1. However, elastance does still see some usage by theoretical writers. 2. The tidal volume varies depending on the resistance and elastance of the respiratory system. 3. The total elastance is simply the sum of the individual elastances in that case. 4. The total elastance is simply the sum of the individual elastances in that case. 5. Elastance is also used in microwave engineering.6. One advantage is that an increase in elastance increases loop matrix "'A " ', 7. This expression would be significantly more complicated if Cauer had tried to use a matrix of capacitances instead of elastances . 8. The slope of the voltage-stored charge curve is called " differential elastance " in this field. 9. The term " elastance " was coined by Oliver Heaviside through the analogy of a capacitor as a spring. 10. The slope of ESPVR ( Ees ) represents the end-systolic elastance , which provides an index of myocardial contractility.
