Functional 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 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 کاملCephalometric Measurements in Infants with Congenital Heart Disease Compared to Healthy Infants
Introduction: The lack of adequate blood perfusion through different organs of the body, including the brain and skull, can be caused by any type of circulation abnormality. The purpose of this study is to compare cephalometric indices between infants under the age of 12 months who have congenital heart disease (CHD) and normal infants. Materials and Methods: This case-control study was ca...
متن کاملThoracic gas volume at functional residual capacity measured with an integrated-flow plethysmograph in infants and young children.
Thoracic gas volume (TGV) was measured with an integrated flow plethysmograph in 15 infants aged 2-34 months. End-expiratory (TGVe) and end-inspiratory (TGVi) airway occlusions were compared, after correction of TGV for the occluded volume above functional residual capacity (FRC). The relationship between pressure at the airway opening (Pao) and volume displaced from the box during airway occlu...
متن کاملMeasurement of lung volume and ventilation distribution with an ultrasonic flow meter in healthy infants.
Small airway disease in infants is characterised by abnormal lung volume and uneven ventilation distribution. An inert tracer gas washin/washout technique using a pulsed ultrasonic flow meter is presented to measure functional residual capacity (FRC) and ventilation distribution in spontaneously breathing and unsedated infants. With a pulsed ultrasound sent through the main stream of the flow m...
