The conceptual overview, along with the experimental procedures are found in the NPB 101L Physiology Lab Manual 2nd Edition. More specifically, pages 55 to 63 provided a full insight to all the experiments in the respiratory lab. In addition, a list of required materials was given for every experiment. The authors of this lab manual were Erwin Bautista and Julia Korber. As for data acquisition, the BIOPAC software was used to collect and record data for all the trials. Furthermore, the teaching assistants had calibrated each station prior to initiating the lab exercises. For the entirety of the respiratory lab, a human subject was used in all the experiments. A 22-year-old female was the participant for the first two experiments regarding …show more content…

The same method was utilized to find expiratory reserve volume. Except, the I-beam cursor was dragged in-between the trough of a normal and maximum exhalation. As for tidal volume, it was discovered using the absolute value between the peak and the trough of a normal wave. The last data to be found using the BIOPAC was the subject’s vital capacity. Here, the I-beam cursor was dragged from the peak of the maximum inhalation to the trough of maximum exhalation. Other vital information that can be extracted from the BIOPAC software was the respiratory rate of the subject. Counting every wave peak for the last 30 seconds and multiplying the value by 2 yielded the respiratory rate. Having these information, minute ventilation can now be calculated by multiplying respiratory rate with tidal wave volume. This led to the calculation of alveolar ventilation since the formula is minute ventilation minus dead space volume. In order to find out the subject’s dead space volume, her weight was multiplied with the respiratory rate. Moving on to Part 2 of the respiratory lab, the experiment was designed to observe the difference between length of breath-hold and ventilation type. These ventilation types consist of normal breathing, re-breathing, and hyperventilating. The second component to part 2 was to see a correlation between the
