Congestive heart failure affects about 1 percent of adults in the United States1 and is a
contributing factor in over 250,000 deaths annually. 2 It is diagnosed in 400,000 Americans …

Lung ventilation is a mechanical process in which the respiratory muscles are acting in
concert to remove air in and out of the lungs. Any alteration in the performance of the …

Background—In congestive heart failure (CHF), the prognostic significance of impaired
respiratory muscle strength has not been established. Methods and Results—Maximal …

A variety of methods for subject selection and test procedures have been used for the
determination of normal values and reference equations for maximal inspiratory pressure …

The purpose of this study was to assess whether obesity induces changes in breathing
pattern and ventilatory neural drive and mechanics. Measurements performed in 34 male …

BACKGROUND: Respiratory muscle strength is an important part of lung function.
Assessment of the respiratory muscles' ability to generate force is important for recognizing …

Inspiratory function is essential for alveolar ventilation and expulsive behaviors that promote
airway clearance (eg, coughing and sneezing). Current evidence demonstrates that …

Lung diffusing capacity (D l) for carbon monoxide (D lco), nitric oxide (D lno) or oxygen (D lo
2) increases from rest to peak exercise without reaching an upper limit; this recruitment …

Aims The purpose of this study was to evaluate the effectiveness, feasibility, and safety of a 4‐
week high‐intensity inspiratory muscle training (hi‐IMT) in patients with chronic heart failure …

Reduced respiratory muscle strength has been reported in chronic heart failure (CHF) in
several studies. The data supporting this conclusion come almost exclusively from static …
