Assignment task: Can I get help creating graphs and explanations for these two questions please.
Sarah was recently diagnosed with an obstructive lung disorder. In their diagnostic process the doctors completed a Forced Vital Capacity test on Sarah to determine her lung function. Based on this, (A) diagram a Vital Capacity test with lung volumes for a healthy individual and on the same graph include the VC test with lung volumes for Sarah's diagnosis. The doctors also found that Sarah's oxygen saturation was at 85%. Therefore, (B) diagram an oxygen saturation curve graph that shows a normal oxygen saturation curve vs. a curve representing Sarah's condition. Also list out the factors that can impact oxygen saturation for Sarah.
Ashor has been putting himself through a strict diet and exercise regiment. In the last week, he was feeling some irregularity in his heart rate and heart beat. He decided to visit a doctor and found that he was suffering from Hyperkalemia through an ECG and blood tests. The ECG had an extremely peaked T wave, widened QRS, short QT interval, and ST segment depression. Please diagram the ECG the doctor would have seen with hyperkalemia. Also use a diagram to explain how Hyperkalemia impacts cardiac pacemaker and contractile cells - focus on the pacemaker and contractile potentials - do not diagram something you don't understand. The key here is to consider resting membrane potentials and how that impacts slow and fast acting ion channels in the cardiac conduction process. Make sure to include the following items at a minimum in the conduction diagram(s):
- mV (Membrane Potential in millivolts)
- Na+
- K+
- Ca+
- Slow acting channels
- Fast acting channels
- -40mV
- -60mV
- -90mV
- Pacemaker potential
- Depolarization
- Repolarization
- Hyperpolarization
- Absolute Refractory Period
