The Body-Mass Index, Airflow Obstruction, Dyspnea, and Exercise Capacity Index in Chronic Obstructive Pulmonary Disease

New England Journal of Medicine, 2004
Chronic obstructive pulmonary disease (COPD) is characterized by an incompletely reversible limitation in airflow. A physiological variable--the forced expiratory volume in one second (FEV1)--is often used to grade the severity of COPD. However, patients with COPD have systemic manifestations that are not reflected by the FEV1.

Nasal congestion index: A measure for nasal obstruction

Laryngoscope, 2009
AbstractObjectives:The relationship between congestion of the nasal mucosa and subjective nasal obstruction remains poorly defined. Applying the novel Nasal Congestion Index (NCI), we compared subjective nasal obstruction with objective measures for reversible congestion of the nasal mucosa.Study Design:A total of 2,523 consecutive patients were ...

Obstructive Sleep Apnea and Cardiac Index

Chest, 1986
Seventeen men (age range, 21 to 58 years) with severe obstructive sleep apnea syndrome (OSAS) documented by nocturnal polysomnography underwent hemodynamic investigations during sleep. We studied the evolution of the cardiac index during apneic events in both NREM and REM sleep using the thermodilution technique.

Choroidal vascularity index in obstructive sleep apnea syndrome

Sleep and Breathing, 2021
There is growing evidence supporting an association between obstructive sleep apnea syndrome (OSAS) and systemic vascular disorders. However, the data on choroidal microvasculature are limited. In recent years, choroidal thickness (CT) and choroidal vascularity index (CVI) have been of considerable interest as objective markers of choroidal vascularity.

The obstructive index in antenatal unilateral pelviureteric junction obstruction: A novel predictor of the failure of conservative management

Pediatrics International, 2022
AbstractBackgroundTo find the impact of the obstructive index (OI) as a predictor of management in antenatal pelviureteric junction obstruction.MethodsRecords of 135 cases of antenatally detected unilateral pelviureteric junction obstruction, selected for initial observation were retrospectively analyzed.

A Proposed Curvilinearity Index for Quantifying Airflow Obstruction

Respiratory Care, 2005
Though forced expiratory volume in the first second (FEV(1)) is the primary indicator of airway obstruction, curvilinearity in the expiratory flow-volume curve is used to support the quantitative assessment of obstruction via FEV(1). Currently there is no available index to quantify a pathological contour of curvilinearity.We propose a "curvature ...

Partial ureteral obstruction: role of renal resistive index in stages of obstruction and release

Urology, 1997
To study the changes in renal resistive index (RI) and renal function before and after release of different grades of partial unilateral ureteral obstructions.Ten dogs were subjected to right partial ureteral obstruction. Grade 1 (mild) obstruction was applied to 5 dogs (group A) and grade 3 (moderate and severe) obstruction was applied to the other 5 ...
