Airway New 2025

The exchange of gases with the external environment, and occurs in the alveoli of the lungs.

• Urination

• External respiration

• Internal respiration

• Cellular respiration

Endotracheal Intubation Indications include which of the following

• Cardiac/Respiratory arrest

• Airway burns

• Airway swelling

• Respiratory failure

Answer explanation

An I gel could also be used for the respiratory failure, and cardiac/respiratory arrest patient, however ONLY an ET tube should be used for airway swelling and burns as it is able to isolate the airway!

A physiological mechanism that helps regulate breathing and prevent over-inflation of the lungs

• Cheyne-Stokes respiration
• Hering-Breuer reflex
• Kussmaul breathing
• Gag reflex

Answer explanation

The gag reflex is to prevent foreign material from entering the trachea and lungs.

Cheyne-stokes and Kussmauls are breathing paterns.

The portion of each breath that does not participate in gas exchange

• Internal respiration

• External respiration

• Anatomical dead space

• Physiological dead space

State in which insufficient oxygen is available to meet the oxygen requirements of the body's cells, tissues, or organs.

• Hypoxia

• Hypercapnia
• Cyanosis

Answer explanation

Hypocarbia is a condition in which the level of carbon dioxide (CO2) in the blood is lower than normal

The exchange of gases with the internal environment, and occurs in the tissues

• Residual volume
• Inspiratory reserve volume
• Anatomical dead space

Answer explanation

Approximately 150 mL in an adult male patient

• When lungs are less ______ (more stiff), it takes more pressure to inflate them, which can make BVM ventilation harder and potentially lead to complications. 

• elastic

• compliant
• expandable
