Background Severe obesity causes respiratory morbidity and mortality. The impact of obesity
on the mechanics of breathing is not fully understood. Patients and methods We undertook a …

In obese people, the presence of adipose tissue around the rib cage and abdomen and in
the visceral cavity loads the chest wall and reduces functional residual capacity (FRC). The …

Objective: Our objective was to study the effects of extreme obesity on pulmonary function
tests and the effects of smoking on these variables in a population group larger than has …

Obesity has long been recognized as having significant effects on respiratory function. The
topic has been studied for at least the last half century, and some clear patterns have …

More or Less? 0 besity is one of the most frequently found markers of health risk in the
United States. Over one-third of adults are at least 20% over ideal weight, and the …

To explore mechanisms of restrictive respiratory physiology and high pleural pressure (PPl)
in severe obesity, we studied 51 obese subjects (body mass index= 38–80.7 kg/m2) and 10 …

Introduction Obesity can cause hypoxemia by decreasing lung volumes to where there is
closure of lung units during normal breathing. Studies describing this phenomenon are …

Obesity, because it alters the relationship between the lungs, chest wall, and diaphragm,
has been expected to alter respiratory function. We studied 43 massively obese but …

Background Obesity is a major health issue in North America, and the trend is for obesity to
be a more important medical issue in the future. Since obesity can cause respiratory …

The major respiratory complications of obesity include a heightened demand for ventilation,
elevated work of breathing, respiratory muscle inefficiency and diminished respiratory …
