analyzed data because it is influenced by very large and very small
values within the sample and it would be prudent to consider the
median RT to be 11 min, since statistically the median is the middle
of the data set [56]. From this point of view, according to the
literature, the RT of Southwest Paraná SAMU is equivalent to the
average RT of European EMS. (rt = response time)

Using descriptive statistics, a mean RT of 14 min 25 s was identified,
with a median of 11 min and mode of 9 min. The average dispatch time
for ambulances was less than 5 min, with 3 min being the most frequent
