True or False: Warming a puncture site can help increase blood flow by 7 times.

Warming a puncture site is known to enhance blood flow significantly due to the dilation of blood vessels in the area. By applying heat, you can increase circulation, which in turn can facilitate blood collection by providing easier access to veins. Research demonstrates that warming can increase blood flow up to seven times, making it a practical technique for medical laboratory procedures, especially when dealing with difficult draws or ensuring a sufficient sample volume.

Although there are nuances regarding the demographics (e.g., adults versus pediatric populations) and sample types, the statement specifically addresses the general effect of warming a site, thereby supporting the assertion that it boosts blood flow by a considerable margin.
