BME314 Respiratory Measurements

It is the act or process of breathing. The exchange of gases in any biological process.

Which of the following below is a correct pathway of air?

• Nose-Pharynx-Larynx-Trachea-Alveoli-Bronchi

• Nose-Larynx-Pharynx-Trachea-Bronchi-Alveoli

• Nose-Pharynx-Larynx-Trachea-Bronchi-Alveoli

• Nose-Pharynx-Larynx-Bronchi-Trachea-Alveoli

Which of the following statements are false?

• Pulmonary function tests are a group of tests that measure breathing, gas exchange, and how well the lungs are functioning.

• Carbon dioxide moves from the alveoli to the blood in the capillaries, and oxygen moves from the blood in the capillaries to the air in the alveoli.

• External respiration is the exchange of gases between the

  bloodstream and nearby cells.

• The diaphragm and external intercostal muscles are primary muscles of inspiration.

It is the extra volume of gas that a person can inspire with maximal effort after reaching the normal end inspiratory level.

• Tidal Volume

• Inspiratory reserve volume

• Residual Volume

• Total lung capacity

• Forced expiratory volume (FEV)

A measure of the lung expandability is called_________ and resistance of the air passages is generally called _________.

• Respiratory rate; Airway Resistance

• Lung compliance; Respiratory rate

• Lung compliance; Airway Resistance

• Lung sounds; Airway Resistance

It is a diagnostic device that measures the amount of air you're able to breathe in and out and the time it takes you to exhale completely after you take a deep breath.

Which of the following can be measured by a spirometer?

• Forced Expiratory Volume (FEV)

• Residual Volume (RV)

• Tidal Volume (TV)

• Total Lung Capacity (TLC)

What is shown in the given image?

• Body Plethysmograph

• Recording Spirometer

• Incentive Spirometer

• Pneumotachometer

• Blood Gas Analyzer

A medical device that can be used to measure Functional Residual Capacity of the lungs.

• Spirometer

• Body Plethysmograph

• Ventilator

• Kymograph

• Humidifier

Which of the following statements are true?

• Pneumotachograph is a device that measures airflow quantitatively by detecting flow of respiratory gases and comparing it to the pressure drop against a small resistive field.

• The usual output of a spirometer is the flowgram.

• The mechanics of breathing does not follow Boyle's Law.

• The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.
