Patient-Ventilator Asynchrony Incidence

Greater than 10% of total breaths

The incidence of patient-ventilator asynchrony is influenced by the definition of asynchrony, patient condition, ventilator mode, and method of observation.

INCIDENCE OF ASYNCRONY BY CONDITION AND MODE MEASURED IN PERCENTAGE OF PATIENTS WITH ASYNCHRONY IN GREATER THAN 10% OF TOTAL BREATHS
CITATION NUMBER OF PARTICIPANTS CONDITION MODE % OF PATIENTS WITH ASYNCHRONY INDEX* > 10
BLANCH 20151 50 ICU Invasive Ventilation > 24 hrs PCV, PSV, VCV 12
CARLUCCI 20132 69 ICU Invasive Ventilation > 24 hrs NIV, PSV 30
ROBINSON 20133 35 Trauma SIMV, PSV 25.7
VIGNAUX 20094 60 Acute respiratory failure (acute chronic respiratory failure, pneumonia, post-extubation, pulmonary edema, postoperative, thoracic trauma) NIV mode - ICU Ventilator 43
VIGNAUX 20105 65 Acute respiratory failure (acute episode of chronic pulmonary disease, NIV after extubation, pneumonia, post-operative, pulmonary edema) NIV mode - ICU Ventilator 38
THILLE 20066 62 ICU Invasive Ventilation > 24 hrs ACV, PSV 24

*Asynchrony Index (expressed in percentage) = number of asynchrony events/total respiratory rate (ventilator cycles +wasted efforts)×100

ACRONYMS
ACV Assist-control Ventilation
NIV Non-invasive Ventilation
PCV Pressure-control Ventilation
PSV Pressure-support Ventilation
VCV Volume-control Ventilation
