Abstract Background Pulmonary function tests (PFTs) are routinely performed in the upright
position due to measurement devices and patient comfort. This systematic review …

Chronic heart failure (HF) is a complex multiorgan syndrome characterized by
pathophysiological changes in cardiac, vascular, musculoskeletal, endocrine, and …

Aims We have often found that patients with heart failure had shortness of breath when
bending forward. The frequency of bendopnea in patients with decompensated heart failure …

Aim The purpose of this study was to compare lung ultrasound findings in both the supine
and upright positions in heart failure patients presenting with dyspnea or chest pain …

Early mobilization has become an important aspect of treatment in intensive care medicine,
especially in patients with acute pulmonary dysfunction. As its effects on regional lung …

The lungs are the primary organs affected in LHD (left heart disease). Increased left atrial
pressure leads to pulmonary alveolar–capillary stress failure, resulting in cycles of alveolar …

Background: Body positioning is prescribed to optimize cardiopulmonary functions.
Positioning helps to improve lung function and oxygen saturation in patients who are …

We determined whether a non-invasive gas exchange based estimate of pulmonary
vascular (PV) capacitance [PVCAP= stroke volume (SV) x pulmonary arterial pressure …

Rationale Sitting-to-supine fall in vital capacity (ΔVC) can be used to help identify diaphragm
dysfunction (DD), but its optimal predictive threshold value is uncertain. Our aim was to …

No clinical studies to date have compared the airway luminal area between supine and
standing positions. Our aim was therefore to compare the airway luminal area between …
