BACKGROUND The clinical practice of pediatric anesthesiology has changed with increasing use of cuffed endotracheal tubes (cETTs) in infants and children. To limit the risk of tracheal mucosal damage, regular monitoring of intracuff pressure (CP) is necessary. This study evaluates the efficacy and accuracy of a novel syringe device that provides a digital readout of the CP. METHODS The study ...

(The diagram gives, however, no indication of the hydrostatic pressure due to the liquid in the manometer tube, which is a necessary condition for equilibrium. For further details of the experiments Loeb's original papers and book s may be consulted.) AH and BH represent hydrogen electrodes; AK and BK, calomel electrodes connected to the solutions by saturated KC1. Loeb measured the potential d...

Measurements of the spatial distribution of the time-averaged second-order pressure in a plane standing wave in atmospheric air are reported. Several measurement pitfalls are identified, and solutions are described. These include accounting for slight nonlinearity of the piezoresistive transducer and careful mounting of the transducer. Streaming causes extra complication when a capillary-connec...

The article gives the electrical conductivity of whole and shredded plant tissue. An experimental study was made dependence resistivity value volume occupied by pulp on pressing time specific pressures while taking into account amount pressed juice. resistance (R) crushed tissue experimentally studied, which, when processing results, recalculated to (ρ) pressure (P) determined using a reference...
