Up close and personal. The stories of INTELLiVENT-ASV

We are sure you have heard the story of automation in mechanical ventilation. But there are so many more stories than just that one! Join our experts as they tell you their stories about the many faces of INTELLiVENT-ASV: As the protector of both the lungs and the brain, as the chameleon who adapts to every patient condition, as your assistant at every bedside, even up in the air. We look to forward to seeing you on air with our experts.

Webinar 1. INTELLiVENT-ASV: Everything you need to close the loop

Below you can find the answers to those questions not addressed during the webinar and follow the link to access the webinar's recording.

This depends on the patient's disease and lung condition, but for example in ARDS patients it is common to target a somewhat lower SpO2 of 90-94% to prevent excessive oxygen use and thus help prevent VILI. This usually results in a lower level of oxygen.

We used and still use APV-CMV (adaptive pressure ventilation), pressure controlled ventilation, pressure support ventilation and ASV.

When there is a measurement failure for any reason, INTELLiVENT-ASV will stop adjusting and freeze settings, and will generate alarms. If there is no solution at that time, i.e., SpO2 measurement due to poor perfusion, you can choose to set the controller to 'manual'.

The set I:E ratio by INTELLiVENT‑ASV is based on the RCexp, also known as the time constant. Meaning that there is a measurement of the duration of expiration based on lung mechanics and the expiration time will adjust to that. For example, for a lung with high compliance like COPD, INTELLiVENT‑ASV will set a longer expiration time and therefore prevent for auto‑PEEP.

Indeed, you try to ensure the best measurement with different options, and if the quality of the measurement is poor due to the illness of the patient, you can choose to set the controller to 'manual' until measurements are improved, then you can turn back to 'automatic'.

This is a matter of setting PEEP limits well or if necessary you can always set PEEP to 'manual'. Then you still have the advantage of automated adjustments of FiO2 and automated setting and adjustments of the VT/RR combination.

We have used it in these patients, but comparable to conventional ventilation you still need to check tidal volumes, pressures and adjust where necessary.

I think this is comparable to conventional ventilation, where you also check the pCO2 in the arterial blood gas and adjust settings where necessary.

In my experience, there are no unwanted pressure drops in spontaneously breathing patients.

Regarding implementation, this could be a webinar of its own :). Our team is focused on innovation and there are good arguments for using INTELLiVENT-ASV.

Well, as explained in the webinar, as a user you are still in control and are supervising the ventilator and adjusting targets, limits and settings, if necessary with measurements like Vd/Vt and pH.

There is, in my opinion, not a specific difference between these patient groups, good results achieved in both groups.

No, this is the responsibility of the caregiver, because you are still in control of settings, limits and additional measurements for setting ventilation parameters. 

The logic behind selecting a specific breathing pattern (Vt and RR) is based on lung mechanics, and it’s clearly described in literature. The algorithms used by INTELLiVENT-ASV for CO2 elimination and oxygenation are based on patient signals and user-set targets and limits. The way INTELLiVENT-ASV sets the parameters based on lung mechanics and "how and why" is available in the ventilator's operator’s manual, as well as in the clinical literature.
