Lung Function and Spirometry

What is pulse oximetry used to measure?

• Oxygen level in the blood

• Respiratory rate

• Heart rate

• Lung volume

What does spirometry measure?

• Blood oxygen saturation

• Lung volumes and airflow

• Pulse rate

• Heart rate

What is the total lung capacity (TLC) formula?

• TLC = TV + IRV + ERV

• TLC = VC + RV

• TLC = VC + TV

• TLC = IRV + RV

Which lung volume refers to the air inhaled and exhaled without conscious effort?

• Tidal Volume (TV)

• Inspiratory Reserve Volume (IRV)

• Residual Volume (RV)

• Vital Capacity (VC)

What type of disease is characterized by inflammation and excessive mucus production in the airways?

Which of the following is a type of lung disease?

• Obstructive airway diseases

• Restrictive lung diseases

• Cardiac diseases

• Neurogenic disorders

What is the main purpose of a peak flow meter?

• Measure oxygen level in the blood

• Monitor how open the airways are

• Measure lung volume during exhalation

• Measure pulse rate

What is a common result of obstructive airway diseases such as asthma?

• Increased lung capacity

• Difficulty exhaling air

• Increased tidal volume

• Reduced vital capacity

Which of the following lung volumes cannot be measured by spirometry?

• Tidal Volume (TV)

• Inspiratory Reserve Volume (IRV)

• Residual Volume (RV)

• Expiratory Reserve Volume (ERV)

What does FEV1 stand for?

• Forced Exhaled Volume in 1 second

• Forced Expiratory Volume in 1 second
