Slow vital capacity : differences between expiratory and inspiratory vital capacities

Respiratory function technologists/scient., 2019
Introduction: Vital capacity (VC) can be determined through expiratory (EVC) or inspiratory maneuvers (IVC). It is fundamental for determination of lung volumes and its incomplete mobilization has repercussions on the detection of air trapping or pulmonary hyperinflation.

[Dyspnea and inspiratory effort capacity in COPD].

Revue des maladies respiratoires, 1994
The aim of this work was to study the relationship between dynamic hyperinflation and dyspnoea perception on exercise in patients with chronic obstructive pulmonary disease (COPD). Seven men and three women with COPD (mean FEV1 45.9 +/- 9.8% predicted) were studied.

Inspiratory Capacity Through the Turbuhaler in Various Patient Groups

Journal of Aerosol Medicine, 1994
The effect of the Turbuhaler depends upon the inspiratory flow rate generated by the patient during the inhalation. In children both the peak inspiratory flow rate and the volume of air inhaled at that inspiratory flow rate are important. An inspiratory flow rate greater than 30L/min is usually considered sufficient to achieve an optimal effect. The

Estimation of inspiratory capacity in health and in subjects with respiratory muscle paralysis

Journal of Applied Physiology, 1959
A method is described for the reproduction of the natural inspiratory capacity in healthy subjects utilizing a pressure breathing device capable of delivering high inflow rates at low pressures (1.3 l/sec. at 5 cm of water in the delivery system). A highly significant correlation was found between natural inspiratory capacity and the estimation of ...

Clinimetric properties of breath‐stacking technique for assessment of inspiratory capacity

Physiotherapy Research International, 2011
AbstractBackground and PurposeBreath stacking (BS) is used as an alternative method for lung expansion therapy and the assessment of inspiratory capacity in uncooperative patients. The aims of the present study were to identify the reproducibility of the BS technique in healthy volunteers and to compare BS with conventional spirometry with regard to ...

Inspiratory muscle training fails to improve endurance capacity in athletes

Medicine & Science in Sports & Exercise, 2002
The purpose of this study was to examine the effects of specific inspiratory muscle training (IMT) on respiratory muscle strength and endurance and whole-body endurance exercise capacity in competitive endurance athletes.Seven collegiate distance runners (5 male/2 female; VO2max = 59.9 +/- 11.7 mL.kg-1.min-1) were recruited to participate in this study.

Determinants of the first inspiratory volume and functional residual capacity at birth

Pediatric Pulmonology, 1986
AbstractWe have investigated the pattern of pressure and volume changes that occur in vaginally delivered, full‐term infants during the onset of spontaneous respiration. Within a few seconds of delivery of the head, simultaneous measurements were made of stomach and esophageal pressure changes together with volume changes determined at the mouth ...

Forced Vital Capacity, Slow Vital Capacity, or Inspiratory Vital Capacity: Which Is the Best Measure of Vital Capacity?

Journal of Asthma, 1998
Vital capacity can be measured as forced vital capacity (FVC), slow vital capacity (SVC), and inspiratory vital capacity (IVC). Although it is well known that the latter two are generally greater, a systematic comparison of the three in subjects with different degrees of airways obstruction has not been made.

[Measurement of maximal inspiratory flow and forced inspiratory capacity and its clinical application].

Hua xi yi ke da xue xue bao = Journal of West China University of Medical Sciences = Huaxi yike daxue xuebao, 1997
The methods of measuring the maximal inspiratory flow (V(imax)) and the forced inspiratory capacity (FIC) via forced inspiratory capacity-time curve (FIC-t curve) were investigated. Both V(imax) and FIC were measured in 35 normal subjects and 89 patients with chronic obstructive pulmonary disease (COPD).
