Toxicological approach to setting spacecraft maximum allowable concentrations for carbon monoxide [PDF]
The Spacecraft Maximum Allowable Concentrations (SMACs) are exposure limits for airborne chemicals used by NASA in spacecraft. The aim of these SMACs is to protect the spacecrew against adverse health effects and performance decrements that would ...

Carbon Monoxide: Present and Future Indications for a Medical Gas [PDF]
, 2013 Gaseous molecules continue to hold new promise in molecular medicine as experimental and clinical therapeutics. The low molecular weight gas carbon monoxide (CO), and similar gaseous molecules (e.g., \(H_2S\), nitric oxide) have been implicated as ...

Simplified determination of carboxyhemoglobin.
Clinical Chemistry, 1984 Abstract This spectrophotometric method for estimating carboxyhemoglobin is based on the production of a two-pigment mixture by reducing oxyhemoglobin and methemoglobin with sodium hydrosulfite . Absorbances of the pigment are measured at 420 and 432 nm. Protecting the solutions against exposure to air is unnecessary.

Physiological Reports, Volume 13, Issue 9, May 2025.Abstract Exposure to charcoal biomass (CB) pollutants affects the cardiorespiratory system. We assessed cardiopulmonary responses (CPR) to exercise in charcoal producers (CPs) compared to farmers and evaluated the prevalence of exercise‐induced bronchoconstriction (EIB).

[Reference values for carboxyhemoglobin].
Revista de saude publica, 1997 INTRODUÇÃO: Os valores de referência de indicadores biológicos são utilizados como parâmetros para interpretação de resultados de valores obtidos em indivíduos expostos ocupacionalmente aos agentes químicos. O Grupo Brasileiro para Estabelecimento dos Valores de Referência tem se dedicado a estas determinações objetivando estabelecer valores de ...

Toxicity of the pyrolysis products of spacecraft materials [PDF]
A number of spacecraft construction materials are evaluated for the toxic effects of their thermodegradation products on rats. Pyrolysis toxicity testing of pyrolysate fumes establish carbon monoxide, carbon dioxide and hydrogen cyanide as the most ...

Carbon Monoxide Poisoning Effectively Treated with High-flow Nasal Cannula Oxygen [PDF]
, 2020 Carbon monoxide (CO) poisoning is typically treated by administration of oxygen via non-rebreather mask (NRB). High-flow nasal cannula (HFNC) is an alternative to NRB in a variety of disease states.

Carbon Monoxide in the Ambient Air and Blood Pressure: Evidence From NHANES II and the SAROAD System [PDF]
Prior to 1985, ten states adopted some kind of indexing provisions for their personal income tax systems. Seven of these states subsequently suspended their indexing laws for one or more years.

Determinants of fibrinogen in an Italian population suffering from claudication. Lower fibrinogen in the south compared to middle and north of Italy. The ADEP Group. [PDF]
, 1998 Prospective studies have shown that high plasma levels of fibrinogen are independently associated with the risk of cardiovascular complications. In patients suffering from peripheral vascular disease (PVD) fibrinogen has been shown to be an independent ...
