Beer's Law & Anesthesia Lab
Headline: Aunt Elda's Dead!
Yes, my experience with anesthesia was that I had local anesthesia on my left hip last year in order for fluid to be drawn out of the joint and tested for infection. Luckily, there wasn't one!
2) What characteristics of anesthesia are desirable?
Characteristics of anesthesia that are desirable include less than 40% concentration, blocks nerve cells, and that the patient doesn't remember the surgery (only general anesthesia).
3) What characteristics of anesthesia are not desirable?
Characteristics of anesthesia that are not desirable include above 40% concentration and that the patient doesn't wake up after the surgery (only general anesthesia).
Logger Pro (installed on computer)
8 Graduated Cylinders
IMPORTANT: When using graduated cylinders, ALWAYS read measurements from the bottom of the meniscus.
Fill the various cuvettes about 3/4 of the way with the solution of concentrations 0%, 10%, 20%, 30%, 40%, 50%, and 100%. Then make another with a mystery concentration and label this "Aunt Elda".
Plug in the calorimeter via USB and start up the program Logger Pro. Make sure the calorimeter is turned on and is being registered by the computer program.
Make sure the green light is lit below the 635mm. If not, use the arrows to scroll over. Next calibrate it by inserting the 0% concentration into the calorimeter and press 'CAL'. Now it's time to start the experiment!
2) Click Keep. In the pop-up box, label it 0%. (Or what ever percentage you are on)
3) The data should be recorded in the program. Remove the cuvette from the calorimeter and dumb the contents down the drain.
4) Insert the next cuvette and repeat steps 2-4.
- Label Aunt Elda's Sample as "?"
5) Press Stop after collecting all the data,
6) To make a line of best fit, press the f(x) key. Pick the best regression model that fits the plotted points.
7) Use the interpolate feature found in the "analyze data" menu to help find the concentration of Aunt Elda's sample.
Yes, the concentration of Aunt Elda's anesthesia was too strong. It was over 40%, which is lethal.
2) If yes, how did that cause her death? If no, do you have a hypothesis for the cause of her death?
The anesthesia caused her death in that she never woke up from the surgery since the concentration was over 40%.
3) How did Beer's Law help you solve this case?
Beer's Law helped us solve the case by using the graph. We were able to determine the point of concentration of her anesthesia.
