If you are having problems collecting data for this experiment when using LabQuest as a standalone device, make sure you are using the LabQuest-specific instructions for the lab activity. The LabQuest instructions for this activity can be found on the CD, located in the back of Human Physiology with Vernier (HP-A) or through the electronic resources available from your web account. See How do I access my lab books from my account on the Vernier website?

If you are recording Heart Rate data and Blood Pressure data on LabQuest using Channel 1 for Blood Pressure and Channel 2 for Heart Rate, then you may be following the computer instructions instead of the LabQuest-specific instructions. The computer instructions will not work for this activity when using the LabQuest App.
