Some patients who are restless when waking may appear to be caused further discomfort by INTELLiVENT-ASV making multiple adjustments, such as increasing %MinVol, PEEP or oxygen. Some users may immediately want to switch to spontaneous mode to avoid this.

INTELLiVENT-ASV seemingly causing discomfort for waking patient

Causes and corrective action

Such discomfort in patients transitioning from passive to spont may be caused by the following:

A decrease in the patient’s SpO2 and an increase in PEEP. In this case, it may help to set a PEEP limit in the INTELLiVENT-ASV settings in spontaneous breathing patients.
Patient ventilator asynchrony. Ensure that inspiratory trigger, rise time and expiratory trigger sensitivity are set according to the patient.
An increase in respiratory rate resulting in an increase in %MinVol. Check and solve the reason for the increased respiratory rate:
- If the patient needs ventilatory support, INTELLiVENT-ASV will react accordingly by increasing %MinVol.
- Treat anxiety, “subjective” dyspnea, or agitation according to your hospital protocol.
