Which mode allows a patient to have spontaneous breaths along with mechanical support?

• A. CSV
• B. SIMV
• C. AC
• D. IMV

Answer: (B)

The mode that allows a patient to have spontaneous breaths along with mechanical support is SIMV, which stands for Synchronized Intermittent Mandatory Ventilation. This mode is designed to provide a balance between mandatory mechanical breaths and the patient's own spontaneous breathing efforts. In SIMV, the ventilator delivers a set number of breaths at a predetermined tidal volume, which is synchronized with the patient's own breathing efforts. If the patient initiates a breath, the ventilator allows for spontaneous breathing and supports that breath without forcing mechanical ventilation. This is particularly beneficial for patients who are starting to regain their ability to breathe independently, as it encourages the patient to participate in their own ventilation while still providing adequate respiratory support when necessary. This type of ventilation is often used in weaning patients off mechanical ventilation, as it offers a compromise between full ventilatory support and complete freedom of spontaneous ventilation. The other modes listed, such as CSV (Continuous Positive Airway Pressure), AC (Assist-Control), and IMV (Intermittent Mandatory Ventilation), either do not allow for spontaneous breaths or do not provide the same level of synchronization and support as SIMV.
