Are Iranians Aware of Carbon Monoxide Poisoning: Symptoms and Its Prevention Strategies?

Abstract

Carbon monoxide (CO) poisoning is still a health problem all over the world. Informing users about symptoms and suggesting annual inspection of CO producing devices will result in CO poisoning reduction. The goal of this study was to evaluate awareness about CO poisoning symptoms and its prevention ways in Iranian population. In this study, a total of 700 patients' family members attended Imam Khomeni hospital were asked to enroll in the study. A structured questionnaire was used including demographic characteristics, devices which were used at home, awareness of CO poisoning symptoms, awareness of CO detectors, the last time that tubal patency of devices are checked, if it is helpful to open the window to fix gas leak and if surveying devices by an expert at the beginning of the cold season is recommended. A total of 635 participants completed questionnaires. The most used device was gas water heater followed by gas heater. Five hundred and nine reported that they are aware of CO poisoning symptoms (80.1%), 398 (62.6%) stated that it is possible to detect CO leak and 566 (89.1%) told CO detectors would be helpful for reduction of mortality from CO poisoning. Fifty percent of participants had not checked their devices since they have bought their devices. Five hundred and thirty-six (84.4%) reported that opening window could help CO leak, and 596 (93.8%) agreed that an expert checked their fuel-burning devices at the beginning of the winter. Iranian people are not aware of all CO poisoning symptoms. Developing a national strategy for CO surveillance and people education will be helpful.
