Suicide by carbon monoxide
Nh father, son deaths ruled murder-suicide by carbon
The authors address the case of a 29-year-old man who committed suicide due to carbon monoxide (CO) poisoning. The authors were fascinated by the unconventional method of suicide, which required advanced technical expertise and expert knowledge.
The amount of carboxyhemoglobin (COHb) in the blood of the deceased man was routinely calculated using gas chromatography/thermal conductivity detection, as updated by Blackmoore (1970). The amount of CO saturation of hemoglobin in the collected blood sample is measured in contrast to a sample saturated to 100%.
The lethal concentration of COHb in the blood of the deceased man was found to be 76.5 percent. A blood alcohol concentration of 0.05 g.kg(-1) was determined in the following experiments. Further tests found traces of sertraline, its metabolite N-desmethylsertraline, omeprazole, and caffeine in liver tissue, traces of N-desmethylsertraline, ibuprofen, and caffeine in semen, and only traces of caffeine in stomach content and blood samples. The man used a sophisticated double container-system with a timer for controlled CO generation based on the chemical reaction of condensed sulphuric acid and formic acid to commit suicide. The timer was set by an electromechanical timer switch, which caused the acids to respond fatally while the man slept.
Carbon monoxide death
Acute carbon monoxide (CO) poisoning is one of the most common causes of death in toxicology. CO is usually produced by incomplete combustion of carbonaceous materials, which is the most common method used in suicide attempts. This is an exceptionally unusual case of a suicide attempt involving the deliberate combination of formic and sulfuric acids to create carbon monoxide. Inhalation of carboxyhemoglobin (COHb) levels ranging from 64 to 93 percent, as well as caustic injury, has been reported to be virtually uniformly fatal in previous case studies.
At 10:30 a.m., family members discovered a 27-year-old female medical student unresponsive in her car. Her sister last saw her less than 12 hours ago, journaling in her bed. Later, it was revealed that she was writing her suicide note. She was discovered unresponsive in the backseat of the car with the engine turned off, according to the EMS article. The end of a tube running from a 5-gallon drum containing a green “oily” fluid lay next to her face. First responders found labelled containers of formic and sulfuric acid on the scene. Despite following standard HAZMAT protocol, they ventilated the car for scene safety and registered residual CO levels of 150-200ppm. The patient’s initial assessment showed a GCS of 8. (E2V2M4). COHb was 17 percent when I arrived at the nearest hospital ED. For airway safety, she was intubated. She was moved to the University of Pennsylvania for hyperbaric oxygen therapy due to the seriousness of the exposure and her presentation (HBOT). Our initial assessment of an intubated age-appropriate female with decerebrate posturing was important.

The aim of this study is to present an unusual case of a suicidal use of gases from a car exhaust system in an open space. Intervention and Clinical Presentation: An experimental reconstruction of the crime scene was carried out to confirm the suicidal motive of the poisoning. This showed that prolonged exposure to carbon monoxide in the midst of unfavorable weather would result in acute carbon monoxide poisoning in an open room. Conclusions: The pattern of fatal carbon monoxide poisoning in an open space was studied in this case. Forensic medicine, emergency medicine, and occupational medicine may all benefit from this.

Father killed self, son with carbon monoxide; left note warning
The aim of this article was to provide a general overview of the literature on carbon dioxide intoxication. The emphasis of the articles was on the medical or physiological effects of carbon dioxide. Decompression sickness studies were not included. Carbon dioxide poisoning mechanisms (both as an asphyxiant and a toxicant) were identified. When working with dry ice or in enclosed spaces, our investigation found that safety precautions are necessary. For their own protection, pre-hospital responders must also be conscious of the risk of CO2 intoxication. When faced with a survivor, get him or her out of the dangerous area as soon as possible and give him or her oxygen. Victims can experience acute cognitive impairment, respiratory failure, and circulatory collapse if not treated properly. As a result, carbon dioxide poisoning is an uncommon but essential diagnosis to make in the emergency room.
