Airflow obstruction after smoke inhalation

Importance of airflow obstruction after thoracoplasty.

Thirty six patients previously treated for pulmonary tuberculosis by thoracoplasty were studied to determine the prevalence and effect of airflow obstruction. The mean (SD) FEV1 was 1.3 (0.65) 1 and the mean forced expiratory ratio (FER) 64% (12%). FEV1 was less than predicted in every patient whereas FER was less than predicted in 30, being below the lower 98th percentile in 15 (42%). In the 1...

Cardiopulmonary Dysfunction After Smoke Inhalation Injury

With the inhalation of smoke, there are both cardiopulmonary changes and elevated levels of carbon monoxide (CO). We hypothesize that these changes in cardiopulmonary function are the result of a histotoxic hypoxia associated with CO poisoning. This hypothesis was tested in chronically instrumented sheep (n= 19). Piezoelectric crystals were attached to the left ventricle for the measurement of ...

Chronic airflow limitation after inhalation of overheated cooking oil fumes.

Defining airflow obstruction.

The authors of the article published recently in the European Respiratory Journal on the prevalence and correlates of airflow obstruction in >317 000 never-smoking Chinese subjects concluded that they found inconsistent associations with exposures to household air pollution and went on to outline what future work needed to be done [1]. In the first instance, they should present table 5 having r...

Defining airflow obstruction.

Using a very large number of predominantly Chinese nonsmoking females aged 30–79 years, SMITH et al. [1] studied the relationship between airflow obstruction, household air pollution, household income, educational level and prior tuberculosis. They defined airflow obstruction as a ratio of forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) of <0.7 or <5th percentile, and grad...
