Understanding the basics of Lab tutor and power Lab

Make sure the PowerLab is connected and turned on. Place the pressure pad of the finger pulse transducer against the distal segment (the tip) of the middle finger or thumb of either hand. Use the Velcro strap to attach it firmly - neither loose nor tight.

Note that the number of pulses is inversely ______ to time intervals. Increasing in number of pulses lead to decrease in time interval and vice versa.

Record The number of ______ by selecting 10 seconds from the ______ and then count the number of ______ (peaks) in this 10 second and multiply by 10 to get the number of ______ per each minute.

Blood pressure can be raised by constriction and lowered by ______ of the arterioles

The resting pulse pressure in healthy adults, sitting position, is about ______ mmHg

The pulse pressure can be simply calculated from the difference of the measured ______ and ______ pressures

If your resting blood pressure is 120/80 millimeters of mercury (mm Hg), your pulse pressure is ______
