What is the typical first sign of possible ventilator malfunction during patient breathing cycles?

• A. Decrease in tidal volume.
• B. Increase in respiratory rate.
• C. Decrease in oxygen saturation.
• D. Increase in peak pressure.

Answer: (D)

The typical first sign of possible ventilator malfunction during patient breathing cycles is an increase in peak pressure. This is significant because the ventilator's peak pressure reading reflects the maximum pressure required to deliver a breath to the patient. When there is a malfunction, such as increased resistance in the airway (due to issues like secretions, blockages, or kinks in the tubing), the ventilator must exert more force to deliver the set tidal volume. This translates into a higher peak pressure reading, indicating that the system is encountering difficulties. Monitoring peak pressure is crucial in identifying potential problems early. If peak pressures rise unexpectedly, it alerts clinicians that further investigation is needed to assess the patient's airway and the functioning of the ventilator. This proactive approach can lead to the identification and resolution of issues before they critically affect patient safety or respiratory function.
