Question 28

Answer 28

The instrument we used to measure the respiratory volumes; a lightweight metal bell inverted in a drum filled with water

Question 29

The instrument we used to measure the respiratory volumes; a lightweight metal bell inverted in a drum filled with water

Answer 29

Spirometer

Question 30

Calculating Tidal Volume

Answer 30

Multiply your Tidal Volume by your Respiratory Rate per minute to give your Respiratory Minute Volume Respiratory Minute Volume = TV X Breathing Rate (mL air / min) = TV X (breaths/min) TV = mL air / breath

Question 31

How did we find tidal volume?

Answer 31

Set spirometer to zero. Take a normal inspiration, place your mouth over the mouthpiece, and exhale a normal expiration into the spirometer

Question 32

How did we find expiratory reserve volume?

Answer 32

Set the spirometer to zero. After a normal expiration, place your mouth over the mouthpiece and forcefully exhale as much air as possible into the spirometer

Question 33

How did we find vital capacity?

Answer 33

Set spirometer to zero. Inhale as deeply as possible; place your mouth over the mouthpiece, hold your nose, and exhale into the spirometer with a maximal effort. Then use the table for predicted vital capacity based on your age, height, and sex

Question 34

How do we calculate the inspiratory reserve volume (IRV)?

Answer 34

Vital Capacity - Tidal Volume - Expiratory Reserve volume

Question 35

How do we calculate the Inspiratory Capacity (IC)?

Answer 35

Vital Capacity - Expiratory Reserve Volume

Question 36

In this test the subject takes five deep breaths and then holds his breath as long as possible after the last inspiration. Gives an indication of the person's functional respiratory reserve and efficiency of his respiratory system. Often a better index of respiratory reserve than is the traditional vital capacity measurement.

Answer 36

Heymer Test

Question 37

Heymer Test

Answer 37

In this test the subject takes five deep breaths and then holds his breath as long as possible after the last inspiration. Gives an indication of the person's functional respiratory reserve and efficiency of his respiratory system. Often a better index of respiratory reserve than is the traditional vital capacity measurement.

Question 38

50-70 seconds

Question 39

Answer 39

50-60 seconds

Question 40

Measures the volume of gas that passes through it

Answer 40

Dry gas meter

Question 41

Answer 41

Douglas bag

Question 42

Units for Minute Volume (Vm)

Answer 42

ml air / min

Question 43

Units for breathing rate (BR)

Answer 43

Breaths / minute

Question 44

Units for heart rate (HR)

Answer 44

beats / minute

Question 45

In the respiratory system, the flow of air is called the

Answer 45

Minute Volume (Vm)

Question 46

In the circulatory system, the flow of blood is called the

Answer 46

Cardiac Output (CO)

Question 47

How do we calculate metabolic rate or oxygen consumption (VO2)?

Answer 47

VO2 = (Vm)(CO2i - CO2e) = (CO)(CO2a - CO2v) | ml O2 / min

Question 48

In most resting people, arteriole blood is 100% saturated w/ oxygen, but mixed venous blood is only

Answer 48

60% saturated

Question 49

How did we calculate the oxygen content of arteriole blood (CO2a)?

Answer 49

Assuming you have the average hemoglobin concentration and each gram of hemoglobin can bind with 1.3 ml of O2 CO2a = (13.3 g hemoglobin / 100 ml blood) X (1.3 ml O2 / 1 g hemoglobin)

Question 50

How did we calculate the oxygen content of venous blood (CO2v)?

Answer 50

CO2v = 0.6 (CO2a)

Question 51

In our hw how did we calculate cardiac output (CO)?

Answer 51

CO = VO2 / (CO2a-CO2v) | [ml blood/min]

Question 52

In our hw how did we calculate stroke volume?

Answer 52

SV = CO / HR | [ml blood / beat]

Question 53

In our hw how did we calculate total peripheral resistance (TPR)?

Answer 53

TPR = mean arterial pressure / CO closely equal to; [(systolic + 2 diastolic)/3] / CO
