Hydrostatic weighing at residual volume and functional residual capacity.
Hydrostatic weighing (HW) was performed at both residual volume (RV) and functional residual capacity (FRC) to determine if underwater weighing at different lung volumes affected the measurement of body density. Subjects were 43 males, 18-25 yr. Subjects were submerged in the prone position, and the lung volume was measured by helium dilution at the time of the underwater weighing. Underwater w...
متن کاملComparison of the effect of Nutrition in Kangaroo Mother Care and Supine Positions on Gavage Residual Volume in Preterm Infants
Background: Feeding intolerance is a major concern in preterm infants. Appropriate position during feeding is one of the interventions that nurses can exploite in order to improve the feeding tolerance in preterm infants. Aim: Comparison of the effect of nutrition in the kangaroo mother care and supine position on gavage residual volume in preterm infants. Methods: Thisrandomized single-blind c...
متن کاملReference Values for Residual Volume, Functional Residual Capacity and Total Lung Capacity
Reference values play an important role in establishing whether, in an individual, measured volumes fall within a range to be expected for a healthy person of the same sex, similar stature, age, and other characteristics. Hence, reference values should be chosen that are appropriate to the person being investigated. Ideally, the reference values should be consistent; in the context of this pape...
متن کاملDifference between functional residual capacity and elastic equilibrium volume in patients with chronic obstructive pulmonary disease.
BACKGROUND A study was performed to determine the elastic equilibrium volume (Vr) of the respiratory system in patients with chronic obstructive pulmonary disease (COPD). METHODS Voluntary relaxed expiration from total lung capacity (TLC) was studied in three groups of subjects: seven patients with severe chronic airways obstruction (COPD), 10 normal subjects, and 15 subjects with restrictive...
متن کاملMeasuring tidal volume and functional residual capacity change in sleeping infants using a volume displacement plethysmograph.
The noninvasive measurement of infant lung function during unsedated sleep in infants has been a long-standing objective in paediatric respiratory medicine. This note reports on the design and performance of a head-out volume-displacement plethysmograph (VDP) that overcomes some of the limitations of traditional lung function apparatus. The VDP comprises a rigid acrylic box with an integral wat...
