Validation of respiratory inductive plethysmography using the Qualitative Diagnostic Calibration method in anaesthetized infants.
The aim of this study was to compare tidal volume (VT) derived from the Qualitative Diagnostic Calibration (QDC) method (VT,QDC) with measurements from pneumotachography (VT,PN,T) in anaesthetized infants. Measurements were made during spontaneous (SV) and intermittent positive pressure (IPPV) ventilation, sighs and airway occlusions. The VT,DIF was the difference between VT,QDC and VT,PNT (%VT...
متن کاملMathematical assessment of qualitative diagnostic calibration for respiratory inductive plethysmography.
We present a critical assessment of qualitative diagnostic calibration (QDC), which claims to provide a relative calibration of respiratory inductive plethysmography during natural breathing (Sackner MA, Watson H, Belsito AS, Feinerman D, Suarez M, Gonzalez G, Bizousky F, and Krieger B. J Appl Physiol 66: 410-420, 1989). QDC computes the calibration factor (K) by considering breaths of constant...
متن کاملChest wall motion in preterm infants using respiratory inductive plethysmography.
Preterm infant tidal breathing may be different from that of healthy full-term infants because of various features of the premature thorax. The purpose of this project was to describe chest wall motion in the preterm infant (gestational age <37 weeks) and compare it with chest wall motion data in a group of healthy, full-term infants. We wanted to use an objective bedside method for assessment ...
متن کاملValidation of respiratory inductive plethysmography in patients with pulmonary disease.
The assumption that the respiratory system behaves with 2 df of motion in healthy persons allows calibration of respiratory inductive plethysmography (RIP) with spirometry (SP). To ascertain whether RIP could be calibrated by the same assumption in patients with lung disease, even though at least 3 df of motion are visualized (ie, upper and lower rib cage and upper and lower abdomen move out of...
متن کاملRespiratory monitoring by inductive plethysmography in unrestrained subjects using position sensor-adjusted calibration.
BACKGROUND Portable respiratory inductive plethysmography (RIP) is promising for noninvasive monitoring of breathing patterns in unrestrained subjects. However, its use has been hampered by requiring recalibration after changes in body position. OBJECTIVES To facilitate RIP application in unrestrained subjects, we developed a technique for adjustment of RIP calibration using position sensor f...
