Minimizing Site Reactions Can you minimize site reactions through your choice of supplies? Many patients say yes! Things to keep in mind: • Longer needles often help reduce site reactions; • Go for more sites and less drug per site if you are still having problems; • Inserting dry needles will minimize skin irritation; • Watch out for dressing and tape sensitivities; • Starting with a slower flow rate helps reduce initial local reactions (see tubing chart). Note: Site reactions in new patients usually diminish over time as the sub-q depots become more developed. For more details, see Troubleshooting on page 15. A Balanced Infusion Through DynEQ™ What does DynEQ™ mean for you? DynEQ™ (Dynamic equilibrium) balances your fastest infusion with your most comfortable one. You get to infuse as rapidly as your provider recommends. If the pressure in your site(s) increases, the system immediately responds by automatically slowing down. The pump will maintain a safe pressure of 13.5 psi throughout the infusion (see below). Other pumps, designed for constant flow (such as electronic pumps), respond to tissue saturation by increasing pumping pressure to maintain their programmed flow rate. High pump pressures can cause high pressures within infusion sites, leading to more problems at each site (shown below). 8
