The flow rate capacity for a 14 gauge needle is:

The flow rate capacity for a 14 gauge needle is considered to be greater than 450 Blood Flow Rate (BFR). This high flow rate is due to the larger internal diameter of the 14 gauge needle, which allows for a more significant volume of fluid, in this case, blood, to pass through in a given amount of time.

In the context of medical procedures, a higher flow rate is crucial for efficient blood access during dialysis, as it ensures that adequate blood volume can be effectively processed. The use of a 14 gauge needle typically indicates a need for rapid blood flow, especially when there are patient-specific considerations, such as larger body size or higher overall blood volume, that necessitate quick and efficient treatment.

The other ranges refer to flow rates associated with needles of smaller gauges, which would not provide the necessary capacity for procedures requiring a high blood flow rate.
