A Relationship between a Level of Carboxyhemoglobin and Hemoglobin in Bus Mechanics

Abstract Carbon monoxide (CO) is a highly toxic gas; the result of incomplete combustion emitted from motor vehicle fumes. Bus mechanics are workers who are at risk of CO exposure from motor vehicle fumes. This gas will enter the bloodstream and bind Hemoglobin (Hb) to Carboxyhemoglobin (COHb). This can reduce the capacity of the blood to send oxygen to body tissues. As compensation, the body will increase the process of erythropoiesis, which can increase Hb production. The purpose of this study was to determine the average picture of COHb, Hb levels, and the relationship of increased levelsCOHb with Hb levels in bus mechanics in Tasikmalaya. Design research uses a cross-sectional approach against 30 subjects. Examination of the level of COHb and Hb in laboratory STIKes Muhammadiyah Ciamis. Subjects exposed to CO with an average COHb level of 42.3 mg / L and an average level of Hb of 14.0 g/dL. Statistical test results show no relationship between COHb levels with an increase in Hb levels in bus mechanics in Tasikmalaya p >0.01 (p = 0.573; r = 0.107). Conclusion, the average COHb level in bus mechanics in T asikmalaya exceeds the allowable limit, while the Hb level is still in the reference value and an increase in COHb level not obtained with an increase in Hb.
