To obtain absolute lung volume
What is a primary goal of mechanical ventilation?
Increase respiratory rate.
Decrease work of breathing
Enhance lung capacity.

Why is the observation of symmetry in oral movement crucial?
It indicates speech clarity.
It reflects muscle tone and control.
It shows dental health.
It reveals cognitive abilities.
It reflects muscle tone and control
What is the difference between ventilation and respiration?
Ventilation involves gas exchange, respiration does not.
Ventilation is the movement of gas; respiration is gas exchange.
They are the same process.
Ventilation is voluntary, respiration is involuntary.
Ventilation is the movement of gas, respiration is gas exchange
