Three questions regarding CO poisoning were posed to a 30-person ACEP subcommittee, which employed a comprehensive literature review to attempt to draw conclusions. While this is a major step forward, we feel that their conclusions warrant comment.

We sought to compare ambient CO levels produced by automobiles with and without catalytic converters in a residential garage, as well as from other CO sources commonly used for intentional poisoning. Methods: CO levels were measured inside a free-standing 73 m3 one-car garage. CO sources included a 1971 automobile without CC, 2003 automobile with CC, charcoal grill, electrical generator, lawn mower and leaf blower. Results: After 20 minutes of operation, the CO level in the garage was 253 PPM for the car without a catalytic converter and 30 PPM for the car equipped with one. CO levels after operating or burning the other sources were: charcoal 200 PPM; generator >999 PPM; lawn mower 198 PPM; and leaf blower 580 PPM. Conclusions: While emissions controls on auto...

Unfortunately, this disorder is commonly undiagnosed, resulting in significant excess morbidity and mortality. The clinical symptoms and signs caused by pulmonary embolism are nonspecific and may be confused with a variety of other cardiopulmonary disorders having similar presentations. However, accurate diagnostic tests are available for diagnosing pulmonary embolism, even in the face of coexistent cardiopulmonary disorders. This article describes the clinical characteristics of pulmonary venous thromboembolism, reviewing its typical symptoms and signs, its routine laboratory tests, and chest radiographic abnormalities.

Intravascular hemolysis with associated endogenous carbon monoxide (CO) production resulted in elevation of the patient's carboxyhemoglobin (COHb) level to as high as 9.7%. Serial measurements of the patient's COHb level were obtained and compared with other conventional measures of hemolytic activity. With the availability of new non-invasive measurement technology to detect COHb elevations, emergency clinicians are likely to see COHb elevation as a manifestation of hemolytic anemia.

Cases of patients referred for treatment of CO poisoning with hyperbaric oxygen were reviewed. Those cases that occurred during recreational boating were selected for analysis. A private, urban, tertiary care center studied from July 1984 to June 1994. Thirty-nine patients ranging in age from 6 months to 69 years who were poisoned in 27 separate incidents. Characteristics of the poisoning incidents were assessed at initial patient presentation, immediately following treatment, and with follow-up telephone interviews. Of 512 patients treated for acute unintentional CO poisoning, 39 cases (8%) occurred in 27 incidents related to recreational boating activities. Individuals typically lost consciousness as a result of the poisoning. Most cases occurred aboard a boat that was older than 10 years, had an enclosable cabin, was longer than 22 feet, was powered by a gasoline engine, and was without a CO detector on board. Carbon monoxide poisoning is a serious hazard associated with recreational boating. The installation of CO detectors aboard boat types typically associated with this syndrome should be strongly encouraged.

It may be a potential therapy for radiation necrosis seen after brain irradiation. HBO2 risks include generalized tonic–clonic convulsions. We report a patient after resection of anaplastic astrocytoma and 5,580 cGy of total external‐beam radiation treatments with brain radiation necrosis who underwent HBO2 therapy and developed a partial seizure during treatment. Mechanisms and implications are discussed.
