PhEx 8 Respiratory please help

The rate of respirations increased when breathing resumed.


80%

Thank you 

I figured out the other answers Thank you for your help!

Could you help me out and post them

Yes, do you need all the answers or just the 18-24? I hope this helps I just write the shortest answer possible but you can put it in your own words if you understand the answers Let me know if this helps and if you need more help!

18. What was the value of the PCO2 with breath holding? Explain any difference.

The levels increased, when more CO2 is taking in total air flow is increased.

19. Was there a change in the rate of respirations when the breathing was resumed?

The rate increased

The following questions refer to Activity 6: Comparative Spirometry.
20. What was the value obtained for the (FEV1/FVC) x 100% with “normal breathing”?

 80%

21. What effect did “emphysema breathing” have on FVC and FEV1?

It reduced

22. In “emphysema breathing” which of the two values, FVC and FEV1 changed the most?

FEV1

23. What effect did “acute asthma attack breathing” have on FVC and FEV1?

It was reduced

24. In “acute asthma attack breathing” which of the two values, FVC and FEV1 changed the most?

FEV1

physgirl..... do you have the answers for activity 2,3,4 ii actually needed these to.

Here you go hope it helps
The following questions refer to Activity 2: Examining the Effect of Changing Airway Resistance on Respiratory Volumes.
4. How did changing the radius effect FEV1 (%)?

When decreasing radius you caused a decrease in the FEV1 %

5. What was the FEV1 at a radius of 5.00 mm?

73.9%

6. Do the results suggest that there is an obstructive or restrictive problem? Explain.

There is no problem, the airway is at normal radius.
Simulating Factors Affecting Respirations

The following questions refer to Activity 3: Examining the Effect of Surfactant.
7. What effect does the addition of surfactant have on the airflow?

It causes increased airflow

8. Why does surfactant affect airflow?

It causes reduced surface tension in the alveoli, so the alveoli can expand more.

9. Why do premature infants have difficulty breathing?

They don’t have enough surfactant

The following questions refer to Activity 4: Investigating Intrapleural Pressure.
10. What effect does opening the valve have on the left lung? Why does this happen?

It collapses cause intrapleural and atmospheric pressure are the same.

11. What condition does opening the valve simulate?

Pneumothorax

12. What is the value of the pressure in the left lung when the valve is opened?

0.00

13. What happened to the total flow when the valve was opened?

It was half the flow . Less than when both lungs were working.

14. In the last part of this activity, when the reset button was clicked, what procedure would be used with real lungs?

You would insert a chest tube to remove the air
