What is the recommended adjustment to correct trigger asynchrony in mechanical ventilation?

Trigger asynchrony occurs when there is a mismatch between the patient's attempts to initiate a breath and the ventilator's response to those attempts. This can lead to patient discomfort and ineffective ventilation. The recommended adjustment to correct trigger asynchrony involves recognizing and adjusting the trigger sensitivity.

By adjusting the trigger sensitivity, the ventilator can become more responsive to the patient's efforts to initiate a breath. If the trigger sensitivity is set too high, the ventilator may fail to respond to the patient's attempts, leading to asynchrony. Conversely, if it's set too low, it may respond to non-intentional efforts, again causing issues. Therefore, fine-tuning the trigger sensitivity ensures that the ventilator supports the patient's breathing efforts effectively, improving synchronization between the patient and the ventilator.

While increasing inspiratory time and setting a higher flow rate can help address other ventilation issues, they do not directly solve the problem of trigger asynchrony. Changing the patient-ventilator mode might provide a different breathing pattern but does not specifically address the underlying issue of trigger sensitivity. Recognizing and adjusting trigger sensitivity is the most direct and effective action for resolving this specific problem.
