What characteristic does the flow graph in Pressure Control Ventilation exhibit during inspiration?
Understand the Problem
The question is asking about the characteristics of the flow graph specifically during inspiration in the context of Pressure Control Ventilation, which is related to medical ventilation techniques.
Answer
Decelerating flow pattern during inspiration.
The flow graph in Pressure Control Ventilation exhibits a decelerating flow pattern during inspiration.
Answer for screen readers
The flow graph in Pressure Control Ventilation exhibits a decelerating flow pattern during inspiration.
More Information
In Pressure Control Ventilation (PCV), the flow decreases over time during the inspiratory phase because the preset pressure limits the flow rate as the lung fills. Unlike volume-controlled ventilation, where flow remains constant, PCV results in a decelerating flow pattern.
Tips
A common mistake is confusing Pressure Control Ventilation with Volume Control Ventilation where a constant flow pattern is observed. Understanding the difference helps in proper graph interpretation.
