ABSTRACT:
Non invasive measurement of infant lung function during unsedated sleep is achieved by a plethysmograph which comprises of a rigid acrylic box (10) with integral water sealed spirometer (11) and a vacuum-actuated neck seal (20) allowing "head out" monitoring. The neck seal comprises particulate material entrapped in the space between two layers of rubber, which become rigid when a vacuum is applied to the space. Tidal volume, respiratory rate and changes in functional residual capacity (FRC) are able to be recorded during unsedated REM and NREM sleep whilst monitoring with conventional polysomnographic methods. The head out configuration allows additional instrumentation to be used, avoids facial stimulation and allows unimpeded access to the upper airway.
