Hand in hand for better patient care

FLOW-i and ProAQT

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

Anesthesia-induced lung collapse is a well-known entity which can be avoided by a good ventilatory strategy. FLOW-i’s new lung recruitment maneuver aims to gently open the alveoli to make a lasting diff erence for your patients (3).

A good ventilatory strategy involves a good hemodynamic strategy

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

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

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

ProAQT Sensor and PulsioFlex Monitor

• Minimally invasive

• Easy to attach to aterial line

• Continuous trend monitoring

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.

FLOW-i Recruitment Maneuver (RM)

• Stepwise

• Automatic

• Dynamic compliance continously displayed

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.
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)

Fluid management fact

37 % – 55 %

of postoperative complications can be prevented through perioperative goal directed fluid therapy (2,6)

Prediction of Fluid Responsiveness

The degree of stroke volume reduction induced by an lung recruitment maneuver can represent a functional test to suggest preload responsiveness and, therefore, predict fluid responsiveness (5).
