[Graphical monitoring of the artificial lung ventilation. Part 1. Graphs of gas pressure and flow rate during respiration cycle. Capnogram].
Graphical monitoring of the state of the system patient-apparatus for artificial lung ventilation (MLV) provides instant and illustrative information about the state of the system, which is particularly important under conditions of resuscitation and intensive care. Graphs of time dependence of gas pressure in respiratory pathways, gas flow rate, and changes of lung volume during respiration cycle provide on-line information about ventilation mode and patient state including lungs, respiratory pathways, positive pressure at the end of exhalation, etc. These curves allow MLV efficacy to be monitored and improved. Under certain conditions the capnogram shape provides an opportunity for objective evaluation of ventilation adequacy and patient state. The shapes of the curves in the norm and various pathology are considered. This graphical information is concluded to be important for effective use of modern MLV apparatuses for intensive care and resuscitation.
