How ASV works

11.09.2017
Author: Hamilton Medical, Reviewer: NA

The intelligent ventilation mode Adaptive Support Ventilation (ASV®) adjusts respiratory rate, tidal volume, and inspiratory time breath-by-breath, 24 hours a day, depending on the patient’s lung mechanics and effort.

Setting PEEP using transpulmonary pressure measurement

11.09.2017
Author: Hamilton Medical, Reviewer: NA

One of the greatest challenges when mechanically ventilating patients is finding the correct setting for positive end-expiratory pressure (PEEP). This task can be made easier by using transpulmonary pressure measurement to distinguish between the pressure in the lungs and the chest wall components.

Volumetric capnography

11.09.2017
Author: Hamilton Medical, Reviewer: NA

By knowing how CO2 behaves on its way from the bloodstream through the alveoli to the ambient air, you can obtain useful information about ventilation and perfusion. Monitoring the CO2 level during respiration (capnography) is noninvasive, easy to do, and relatively inexpensive.

Bedside tip: How to select SpO2 targets

Bedside tip: How to measure driving pressure

09.05.2017
Author: Clinical Experts Group, Hamilton Medical, Reviewer: Paul Garbarini, David Grooms

Airway driving pressure is associated with clinical outcomes in ARDS, post-surgical, and normal-lung patients, and is a measure of the strain applied to the respiratory system and the risk of ventilator-induced lung injuries. Evidence suggests we should keep driving pressure below 14 cmH2O. But how can we measure it?

driving pressure, hold maneuver, end-expiratory, end-inspiratory, plateau pressure, PEEP, ASV

Bedside tip: How to wean with ASV®

03.04.2017
Author: Dr. med. Jean-Michel Arnal, Senior Intensivist, Hopital Sainte Musse, Toulon, France, Reviewer: Paul Garbarini

The American Thoracic Society and the American College of Chest Physicians recently provided recommendations to help optimize liberation from mechanical ventilation in adult ICU patients (1). They suggest using a ventilator liberation protocol and performing spontaneous breathing trials (SBTs) with modest inspiratory pressure support (5-8 cmH2O). So how do we implement these recommendations using the Adaptive Support Ventilation (ASV) mode?
