How to diagnosed carbon oxide poisoning


The sampling of carbon monoxide diagnostics is more complicated than it sounds. Theoretically, the effects of carbon monoxide lead to high levels of carbon monoxide in the bloodstream, and this is a diagnosis.The reality is that the impact of carbon monoxide is both the concentration (insofar as humidity in the air) and time (as a patient breathes a lot),This means that the diagnosis of carbon poisoning is an oxide is a combination of signs signs. And the symptoms, as well as measure the amount of co in the bloodstream.

No Logging / AT-Home tests

Nevatarious diagnosis for carbon monoxide poisoning, but any confusion or loss of consciousness must have 911 for them 911.

You must suspect carbon oxide poisoning, if more than one person in a building with a source of combustion (oven, fireplace, gas devices, wood, etc.) complain of nausea.

If carbon monoxide is intended to poison, all the housings of the building must come out to breathe fresh air, and also call 911. If you suspect that the poisoning per co , Do not attempt to drive; It calls an ambulance.

CO In the blood

Carbon oxide (CO) is associated with a symilot hemoglobin, as oxygen does.However, the difference in significance, the hemoglobin has 230 times with affinity per coly that for oxygen. This means that even a small amount of carbon inhaled will be born with hemoglobin, blocking oxygen in the process.

Hemoglobin, which is attached to the CO called carboxyhemoglobin (COHGB). The measurements of the amount of COHGB in the blood are used to detect carbon monoxide in the blood and determine how hard the poisoning is .

First test of the respondent

Some of the first respondents have the ability to measure carboxigemoglobin in the blood using a device called hydroxyis of pulse carrot. In particular, the pulsed nomer measures the carbon oxide saturation in hemoglobin (SPCO). Use light waves (usually bright supports) to measure non-invasive saturation of carbon oxide.

Another form of non-invasive measurements uses exhaled air to determine carbon monoxide levels. Some studies have discovered that they exhaled to be inaccurate as determine the carbon poisoning oxide.

spco is not significantly measured by all the first respondents, therefore, the history and physical examination are still the gold standard on the scene.

The traditional pulse oximetry used to measure only if the hemoglobin is saturated with a donkey or index or unsaturated, it is fascinated by carbon monoxide poisoning in showing a saturation of artificially high oxygen,When carboxyhemoglobin is present. This makes it even more important to get a good history and a physical examination of the patient.

Laboratory tests

In the hospital, more invasive, but a more accurate test is used. This is called gas gas.

Gas tests in the blood measured the amount of atmospheric oxygen gas and carbon dioxide in blood flow, drawing blood from the arteries.Most other blood tests extract blood from the veins, which are easier and safer for the patient.

Blood blood chiarte tests are a standard for oxygen and carbon dioxide, because these gases change significantly before and after the blood flows through the Body tissues.

arterial An leateurial that the venous mermeling potential for hemoglobin for the supply of oxygen and eliminate carbon dioxide.Since carbon monoxide is not easily used or easily removed from the bloodstream, it can be verified through arterial or venous blood. Gas gas tests in the blood are considered more accurate than the COOC of pulsed coding. , Although oximetry is useful for identifying patients in the stage, which potentially has a poisoning of the carbon office, blood gases should be obtained to confirm The levels of carboxygemoglobin.


Acute official carbon poisoning, which comes from high concentrations of carbon monoxide in relatively short impact periods, is not the only effect of carbon.The chronic (long-term) carbon carbon effects with much lower concentrations can cause tissue damage, especially to the heart and brain.

, although carboxyhemoglobin levels in the chronic exposure of patients can be lower than those of sharp patients, there are other forms of Detect damage. The most common is to look at the fabric through medical visualization.

Magnetic resonance display (MRI) is the best way to study the brain for potential injuries of carbon monoxide poisoning.

Differential Diagnostics

Due to the non-recognition of most signs and symptoms of related to carbon oxide.The high concentration of carbon monoxide in the patient’s house will offer the possibility of carbon monoxide poisoning, , but other reasons that should still be excluded.

The list of differential diagnoses is too broad for identification. Each case is different and should be estimated on the basis of presentation, history and test patient.

Frequently asked questions

  • To determine how wet oxide can be in the human body, the doctor will measure carboxyhemoglobin (cohgb) levels in your blood.This compound is formed when carbon monoxide is associated with a <α> hemoglobin , red blood cell protein, which carries oxygen.According to the Centers for Disease Control and Prevention and Prevention, ‘the increase in non-compliance of 2% of 2% and 9% for smokers strongly supports the diagnosis of co-poisoning.’

  • can not auto-name co poinage by CO, but there are signs and symptoms you can know.These symptoms can also provide a tip to the amount of carboxyhehemoglobin (cohgb) in your blood: / P>

    • 10% 20%: Pain head and nausea
    • Levels of more than 20%: muscle weakness, dizziness,Concentration problems, and degradation of levels
    • exceeds 30%: dyspnea (shortness of breath), confusion and chest pain (if you have coronary artery from ishebs )
    • higher levels: syncope (fainting), cramps,And changed consciousness ( we will define

    damage the cumulative corpus: if the levels of the cohgb exceed 60%, hypotension blood pressure ) Coma, respiratory insufficiency and death may arise.

  • cyanos is a colorless gas, which inhaling in large quantities prevents the cells in the body to use oxygen, very similar to carbon monoxide.If it is suspected that cyanide poisoning is suspected, it can be detected with a complete blood test, but since cyanide is eliminated from the blood quickly, the tests must be performed immediately.The poisoning against cyanide can occur together with carbon monoxide intoxication in certain cases, such as the fire of the house, but more difficult to diagnose.

    cyanide is a colorless gas, which, when inhaled in large quantities, prevents cells in the body to use oxygen, such as oxidizing Avgar.If it is suspected that cyanide poisoning is suspected, it can be detected with a complete blood test, but since cyanide is eliminated from the blood quickly, the tests must be performed immediately.Enoxylation against cyanide can occur with the poisoning of carbon monoxide in certain cases, such as fire at home, but it is more difficult to diagnose.
