Background and Purpose Sequential compression is used to manage lymphedema, but little is known about pressures delivered to the therapeutic targets. This study characterized actual pressures delivered by a traditional compression pump (Lympha Press [LP]) and one using an alternate compression pattern (Flexitouch [FT]). Subjects Ten adults who were healthy volunteered to participate in the study. Methods Pressure-time along the forearm was measured using a 256-pressure sensor array during the pressure cycling of each device. Device assessments were separated by at least 48 hours. Results Pressure patterns and magnitudes produced by the 2 devices differed considerably. The FT pressure pattern displayed a rapid rise and fall, progressing from the wrist toward the elbow. The LP pressure rose slower and was sustained at a higher level during its inflation cycle. Pressures delivered with the LP were significantly greater than those delivered with the FT. Discussion and Conclusion The pressure patterns and magnitudes on treated limbs depend on the device. These differences should be considered before selecting a device for a specific patient.
