“…Gozubuyuk et al (2017) supposed that, symptoms of poisoning are linked to carboxyhaemoglobin level. However, Köthe and Radke (2010) considered initial COHb level as an inaccurate reflection of a patients' exposure because COHb levels decrease with time and with oxygen treatment. On the other hand, duration of hospital stay had no significant correlation with REMS, MEWS and SCS.…”

Background: Carbon monoxide (CO) poisoning is one of the most common fatal poisoning worldwide. Laboratory parameters and imaging studies have been used to predict late cardiac and neurological complications in CO poisoned patients. However, very few studies have applied scoring systems as predictors of CO poisoning outcome. Objectives: To evaluate various scoring systems used in emergency settings [Rapid Emergency Medicine Score (REMS), Modified Early Warning Score (MEWS) and Simple Clinical Score (SCS)] for outcome prediction in acute CO poisoned patients. Methodology: It was a cross-sectional study that was conducted on forty five acute CO poisoned patients. It was composed of two parts; retrospective (From 1 st of January 2020 to 28 th of February 2021) and prospective part (From 1 st of March 2021 to 30 th of June 2021). Patients with major medical conditions, pregnant females, smokers and those exposed to associated trauma and other substances in addition to CO were excluded. Using patients' data on admission, REMS, MEWS and SCS were calculated and compared for prediction of outcome. Results: On admission REMS, MEWS and SCS showed significant elevation in both mechanically ventilated and non-survivors when compared to nonmechanically ventilated patients and survivors. MEWS was excellent predictor for requirement of mechanical ventilation (AUC > 0.9). For mortality prediction; REMS, MEWS and SCS were all excellent (AUC = 1). Conclusion: REMS, MEWS and SCS are simple, rapid, reliable and applicable scoring system in predicting mechanical ventilation requirement and in-hospital mortality in acute CO poisoning.

“…According to the Occupational Safety and Health Administration (OSHA) regulations of the United States Department of Labor, the concentrations of CO and NO gas in a workplace should not exceed 35–50 ppm and 30–45 ppm, respectively. CO and NO, which are colorless, tasteless, and have nonirritant properties, [ 3–7 ] are toxic gases. If people are exposed to a CO and NO gas environment for a long time, these gases dissociate into their blood and combine with hemoglobin (Hb) to reduce the oxygen‐carrying capacity of the blood.…”

Over the past few decades, ambient air pollution (AAP) sources, including exhaust fumes, toxic air, and particulate materials (PMs), have increased due to power generation, vehicle emissions, and the gas industry. This has compromised environmental safety. In 2018, the World Health Organization (WHO) reported the effects of AAP and household air pollution (HAP) on human health. According to these reports, outdoor air pollution has not only gradually changed our living habits, but also increased the probability of death and diseases, including lung cancer, strokes, ischemic heart disease, and acute respiratory infections. Another report from the WHO in 2016 mentioned that AAP and HAP had caused the death of 543 000 children under the age of 5 years. [1,2] These reports indicate a direct link between AAP, HAP, and human health. HAP includes volatile organic compounds, PMs, CO, SO 2 , and NO. Cooking, heating, and burning solid or liquid fuels such as wood, coal, kerosene, and gasoline generate large amounts of pollutants, which strongly impact human health, especially that of young children and people who spend majority of their time indoors. According to the Occupational Safety and Health Administration (OSHA) regulations of the United States Department of Labor, the concentrations of CO and NO gas in a workplace should not exceed 35-50 ppm and 30-45 ppm, respectively. CO and NO, which are colorless, tasteless, and have nonirritant properties, [3-7] are toxic gases. If people are exposed to a CO and NO gas environment for a long time, these gases dissociate into their blood and combine with hemoglobin (Hb) to reduce the oxygen-carrying capacity of the blood. Hence, it is important to prevent or minimize HAP. To reduce AAP and HAP (CO, SO 2 ,and NO x), semiconductor materials (ZnO, TiO 2 , and SnO 2) could be converted into high porosity polycrystalline nanofibers (PNFs), which have many advantages, including a nanointerface between nanograins, [8,9] wide band gap (3.6 eV), and generation-recombination centers, owing to the defects and dangling bonds at the end of nanograin's surface. Recent studies on the development and application of PNFs suggest that they can be used in photonic devices, such as photon sensors [10-13] and solar cells, [14,15] as well as non-photonic devices, such as PM filters, [16,17] toxic gas sensors, [18-34] biological sensors, [35-39] RRAM devices, [40,41] and energy devices. [42-49] The indoor ambient temperature for the majority of households is ≈25-30 °C. According to Yang and co-workers [50] and Moon et al., [29] SnO 2 and TiO 2 The development of SnO 2 and TiO 2 polycrystalline nanofiber devices (PNFDs) has been widely researched as a method of protecting humans from household air pollution. PNFDs have three significant advantages. The nanofibers before the annealing process are polymer-rich materials, which can be used as particulate material (PM) filters. The multiporous nanofibers fabricated by the annealing process have numerous defects that can serve as generation-recombination c...
