A 2008 Cochrane review of smoking cessation activities in work-places concluded that "interventions directed towards individual smokers increase the likelihood of quitting smoking". [119] A 2010 systematic review determined that worksite incentives and competitions needed to be combined with additional interventions to produce significant ...
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.
It is a marker of respiratory muscle function and strength, [4] represented by cmH 2 O and measured with a manometer. MIP is an important and noninvasive index of diaphragm strength and an independent tool for diagnosing many illnesses. [5] Typical MIPs in adult males can be estimated from the equation M IP = 142 - (1.03 x Age) cmH 2 O, where ...
Lung volumes. Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. [1] At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles.
These changes ultimately result in an increased exchange of oxygen and carbon dioxide, which is accompanied by an increase in metabolism. [2] Respiratory adaptation is a physiological determinant of peak endurance performance, and in elite athletes, the pulmonary system is often a limiting factor to exercise under certain conditions.
The efficacy for each of the formulations alone (lozenges, nasal spray, gum, and transdermal patch) to aid in smoking cessation is equal. [27] Efficacy increases 15% to 36% with combining treatments such as gum and lozenges. Higher doses increase the chance of stopping smoking for a period of six months and more.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
