T1 C+ (Gd): can show patchy peripheral enhancement in affected areas in the acute phase 2ĭWI: affected areas show increased diffusion signal in the acute phase RM D05EAC Trees poisoned by carbon dioxide at Horseshoe Lake, near Mammoth Lakes, California. Ball-and-stick models, geometric structures and formulas.
T1: affected areas are usually low signal, hemorrhagic areas can be high signal Quick filters: Cut Outs Vectors Black & white RF PR3JW9 Carbon monoxide CO and carbon dioxide CO2 molecule models and chemical formulas.

Millions of high-quality images, video, and music options await you. Other features include diffuse hypoattenuation in cerebral white matter 4. Certain types of cleaners are only harmful if ingested, while others also emit toxic gases/fumes. Many substances such as drugs and carbon monoxide are poisonous only in higher concentrations or dosages. CTĬlassically seen as low attenuation in the globus pallidus region. Poisoning is injury or death due to swallowing, inhaling, touching or injecting various drugs, chemicals, venoms or gases. Clinical presentationĪcute symptoms of headache, dizziness, altered conscious state, seizuresĬardiac arrest may occur, see pulseless electrical activity (PEA)Ĭhronic symptoms of cognitive decline, abnormal gait, fecal incontinenceĬarbon monoxide strongly binds to hemoglobin and the resultant carboxyhemoglobin in the bloodstream can cause profound hypoxic/anoxic injuryĬarbon monoxide is also a respiratory chain metabolism toxin that interferes with mitochondrial oxidative phosphorylation and activates polymorphonuclear leukocytes, which undergo diapedesis and cause brain lipid peroxidation this results in the delayed effects of carbon monoxide poisoningĬhanges tend to be bilateral with the globus pallidus most commonly affected 2. It is also observed as an attempt to commit suicide. Normally, the blood contains 40 millimeters of mercury (mm Hg) of carbon dioxide. Carbon dioxide is a waste product of the metabolic process of cells. EpidemiologyĬarbon monoxide poisoning is mostly preventable with common causes including malfunctioning heating systems, improperly ventilated motor vehicles, and residential fires 9. Hypercapnia Victims of carbon dioxide poisoning die of hypercapnia, a condition in which there is too high a buildup of carbon dioxide in the blood. Gas geyser syndrome is a term used to describe symptoms of carbon monoxide poisoning while bathing due to carbon monoxide production from liquefied petroleum gas geysers used to heat water 11.
