What is collateral ventilation?

Ventilation of alveoli via pathways that bypass the normal airways (correct)

Ventilation of the upper respiratory tract

Ventilation of the trachea only

Ventilation of alveolar structures through the normal airways

Which treatment approaches are supported by collateral ventilation?

Antibiotic therapy and coughing exercises

Inspiratory holds and breathing control (correct)

Surgical interventions only

Cardiovascular exercises

What is the purpose of collateral ventilation when airways are obstructed?

To preserve ventilation and gas exchange in distal parts of the lung (correct)

To reduce gas exchange in distal parts of the lung

To increase the risk of respiratory failure

To stop all ventilation in the lungs
