Auscultation of foetal heart rate: an assessment of its error and significance.

AUSCULTATION OF FOETAL HEART RATE WAS SHOWN TO BE SUBJECT TO THREE TYPES OF ERROR: a random error, an error biased towards normality when the heart rate is fast or slow, and an error based on the inability to count the heart rate during contractions. In spite of these limitations a clinically observed foetal heart rate of more than 160 beats per minute was shown to be associated with significantly lower Apgar scores at birth. In contrast, a steady foetal heart rate of 100-120 beats per minute was not.

Practical issues in survey sampling.

This discussion reviews the principles of survey sampling and applies these principles in a study examining nurses' skills (N = 15,540). Three major facets of sampling are outlined-the sample frame, the sample size and the specific design of the selection procedures. The characteristics of a sample frame, precision in sample size estimation, and rules to be used in the selection procedures, are outlined. In addition, the authors recommend how to obtain assistance with these complex procedures and some steps in problem-solving. This paper provides guidance that will enable nurse researchers, using survey methods, to obtain sample estimates that closely resemble the population.
