PhysioEx 9.1 Exercise 7 Respiratory System Mechanics

Which of the following respiratory values represents a decreased flow rate during the obstructive lung disease(s)?

FEV1

To calculate a person's vital capacity, you need to know the TV, ERV, and ______

IRV

What is the largest volume for the normal patient?

IRV

The addition of surfactant to the lung interior

Increased airflow

What happened to the RV for the emphysema patient and the asthmatic patient?

It increased for both patients

The best way to rapidly re-inflate a person's collapsed lung is to?

Pump air out of the intrapleural space to recreate negative pressure

For a person suffering an asthma attack, inhaler medications are expected to _______?

Reduce the airway resistance

Calculate the FVC of an individual with the following respiratory volumes: RV = 1000 ml, IRV = 3000 ml, TV = 500 ml, ERV = 1500 ml

5000 ml

Calculate the ERV of an individual with the following respiratory volumes: TLC= 6000 ml, FVC=4800 ml, RV= 1200 ml, IRV= 2900 ml, TV= 500 ml

1400 ml

In this activity a pneumothorax is automatically followed by

Atelectasis

Opening the valve in the side of the glass bell jar

Simulated pneumothorax

Which of the following values does not include the ERV?

TV

Measuring a person's FVC means that you are measuring what?

The amount of air that can be expelled when the subject takes the deepest possible inspiration and then forcefully expires as completely and rapidly as possible.

Measuring a Person's FEV1 means that you are measuring what?

The amount of the VC that is expired during the first second of the FVC test.
