"A good ventilatory strategy involves a good haemodynamic strategy“

Carlos Ferrando MD, PhD, EDAIC
Dept of Anesthesiology, Clinic Hospital, University of Valencia, Spain

Did you know that atelectasis affects over 90 % patients undergoing surgery?[3]

Anaesthesia-induced lung collapse is a well-known entity which can be avoided by a good ventilatory strategy. FLOW-i’s new lung recruitment manoeuver aims to gently open the alveoli to make a lasting difference for your patients.

Postoperative pulmonary complications



Local inflammatory response

Ventilator induced lung injury

In the automatic recruitment manoeuver, a stepwise increase in pressure is applied for a time period set by the user. It’s designed to reduce the occurrence of haemodynamic compromise. In combination with the ProAQT technology it is possible to detect any haemodynamic changes automatically, continuously and in real time – prior, during and after an recruitment manoeuver.

Lung protective ventilation helps

In a stepwise recruitment manoeuver there will be less haemodynamic compromise.

Lung recruitment with Maquet FLOW-i allows you to choose between an automatic or manual manoeuver. Whichever you choose, the recruitment will be stepwise. FLOW-i measures and displays the dynamic compliance in real time, which is used to find the optimal lowest PEEP that keeps the lungs open.

Advanced haemodynamic monitoring helps

Use of Advanced Patient Monitoring shows the response of your patient to lung recruitment.

The change of CO and SV is detected in realtime. Also Preload (SVV, PPV), Afterload (SVRI) and Contractility (dPmx, CPI) parameters provide clinicians better insights.

Occult hypovolemia can be detected prior to the recruitment manoeuver followed by appropriate perioperative fluid management that will decrease post-surgical complications.

Heart-lung interactions during the recruitment manoeuver can be monitored by the ProAQT technology

Visualise haemodynamic conditions


Fluid management fact

37 % – 55 %

of postoperative complications can be prevented through perioperative goal directed fluid therapy.[2] [6]

Safety and simplicity for lung recruitment in the OR


Lung recruitment fact

5 % – 10 %

of all surgical patients develop Postoperative Pulmonary Complications (PPCs).
In thoracic or abdominal surgeries even up to 30 – 40 % develop PPCs.[1]
