Functional residual capacity during anaesthesia. II. Spontaneous respiration.
Functional residual capacity has been measured by helium dilution in 26 spontaneously breathing patients before and immediately after anaesthesia, which was induced with thiopentone and maintained with halothane. The mean reduction was 390 ml (16.1% or pre-induction value) and the change was highly significant (P less than 0.001). The decrease in FRC correlated with age (r equals 0.41: P less t...
متن کاملRelationship between functional residual capacity, respiratory compliance, and oxygenation in patients ventilated after cardiac surgery.
BACKGROUND Measurement of functional residual capacity (FRC) is now possible at bedside, during mechanical ventilation. OBJECTIVES To determine the relationship of measured absolute and relative predicted FRC values to oxygenation and respiratory-system compliance, and to identify variables that influence FRC in ventilated patients after cardiac surgery. METHODS We retrospectively analyzed ...
متن کاملHydrostatic 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 کاملFunctional residual capacity in healthy preschool children.
The purpose of this study was to evaluate the feasibility of routine functional residual capacity (FRC) measurements in healthy preschool children aged 2.7-6.4 yrs. Furthermore, accuracy and reproducibility were investigated and normal values were collected. A mass-produced closed-circuit helium dilution device (rolling seal) was used. Selection of the 113 healthy children (from the 571 measure...
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...
