01a. Acute Responses - Respiratory

Question 1

List 5 acute respiratory responses

Answer 1

Increased TV, RR, V, pulmonary diffusion and 02 uptake.

Question 2

Define Tidal Volume

Answer 2

The amount of air inhaled and exhaled per breath

Question 3

Define Respiratory Rate

Answer 3

Number of breaths per minute

Question 4

Define Ventilation

Answer 4

The total amount of air breathed in and out per minute (TV x RR = V)

Question 5

Define Gaseous Exchange

Answer 5

The movement of gases from areas of high concentration to areas of low concentration.

Question 6

Pulmonary Diffusion

Answer 6

Diffusion of 02 from the alveoli into the blood and CO2 out of blood into alveoli

Pulmonary means lung

Question 7

What happens to tidal volume TV as intensity increases from sub max to max and why?

Answer 7

What - It plateaus
Why - it reaches its maximum already due to its finite capacity.

Question 8

What is the amount of air inhaled and exhaled per breath?

Answer 8

Tidal Volume (TV)

NOTE - always write out in full

Question 9

What is the number of breaths per minute?

Answer 9

Respiratory rate (RR)

NOTE - always write out in full

Question 10

What is the total amount of air breathed in and out per minute ?

Answer 10

Ventilation (TV x RR = V)

Question 11

What is the movement of gases from areas of high concentration to areas of low concentration called?

Answer 11

Gaseous exchange

Question 12

What is diffusion of 02 from the alveoli into the blood and CO2 out of blood into alveoli called?

Answer 12

Pulmonary diffusion
