Functional 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 کاملImpact of depth of propofol anaesthesia on functional residual capacity and ventilation distribution in healthy preschool children.
BACKGROUND Propofol is commonly used in children undergoing diagnostic interventions under anaesthesia or deep sedation. Because hypoxaemia is the most common cause of critical deterioration during anaesthesia and sedation, improved understanding of the effects of anaesthetics on pulmonary function is essential. The aim of this study was to determine the effect of different levels of propofol a...
متن کامل[Comparative evaluation of healthy preschool children blink].
PURPOSE To evaluate spontaneous blink activity in the primary eye position in normal preschool children. METHODS Two hundred normal children aged 4 to 6 years were prospectively evaluated. They were digitally videotaped in a standard setting, taking the images on frontal and lateral plans, during the vigil state, in the primary eye position. The object of observation was located at the same l...
متن کاملFunctional residual capacity measurements in healthy infants: ultrasonic flow meter versus a mass spectrometer.
Accurate, reproducible and portable bedside monitoring of lung volume could potentially facilitate the early recognition of both under and overinflation of the lungs in ventilated and nonventilated subjects. This study asked whether a prototype portable ultrasonic flow meter provided valid and reliable measurements of functional residual capacity (FRCUS) when compared to those obtained using a ...
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...
