Monitoring Lung Function with Electrical Impedance Tomography in the Intensive Care Unit
Published on: September 6, 2024
Abstract:
Intensive care ventilators provide temporary ventilatory support to critically ill patients who cannot breathe on their own or who require assistance to maintain adequate ventilation. These ventilators offer a wide range of capabilities and can meet the needs of many types of patients. We last evaluated intensive care ventilators for adult use in our July-August 2000 issue. In the current Evaluation, we revisit the ratings of nine previously evaluated ventilators and describe our findings for one newly evaluated unit, the Siemens Servo-i. As ventilator technology has evolved, so have our ratings. Several units have added new features and capabilities since we last examined them. As a result, we have rated them higher in this study. Conversely, a few models have been given lower ratings because they haven't kept up with the advances in the technology; although they perform adequately, we can no longer recommend their purchase because better choices are available.
