While recognising that every patient is different, VPAP devices are designed for quick and easy out-of-box performance.

 

For most patients, the default (Medium) trigger and cycle settings offer effective synchronisation with the patient’s effort to breathe.

 

The need to customise therapy

However, trigger and cycle synchrony may be a challenge for some patients with altered lung mechanics. Triggering and cycling depend on monitoring respiratory flow to determine the patient’s effort. A lack of synchrony is caused by differences in lung mechanics and can

be overcome by adjusting the Trigger and Cycle Sensitivities.

 

Flexibility to customise therapy

VPAP devices offer five levels of Trigger and Cycle sensitivity to fine-tune synchronisation, accommodating a wide variety of patient types.

 

How it works

The default Medium settings work well for most patients. Higher and lower sensitivity settings offer flexibility based on the patient's condition. Five levels of Trigger and Cycle Sensitivities help to fine-tune synchrony, accommodating even the most challenging patient.

 

Trigger and Cycle Sensitivities rely on Vsync to accurately measure patient respiratory flow. Working together, these technologies provide optimal synchronisation.

 

Why use it?

Adjustable Trigger and Cycle Sensitivities can be used to match the device response to the patient's lung mechanics, and improve breath synchrony and overall efficacy of treatment.

 

More sensitive trigger and cycle settings (i.e. High and Very High) are for patients with high resistance, including paediatric patients and those with obstructive lung mechanics. For these patients, weak efforts and/or intrinsic PEEP make it difficult to trigger.

 

Less sensitive settings (i.e. Low and Very Low) are available for patients prone to auto-triggering. This can occur with restrictive mechanics and longer expiratory pauses, with cardiogenic oscillation and other noise at end-expiration triggering the device.

 

The simple adjustment of Trigger and Cycle Sensitivity goes a long way to maintain patient–device synchrony.
