RESP Pre-Lab Assignment

Use the RESPIRATORY manual attached and answer all the questions  in this worksheet typing your answers after "your answer". 

Your answers should be numbered, typed, in your own words.

Find all of the information necessary to complete this assignment in the textbook, lecture resources, and/or your laboratory manual.  Outside trusted sources may also be used (use .org, .ed, .gov)

If you want to cite your sources, use APA citations of each source within the text and in a list at the end.  

For questions (1), (3), and (4) pretend that you are meeting a friend for coffee before your laboratory session, and your friend wants to know what you will be doing during lab.  Your friend has not taken any science classes.

(1) What is your team’s hypothesis?  For this RESP experiment, add a second sentence to help your friend understand your team’s volume or capacity.

      Your answer: THE HYPOTHESIS IS " SMELLING ROSE WATER WILL INCREASE TIDAL VOLUME"

(2) How will the calibration be completed?   For this RESP experiment, your team will complete Stage 1 and Stage 2.

During Stage 1, which part(s) of the equipment are used and in which position?  How long is Stage 1? 

Your answer:

During Stage 2, in which order are the calibration syringe and filter connected to the transducer?  To which side of the transducer?  In which position does the calibration syringe start?  What do you do with the syringe during calibration?  How long is Stage 2? 

Your answer:

 (3) How will your subject be connected to the computer? 

For this RESP experiment, what is a transducer/spirometer in terms your friend can understand?  Which piece(s) of equipment from the calibration is/are not used when recording from your subject(s).  Which piece(s) of equipment are added?  In which order will the filter, mouthpiece, and nose clip be connected to the transducer and to which side of the transducer?

Your answer:

(4) What will your subject do during the experiment?  Pretend your subject just contacted you to let you know that they cannot make it to lab.  You ask your friend to be your subject and need to explain what her/she will be doing. 

In which position will your friend/subject be? 

Your answer:

Will your friend/subject be wearing anything such as headphones, sleep mask, earplugs, etc.? 

Your answer:

What is your stimulus, and how will your subject be exposed to stimulus?  (Example: We will hold a Q-tip with essential oil 1 centimeter from our subject’s nose.)

Your answer:

How will you control your experiment?  In other words, how will the conditions without stimulus be the same as with stimulus? (Example: We will hold a Q-tip with water 1 centimeter from our subject’s nose.)

Your answer:

How long will your subject be exposed to stimulus?  Will this alternate with no stimulus?  How many times?  (Example: We will expose our subject to water on a Q-tip for 1 minute then to essential oil on a Q-tip for 1 minute.  The subject will be exposed to water 3 times and to essential oil 3 times).

Your answer:

For this RESP experiment, how will your friend/subject need to breathe in order to measure your team’s volume or capacity?  (For example., will there be normal tidal breaths or will he/she need to complete a maximal inhale and/or exhale?)

Your answer:

For most experiments, you started the recording then exposed your subject to the controls and stimulus.  Will your team do this for the RESP experiment, or will you record before and after the stimulus?  Why?  What is the total length of time that you will record the RESP?  (Example: We will record for a total of 6 minutes.)

Your answer:

(5) How are waves analyzed?  During your experiment, you will be recording many waves, however, you only need to analyze ten (or more) waves. 

When you wrote your methods plan, which waves did your team decide to highlight? 

Your answer:

Why did your team decide to highlight these waves?

Your answer:

To analyze your team’s respiratory volume or capacity, where will you start highlighting and where will you end? 

Your answer:

Will you use delta or P-P and why?  (For instance, what is delta and what is P-P)?

Your answer:

(6) What is the relationship between what you will highlight and your team’s dependent variable? What will your team highlight (for example, where will you start and where will you end)?  How will what your team highlights relate to the volume or capacity your team is measuring?

Your answer:

(7) What is your rationale for your team’s RESP experiment?  For example, why do you think your team’s stimulus will result in your predicted change in volume or capacity?  Include some parts of a reflex-response loop.

Your answer:

(8) How does the CNS stimulate air movement into and out of the lungs?

Which division of efferent nervous system will stimulate contraction of respiratory muscles? 

Your answer:

Which type of muscles are these?  (Hint: what are the three types of muscle tissue?) 

Your answer:

Will this contraction increase or decrease lung volume? 

Your answer:

Will this change in lung volume to increase or decrease pressure? 

Your answer:

Will this cause inhalation or exhalation? 

Your answer:
