Covidien will feature the expanded capabilities of its PURITAN BENNETT 840 ventilator with a Respiratory Mechanics (RM) software option at SCCM 2008.
The RM option allows clinicians to assess lung status and performance to help determine if a patient is ready to be weaned by providing an occlusion pressure maneuver (P0.1), plus coached respiratory maneuvers such as negative inspiratory force (NIF) and vital capacity (VC). A reportedly easy-to-read GUI information panel clearly displays the maneuver name, user prompts and controls and recent measured results. In addition, the last three values for NIF, P0.1 and VC are saved and displayed in tabular form for historical data collection.
