What is a primary feature of IMV?

• A. Controlled breaths are synchronized with patient efforts
• B. Controlled breaths are delivered only when the patient is not breathing
• C. Spontaneous breaths are completely suppressed
• D. Patient receives only mandatory breaths

Answer: (B)

The primary feature of Intermittent Mandatory Ventilation (IMV) is that it allows for controlled breaths to be given at set intervals while also enabling the patient to take spontaneous breaths in between. This means that breaths can be synchronized with patient efforts, allowing for a combination of mandatory and spontaneous ventilation. In this context, saying that controlled breaths are delivered only when the patient is not breathing does not accurately reflect the characteristic of IMV, as it typically allows for patients to breathe on their own between the mandatory breaths. In fact, the design of IMV aims to support respiration while promoting independence by giving patients the opportunity to initiate breaths at their own pace. Because of this fundamental characteristic, IMV is particularly beneficial in weaning patients off mechanical ventilation, helping them to regain their breathing capability while still providing necessary support. Thus, it emphasizes both support and patient autonomy within the ventilation process.
