Model to determine resistance and leakage-dependent flow on flow performance of laparoscopic insufflators to predict gas flow rate of cannulas.
To characterize insufflator CO2 gas flow performance to predict gas flow rate with standard cannulas. ⋯ Gas flow depends not only on maximum flow of insufflators but also on resistance of cannulas and leakage rate. With this model it is possible to predict the real, available flow of insufflator-cannula combinations for the first time. Improved resistance of all components can save insufflation time.
