Abstract:
Approximately 20 million nonsmoking workers are employed in workplaces without restrictions on smoking and are potentially exposed to secondhand smoke--a Class A carcinogen. These workers are largely in the service industry, in southern and western states and in non-urban areas. The Occupational Safety and Health Administration's (OSHA's) 1994 proposal for smoke-free workplaces (withdrawn in 2001) was attacked by many interest groups that may no longer oppose this protection. Federal regulation for smoke-free workplaces is needed for workers, who are not protected by state and local smoke-free laws. This policy could save thousands of lives each year, and prevent significant illness. Twenty-one states have "state plans" that would allow more protective laws. Of the 29 states under OSHA, 11 have comprehensive smoke-free statutes. Changes in the policy environment and in institutions such as unions, restaurant associations, and the tobacco industry since 2001 may improve the prospects for federal action and reduce disparities that currently characterize exposure to secondhand smoke.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
