Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

21 notecards = 6 pages (4 cards per page)

Exercise 47: Acid-Base balance: Computer Simulation

front 1

ACTIVITY 1: NORMAL BREATHING

WHAT WAS THE pH LEVEL DURING NORMAL BREATHING?

back 1

BETWEEN 7.38 AND 7.42

front 2

ACTIVITY 1: NORMAL BREATHING

WAS THIS pH WITHIN THE NORMAL pH RANGE?

back 2

YES, THE pH (7.38 - 7.42) WAS WITHIN THE NORMAL pH RANGE OF 7.35 AND 7.45

front 3

ACTIVITY 2: HYPERVENTILATION

IN RUN 1, WHAT WAS THE MAXIMUM pH RECORDED WITH HYPERVENTILATION?

back 3

40

front 4

ACTIVITY 2: HYPERVENTILATION

WHAT ACID-BASE IMBALANCE OCCURRED WITH HYPERVENTILATION?

back 4

THE pH VALUE BEGAN TO EXCEED THE NORMAL RANGE BETWEEN 10 AND 20 SECONDS - AS SOON AS IT ROSE ABOVE 7.45, THIS INDICATED THE CONDITION OF ALKALOSIS.

front 5

ACTIVITY 2: HYPERVENTILATION

WHAT HAPPENED TO THE TIDAL VOLUME DURING HYPERVENTILATION?

back 5

IT WAS LARGER DURING HYPERVENTILATION

front 6

ACTIVITY 2: HYPERVENTILATION

DESCRIBE THE TRACE WHEN HYPERVENTILATION STOPPED IN RUN 2.

back 6

THE TRACE FLAT-LINED, INDICATING THE BREATHING WAS SUSPENDED. BREATHING DID NOT RETURN TO NORMAL, IMMEDIATELY THE BODY TEMPORARILY STOPPED BREATHING IN ORDER TO RESTORE PCO2 LEVELS TO NORMAL VALUES.

front 7

ACTIVITY 3: REBREATHING

WHAT WAS THE EFFECT ON pH OVER TIME WITH REBREATHING?

back 7

pH LEVELS OF BLOOD DECREASED OVER TIME WITH REBREATHING, AND pH LEVERS WEREN'T ALWAYS WITHIN NORMAL RANGE.

front 8

ACTIVITY 3: REBREATHING

DID REBREATHING RESULT IN ACIDOSIS OT ALKALOSIS? WHY? HINT: SPECIFICALLY RELATE THIS TO THE LEVEL OF CO2.

back 8

REBREATHING RESULTED IN ACIDOSIS BECAUSE THE pH VALUE BEGAN TO DIP BELOW THE NORMAL RANGE BETWEEN 20 AND 30 SECONDS - SOON AS IT WENT BELOW 7.35. ACIDOSIS IS THE RESULT OF IMPAIRED RESPIRATION (HYPOVENTILATION) THAT LEADS TO THE ACCUMULATION OF TOO MUCH CARBON DIOXIDE IN THE BLOOD.

front 9

ACTIVITY 3: REBREATHING

LOST SOME POTENTIAL CAUSES THAT WOULD MIMIC THE PATTERNS OF pH AND CO2 LEVERS SEEN IN THIS REBREATHING SIMULATION.

back 9

LUNG DISEASE, AIRWAY OBSTRUCTION, DEPRESSING OF RESPIRATORY CENTER IN BRAIN STEM, AND DRUG OVERDOSE.

front 10

ACTIVITY 4: RENAL RESPONSE TO NORMAL ACID-BASE BALANCE

DESCRIBE HOW THE pH OF THE BLOOD CHANGES WITH AN INCREASE IN THE LEVEL OF CO2.

back 10

AS CO2 INCREASES, pH VALUE DECREASED.

front 11

ACTIVITY 4: RENAL RESPONSE TO NORMAL ACID-BASE BALANCE

WHY DOES THIS CHANCE OCCUR?

back 11

BECAUSE CO2 LEVELS DIRECTLY AFFECT BLOOD pH LEVELS.

front 12

ACTIVITY 5: RENAL RESPONSE TO RESPIRATORY ALKALOSIS

WHAT HAPPENED TO THE LEVEL OF H+ IN THE URINE AS THE LEVEL OF CO2 DECREASED?

back 12

A DECREASED LEVEL OF H+ WAS PRESENT IN THE URINE

front 13

ACTIVITY 5: RENAL RESPONSE TO RESPIRATORY ALKALOSIS

EXPLAIN HOW THE RENAL SYSTEM COMPENSATES FOR RESPIRATORY ALKALOSIS.

back 13

RENAL SYSTEM COMPENSATED FOR RESPIRATORY ALKALOSIS BY INCREASING PCO2 LEVELS AND DECREASING pH LEVELS.

front 14

ACTIVITY 5: RENAL RESPONSE TO RESPIRATORY ALKALOSIS

WHICH TYPE OF BREATHING RESULTS IN RESPIRATORY ALKALOSIS?

back 14

HYPERVENTILATION

front 15

ACTIVITY 6: RENAL RESPONSE TO RESPIRATORY ACIDOSIS

EXPLAIN HOW THE RENAL SYSTEM COMPENSATED FOR RESPIRATORY ACIDOSIS.

back 15

PENAL SYSTEM COMPENSATES FOR RESPIRATORY ACIDOSIS BY DECREASING PCO2 LEVELS AND INCREASING pH LEVELS.

front 16

ACTIVITY 6: RENAL RESPONSE TO RESPIRATORY ACIDOSIS

WHICH TYPE OF BREATHING RESULTS IN RESPIRATORY ACIDOSIS?

back 16

REBREATHING

front 17

ACTIVITY 8: RESPIRATORY RESPONSE TO INCREASED METABOLISM

WHAT WASTE PRODUCT IS INCREASED WITH AN INCREASED RATE OF METABOLISM?

back 17

METABOLIC WASTE PRODUCT

front 18

ACTIVITY 8: RESPIRATORY RESPONSE TO INCREASED METABOLISM

WHICH METABOLIC RATES RESULTS IN METABOLIC ACIDOSIS?

back 18

METABOLIC RATES OF 70 AND 80

front 19

ACTIVITY 8: RESPIRATORY RESPONSE TO INCREASED METABOLISM

LIST SOME OTHER POTENTIAL CAUSES OF METABOLIC ACIDOSIS.

back 19

KETO ACIDOSIS, SALIVYLATE POISONING, INGESTING TOO MUCH ALCOHOL, DIARRHEA, AND STRENUOUS EXERCISE.

front 20

ACTIVITY 9: RESPIRATORY RESPONSE TO DECREASED METABOLISM

WHICH METABOLISM RATES RESULTED IN METABOLIC ALKALOSIS?

back 20

METABOLIC RATES OF 30 AND 20

front 21

ACTIVITY 9: RESPIRATORY RESPONSE TO DECREASED METABOLISM

LIST SOME OTHER POTENTIAL CAUSES OF METABOLIC ALKALOSIS.

back 21
