In addition, pollution from outdoors, such as motor vehicle exhaust, can enter buildings, worsen indoor air quality, and increase the indoor concentration of carbon monoxide and carbon dioxide. [16] Adult SBS symptoms were associated with a history of allergic rhinitis, eczema and asthma. [17]
Carbon monoxide also binds to the hemeprotein myoglobin. It has a high affinity for myoglobin, about 60 times greater than that of oxygen. [21] Carbon monoxide bound to myoglobin may impair its ability to utilize oxygen. [49] This causes reduced cardiac output and hypotension, which may result in brain ischemia. [21]
Respiratory damage is related to the concentration of the gas and its solubility. Irritant gas exposures predominantly affect the airways, causing tracheitis , bronchitis, and bronchiolitis . Other inhaled agents may be directly toxic (e.g. cyanide , carbon monoxide ), or cause harm simply by displacing oxygen and producing asphyxia (e.g ...
The primary health concerns associated with carbon monoxide exposure are its cardiovascular and neurobehavioral effects. Carbon monoxide can cause atherosclerosis (the hardening of arteries) and can also trigger heart attacks. Neurologically, carbon monoxide exposure reduces hand to eye coordination, vigilance, and continuous performance.
The value of 615 ppm above the outdoor concentration indicates approximately 15 cubic feet per minute of outdoor air per adult occupant doing sedentary office work where outdoor air contains over 400 ppm [123] (global average as of 2023). In classrooms, the requirements in the ASHRAE standard 62.1, Ventilation for Acceptable Indoor Air Quality ...
Frank McCutcheon, 53, and Brett McCutcheon, 32, have been accused of causing the death of Jonathan Rodriguez, a 21-year-old student from Dupont who died from carbon monoxide poisoning on Dec. 11 ...
Breath carbon monoxide device. Breath carbon monoxide is the level of carbon monoxide in a person's exhalation. It can be measured in a breath carbon monoxide test, generally by using a carbon monoxide breath monitor (breath CO monitor), such as for motivation and education for smoking cessation and also as a clinical aid in assessing carbon monoxide poisoning.
