Disposable pressure transducers.

We evaluated 12 disposable pressure transducers from 11 manufacturers. All are rated Acceptable and are ranked in four groups. The first two groups have similar performance characteristics. Groups three and four are ranked primarily according to the effect of fluid spills and the ease of achieving accurate dynamic response. Although list prices are somewhat high, negotiated prices are usually lower. Users should weigh advantages and disadvantages against clinical preference and price.
