Coughing:
12. Click Collect to begin data collection. There will be a 15 s delay while data are collected
before the first point is plotted on the upper graph. Thereafter, a point will be plotted
every 5 s. Obtain approximately 45 s of graphed data as a baseline heart rate.
13. Begin data collection by pressing start.
a. At approximately 60 s, begin to cough continuously (every 1–3 s). The heart rate will
change in response to the coughing. When the heart rate levels off for at least 15 s (or
reverses direction), stop coughing. Data will be collected for at least 200 s.
14. Determine the baseline heart rate.
a. Tap and drag over the area of the graph where the baseline heart rate is displayed to
select the data.
b. Choose Statistics from the Analyze menu.
c. Record the mean baseline heart rate, to the nearest whole number, in Table 2.
d. Choose Statistics from the Analyze menu to turn off statistics.
15. Determine the maximum heart rate.
a. Tap and drag over the region where the heart rate levels off.
b. Choose Statistics from the Analyze menu.
c. Record the mean heart rate to the nearest whole number as the Maximum heart rate
in Table 2.
d. Choose Statistics from the Analyze menu to turn off statistics.
16. Determine the difference between the Maximum heart rate and the Baseline heart rate
and record this value in Table 2.
17. Determine the time between the onset of coughing and the beginning of the plateau.
a. Tap the data point at approximately 60 s that represents the time at the onset of
coughing and note the time component of this point.
b. Tap the point at the beginning of the plateau and note the time component of this
point.
18. Determine the difference between the two time values and record this value as the
response time in Table 2.
19. Determine the recovery time.
a. Tap the last data point on the plateau and note the time component of this point.
