A third of all burn victims admitted to a hospital are affected by pulmonary injury from inhaling smoke and fatality from inhalation injuries is higher than burn injuries - mortality exceeds 50% for burn victims with severe burn and inhalation injury. Tissue oxygenation is significantly affected and thermal injury to the upper airways, lower airways, and lung parenchyma occurs. Poor tissue oxygenation is a life-threatening conditions and results from inhaling carbon monoxide, cyanide, a gas mixtures devoid of  oxygen, or from an imbalance between alveolar ventilation and blood supply. Carbon monoxide is a colorless and odorless gas, which can interfere with and impede respiration. Oxygens tendency to bind with hemoglobin is 250 times less than carbon monoxide, severely reducing the quantity of circulating oxygen and limiting tissue oxygenation in carbon monoxide poisoning. Exposure can be deliberate (suicidal) or accidental and can come from automobile exhaust pipes, inhaling smoke during a fire accident, and poorly vented gas heaters, generators, and other appliances.Cyanide is inhaled into the lungs in gaseous form – as hydrogen cyanide. Cyanide can also be diffused through the skin or ingested. Rapid infusion of high-dose cyanide cause cyanide poisoning. It is produced when nitroprusside is broken down into its constituents. It inhibits cells from properly utilizing oxygen by disrupting cytochrome oxidase, and can be more damaging to the brain and heart.Cyanide is a highly toxic chemical often used in industries and in laboratories. Finger nail glue remover products contain acetonitrile and its metabolic break down produces cyanide.
Her case is mentioned in Nicolas-François and Geneviève Regnaults Les écarts de la nature, published that year. Her full lifespan is unknown, but is mentioned to still be alive in French publications as late as 1777. Lali Singh
Lali Singh (10 March – 10 May 2008) was born to Sushma and Vinod Singh in Saini, Sunpura Sohanpur village, near Delhi; the birth was delayed by dystocia caused by her large head, and her birth in a hospital was facilitated by her mothers receiving an episiotomy. She was one of the very few infants with diprosopus to survive well past birth, and may have been the only known living individual with complete facial duplication. Her facial features included two pairs of eyes, two noses, and two mouths (but only one pair of ears). She was seen as the reincarnation of the goddess Durga, who is sometimes depicted with many limbs and eyes. Sushma and Vinod Singh declined an offer from local doctors to evaluate their daughter through CT or MRI scanning. Without diagnostic imaging, it was not possible to know the full extent to which the childs condition might have affected her brain and other vital structures in her head and neck. Thus, any estimation of her ability to thrive or even survive could be only speculative, though Lalis family described her as functioning normally. It is also unknown whether neurosurgeons or craniofacial surgeons, if consulted, would have had feasible solutions to offer with respect to corrective surgery.
