Title: [abstract] DOPPLER ANALYSIS OF SPORT DIVER PROFILES.
Author: Dunford, RG; Wachholz, C; Fabus, S; Huggins, C; Mitchell, P; Bennett, PB
Abstract: Doppler scores for 81 male and 41 female divers were obtained following 640 recreational exposures during 14 DAN sponsored dive trips to warm water locations. Age (X = 39 years), depth (X = 72 fsw) and ratio of dives were similar for both sexes. Doppler measurement was carried out using the 0-4 Spencer scale at the precordial site with an IAPM Doppler 30 minutes post dive. A Doppler score >0 was observed in 46 divers following 89 exposures (145 scores were eliminated as unusable). A Doppler score = 3 occurred following 21 exposures but no score = 4 or case of decompression sickness were observed. Since the number of positive scores was small the data was dichotomized for Doppler score (+/-) , age (<40 vs >=40) and depth (<80 vs >=80 fsw). A repeated measure logistic regression model estimated relative odds for risk of + score. Males were more likely to produce + scores at fsw >=80 for both age groups (p<0.001). Females showed an increased risk for positive score only when age >=40 and fsw >= 80 (p=0.001). Dichotomized age at 35 and 45 years or depth at 70 and 90 fsw showed similar patterns. The first dive day showed less risk of + score when compared to the remaining days (p=0.04). Neither repetitive diving nor the use of a dive computer increased the risk of a + score.
