Measuring 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...
متن کاملCalibration of respiratory inductance plethysmograph in preterm infants with different respiratory conditions.
Respiratory inductance plethysmography (RIP) is a method for respiratory measurements particularly attractive in infants because it is noninvasive and it does not interfere with the airway. RIP calibration remains controversial in neonates, and is particularly difficult in infants with thoraco-abdominal asynchrony or with ventilatory assist. The objective of this study was to evaluate a new RIP...
متن کاملMeasurement of tidal breath by determination of chest wall volume displacement in patients with airflow obstruction.
We compared tidal volume (VT) measured from the integrated airflow signal of a pneumotachygraph (PNTG) in ten patients, seated comfortably, with airway obstruction to VT, recorded simultaneously, by three chest-wall volume-displacement methods: two-channel magnetometer, isovolume calibration (mag-isov); respiratory inductance plethysmograph, isovolume calibration (rip-isov); and, inductance ple...
متن کاملContinuous Non-Invasive Monitoring of Tidal Volumes by Measurement of Tidal Impedance in Neonatal Piglets
BACKGROUND Electrical Impedance measurements can be used to estimate the content of intra-thoracic air and thereby give information on pulmonary ventilation. Conventional Impedance measurements mainly indicate relative changes, but no information concerning air-volume is given. The study was performed to test whether a 3-point-calibration with known tidal volumes (VT) during conventional mechan...
متن کاملCT measurement of the normal ventricular system in premature infants.
In order to develop quantitative criteria for normal lateral ventricular dimensions, 70 cerebral computed tomographic scans of premature infants were reviewed and 31 normal scans were selected as suitable for establishing cerebroventricular indices. In 15 normal premature infants of less than 32 weeks gestational age the mean bifrontal index was 0.28 +/- 0.05, the mean bicaudate index 0.10 +/- ...
