Final answer:
The incorrect statement about controlled ventilation is that therapists have little control over inspiratory flow and pressure. Contrarily, they have the ability to adjust both the tidal volume and respiratory rate to suit the patient's requirements. The correct option is d.therapist has little control of needed inspiratory flow and pressure
Step-by-step explanation:
The student asked which of the following statements is NOT true regarding the use of controlled ventilation:
- May allow the muscles breathing to rest.
- It can use a larger I: E ratio and may improve oxygenation.
- Requires use of paralytic agents in spontaneously breathing patients.
- The therapist has little control of needed inspiratory flow and pressure.
The statement that is NOT true is that the therapist has little control over needed inspiratory flow and pressure. In reality, with controlled ventilation, therapists can regulate both the volume of air per breath (tidal volume) and the rate at which it is delivered (respiratory rate). Therefore, the therapist does have control over the inspiratory flow and pressure to meet the patient's needs.
The correct option is d.therapist has little control of needed inspiratory flow and pressure
