Clinical Evaluation of the CM-1500 in Postoperative Surgery Patients

Zynex Monitoring Solutions200 enrolled

Overview

The primary objective is to evaluate the the changes in the Relative Index in post abdominal or pelvic surgery patients on the Cardiac Monitor Model CM-1500.

Postoperative hemorrhage incidence can vary depending on the type of surgery, but it can lead to severe clinical complications ranging from mild anemia to fatal hemorrhagic shock. Monitoring and detecting these fluid changes postoperatively can be complicated, and standard operating procedures vary. The Cardiac Monitor, Model 1500 (CM-1500), uses a personalized approach by non-invasively and simultaneously monitoring five (5) physiological parameters.

Relative Index Change During PACU Stay

The primary objective is to evaluate changes in the Relative Index (RI) in post-abdominal or pelvic surgery patients (Laparoscopic or Open). The CM-1500 monitors parameters which are indicative of relative changes in fluid volume in adult patients. The Relative Index is an investigational value which utilizes proprietary algorithms to combine the relative changes of each measured parameter into a single value. The Relative Index is graded on a scale where 100 indicates a patient's baseline, and changes up or down from the baseline could be used as potential indicators of fluid gain or loss relative to the baseline, based on the changes of the individually monitored parameters. Per the device's FDA 510(k) clearance, the RI is computed as the weighted summation of the percent change values (signifying the deviation of each parameter from it's baseline value) for its parameters. Change in RI is calculated by subtracting the initial RI value from the final RI value during monitoring.

Time frame: Length of PACU Stay (Range: 46 to 353 minutes)
