Sentence examples for mean compression rate from inspiring English sources

There were significant differences between the control and flashlight groups in mean compression rate (MCR), MCR/min and visual analogue scale.

We measured the mean compression rate, compression depth, "duty cycle" and the percentage of compressions completely released using the Laerdal PC Skill Reporting System (Version 2.4.1, Laerdal Medical GmbH).

4 6 Oh et al found that metronome use increased the mean compression rate (MCR) to the desired value, but compression depth decreased because of the requirement to multitask (CPR technique and audio perception of audio tones).

During all available minutes of data (table 2), cases randomised to feedback-on compared with feedback-off had significantly lower mean compression rate (103 v 108 per minute, P<0.001), higher chest compression fraction (66% v 64%, P=0.016), deeper chest compressions (40 v 38 mm, P=0.005), and fewer chest compressions with incomplete release (10% v 15%, P<0.001).

Based on previous research that reported a standard deviation of 20.93 for a paired difference in mean compression rates, 16 we estimated that we needed 140 participants to detect a mean paired difference between any two interventions of five compressions per minute with a power of 0.80 and an α of 0.05.

We determined the differences between interventions in average compression rates, the proportion of participants performing compressions at the correct rate, the proportion of correct compressions and the causes of errors, correlations between the rate of compressions and the proportion delivered at the correct depth, and relative risk and numbers needed to treat for correct compression rate.

Our primary outcome measure was the paired differences in average compression rates between interventions.

The mean chest compression rate increased significantly in the v-CPR group as compared with t-CPR (110 ± 16 vs. 86 ± 28; P < 0.0001), while depth remained constant (48 ± 13 mm vs. 47 ± 16 mm, P = NS).

The last item means sound compression rate and monophonic sound or stereophonic sounds.

3 Audio-prompt rate guidance significantly improves chest compression rate and mean end-tidal CO2 concentration during CPR.

As the number of occupied sub-bands decreases, the optimal compression rate can be reduced, which means a lower sampling ratio is needed.
