TAILIEUCHUNG - Emergency medicine and mechanical ventilation: Part 2

(BQ) Continued part 1, part 2 of the document Emergency medicine and mechanical ventilation has contents: Understanding the ventilator screen, placing the patient on the ventilator, case studies in mechanical ventilation, troubleshooting the ventilated patient. Invite you to refer. | Chapter 6 Check far updates Understanding the Ventilator Screen Ventilators at times seem intimidating as there are numerous waveforms and values on the screen. Additionally the data are presented slightly differently on the screens of each mechanical ventilator brand increasing confusion. However using the terms we have just reviewed close inspection of ventilator screens will show that most of the waves and data are actually simple given a little familiarity. To increase clinicians comfort with ventilator screens we have deliberately selected screenshots from a few different types of machines and modes of ventilation. Additionally we have changed the colors of the backgrounds to demonstrate that the presentation is less important than the data provided. Key concepts for evaluating ventilator screens are as follows 1. The values set by clinicians are found on the bottom of the screen. The patient s response is located at the top of the screen. 2. Data are provided in both numerical and graphical contexts on the screen. 3. Much like studying EKGs interpreting flow lines simply comes with experience. Unlike EKGs however there are very few variations to know Ventilators provide three types of tracings flow pressure and volume. Some mechanical ventilators show all three while other brands allow the Springer Nature Switzerland AG 2019 S. R. Wilcox et al. Mechanical Ventilation in Emergency Medicine https 978-3-319-98410-0_6 53 54 Chapter 6. Understanding the Ventilator Screen Pressure Flow Volume Figure Typical waveforms for pressure flow and volume are illustrated clinician to choose two tracings to display on the screen. Fortunately all are labeled directly on the ventilator screens. Figure illustrates typical pressure flow and volume waveforms on a ventilator screen. Please also refer the theoretical illustration of Fig. highlighting the relationship between the volume flow and pressure. Examine the image of the mechanical ventilator .
