Each pump does have a bolus rate. They are unique and significantly different. The Dana pump by Sooil (South Korean pump manufacturer) is the only device that allows the user to configure rate of bolus flow. The Sooil sales rep told me that slower bolusing leads to less tissue damage. (I've not heard this seconded, though seems plausible.) Each pump does have a different rate of bolus delivery. @jebeck do you know if any devices output the start and end times for a normal bolus?
