Respiration

Question 0

Inspiratory reserve volume (IRV)

Answer 0

Maximum volume above tidal volume that we can inhale

Question 1

vital capacity (VT)?

Answer 1

Volume breathed in and out in each breath

Question 2

expiratory reserve volume (ERV)

Answer 2

Maximum volume we can exhale from lungs at the end of a normal breath

Question 3

Residual volume (RV)

Answer 3

The volume of air remaining in the lungs which is impossible to expire

Question 4

Expiratory capacity (EC)

Answer 4

Volume of air that we can expire after normal inspiration

= VT + ERV

Question 5

Inspiratory capacity (IC)

Answer 5

All the air we breath in during maximum inhalation

= VT + IRV

Question 6

Functional Residual Capacity (FRC)

Answer 6

Volume of air remaining in the lungs at the end of normal expiration
= ERV + RV

Question 7

Total lung capacity (TLC)

Answer 7

All the air the lungs can contain

= IRV + ERV + VT + RV

Question 8

Vital capacity (VC)

Answer 8

All the air that can be expired following maximum inhalation
= ERV + VT + IRV

Question 9

Forced vital capacity (FVC)

Answer 9

Volume of lungs from full inspiration to forced expiration

Question 10

FEV1

Answer 10

Volume of air expelled in the first second of a forced expiration

Question 11

What is dyspnea?

Answer 11

Refers to difficulty in breathing

Question 12

Answer 12

• Pneumothorax
• Acute asthmatic attacks
• Pneumonia
• Myocardial infarction
• Rapid developing heart failure

Question 13

Major respiratory diseases associated with chronic dyspnea

Answer 13

• Chronic obstructive pulmonary disease (COPD)

* Restrictive lung disease

Question 14

In spirometry what is the apparatus used?

Answer 14

A pneumotachometer
