes in personality or judgment • difficulty speaking, slurred speech, or forgetting words • weakness • feeling dizzy or disorientated • an inability to concentrate • memory loss • a • difficulty walking • problems with coordination The longer a person is without oxygen, the more apparent the symptoms will become. Experiencing anoxia for several minutes can cause: • loss of consciousness • collapsing or passing out • seizures • hallucinations It is important to note that the symptoms of anoxia may not be immediately apparent because the brain can compensate for diminished oxygen for a few minutes before any symptoms appear. The initial symptoms may be mild, or a person may ignore them at first. However, immediate medical attention is vital for cases of anoxia. Some of the different types of anoxia are: Anemic ...
