  • Title: Ventilator Graphics: Scalars, Loops, & Secondary Measures.
    Author: Dexter AM, Clark K.
    Journal: Respir Care; 2020 Jun; 65(6):739-759. PubMed ID: 32457168.
    Abstract:
    Ventilator graphic monitoring is common in ICUs. The graphic information provides clinicians with immediate clues regarding patient-ventilator interaction and ventilator function. These display tools are aimed at reducing complications associated with mechanical ventilation, such as patient-ventilator asynchrony. It is also useful to assess respiratory mechanics in mechanically ventilated patients using both scalar and plot displays on the ventilator. Additional information can be gained by observing secondary ventilator measures including stress index, inflection points, and work of breathing. Ventilator graphics impact mechanical ventilation management through optimizing effectiveness of patient care and enhancing promptness of clinician response. Despite being a valuable asset in providing high-quality patient care, many bedside clinicians do not have a thorough understanding of ventilator graphics. Mastery of ventilator graphics interpretation is key in managing patients who are receiving ventilatory support.
