Death typically occurs due to problems with the nervous system or the heart. Post mortem analysis of blood of poisoned people shows that concentrations of about 3 micrograms cyanide per ml were sufficient to kill the person.
Incorporation of cyanide, mainly HCN, via the breathing, is a lot more rapid than via ingestion. A person will die instantly if the HCN concentration is above ppm, Parts per million , and after 10 and 30 minutes respectively if the HCN concentrations are respectively and ppm.
Since cyanides effect the function of muscles and produce confusion, many victims die because they lose their coordination and ability to escape to areas with clean air.
This happens sometimes when people are trapped in a burning house and the air contains cyanide. If it is suspected that a victim was poisoned by ingesting cyanide, it imperative that it will be determined QUICKLY since the poisoning effect of cyanide is very quick.
To this end, Appealing products Inc. These detectors allow emergency personnel to react timely and save the victim. The KT kit detects cyanides and up to 30 other poisons.
The STPD detects the same poisons but has a much shorter shelve life. The CAK kit detects only cyanides, azides, sulfides and chromates. ChemSee now also offers home-users the ability to test their foods directly for Cyanide using the CN Detector. More information on the CN Detector can be found below:.

Cyanides may be detected using conventional laboratory techniques and instruments. Unfortunately, these techniques require expensive and sophisticated instrumentation and highly trained personnel and the results are NOT obtained immediately. Since in real emergency situations such amenities may not be available, and a timely response is critical to save a person live, the value of the laboratory services is mainly in post mortem investigations.
Since the poisoning mechanism of cyanides is based on the reaction of the free cyanide ion with metals, mainly iron and thus preventing the proper absorption and assimilation of oxygen, antidotes to cyanide poisoning utilize injecting relatively large amounts of metallic ions which rapidly and irreversibly react with the cyanide ion.
This process depletes the concentration of the cyanide ions in the blood and thus reduces the amount of cyanide available for reaction with the iron and deactivating it. The most important qualities of a good antidote for cyanide poisoning are:. One of the antidotes used today is hydroxocobalamin, a naturally available form of vitamin B This compound reacts with cyanide to form cyanocobalamin, which is eliminated safely by the kidneys.
The cyanide reacts with the cobalt in the hydroxocobalamin and thus consumed and becomes unavailable to react with the iron. An antidote kit based on this chemistry is sold under the brand name Cyanokit and was approved by the FDA in The most important mechanism which eliminates cyanide from the body involves the enzymatic conversion of the cyanide to the relatively non-toxic thiocyanate ion.
CNS After discussing your symptoms, your doctor will perform a physical exam. The first step to treating a suspected case of cyanide poisoning is to identify the source of exposure.
This will help your doctor or other healthcare provider determine the appropriate decontamination method. In the case of a fire or other emergency incident, rescue personnel will use protective gear like face masks, eye shields, and double gloves to enter the area and take you to a safe location.
If you have ingested cyanide, you may be given activated charcoal to help absorb the toxin and safely clear it from your body. Cyanide exposure can affect oxygen intake, so your doctor may administer percent oxygen via a mask or endotracheal tube. The cyanide antidote kit consists of three medications given together: amyl nitrite, sodium nitrite, and sodium thiosulfate.
The amyl nitrite is given by inhalation for 15 to 30 seconds, while sodium nitrite is administered intravenously over three to five minutes. Intravenous sodium thiosulfate is administered for about 30 minutes. Hydroxocobalamin will detoxify cyanide by binding with it to produce nontoxic vitamin B This medication neutralizes cyanide at a slow enough rate to allow an enzyme called rhodanese to further detoxify cyanide in the liver. If you suspect you or a loved one is experiencing symptoms of severe cyanide poisoning, seek immediate emergency medical attention.
Your outlook will depend on the type of cyanide present, the dose, and how long you were exposed. Early diagnosis and treatment are key to reducing your risk of complications. Moderate levels of acute or chronic exposure may also be resolved with quick diagnosis and treatment. In severe cases, symptoms are often sudden and life-threatening. Cyanide intoxication is largely a clinical diagnosis; however, several laboratory features are suggestive:.
Cyanide blood levels are confirmatory, as results are not obtainable in time for initial diagnosis. There are some reports of use of rapid calorimetric paper test strips to confirm the presence of cyanide. Before cyanide antidote can be administered, the patient must be removed from the cyanide-laden area, clothing removed, and skin washed with soap and water.
If cyanide salts have been ingested, activated charcoal may prevent absorption from the gastrointestinal tract. There are 2 major modalities of treatment: the cyanide antidote kit and hydroxocobalamin.
Although recovery from a chemical attack is rare, victims may survive sub-lethal exposures, whether from ingestion, smoke inhalation, or exposure to cyanide-containing industrial products, such as carpet. Patients who are treated successfully for cyanide poisoning should be observed for development of long-term neuropsychiatric symptoms that are similar to symptoms experienced by survivors of cardiac arrest or carbon monoxide poisoning.
