Clinical Studies

Decreasing Operating Room Pressure Injuries

AORN Global Surgical Conference & Expo New Orleans, LA, March 24 – 28, 2018.

This study examines the effectiveness of the alternating pressure surface system placed on a standard operating room table in preventing peri-operative pressure injuries among neurosurgical patients.

Sacral skin blood flow response to alternating pressure operating room overlay

AORN Global Surgical Conference & Expo New Orleans, LA, March 24 – 28, 2018.

Of the 1.6 million pressure injuries that develop in acute care settings annually, approximately 25% are acquired intra-operatively during surgeries that last more than three hours. Prolonged ischemia may be one of the factors increasing risk. Alternating pressure (AP) has been shown to increase skin blood flow (SBF) in a controlled laboratory protocol.

Piloting an Alternating Pressure Overlay to Mitigate Pressure Injury.

AORN Global Surgical Conference and Expo, Boston, MA, April 1-5, 2017.

The presence or absence of a pressure injury is a nurse sensitive indicator and reflective of quality nursing care. The patient in the head and neck perioperative setting is at risk for the development of pressure injuries due to inherent risk factors associated with surgery. Comparison of current practice, best evidence-based practice, and assessment of the head/neck surgical population identified the need for increased vigilance and new pressure injury prevention strategies.

Implementation of a Low-Profile MicroPressure Support Surface for the Prevention of Perioperative Pressure Ulcers in Cardiac Surgery Patients

Symposium on Advanced Wound Care, Las Vegas, NV, October 20-22, 2017.

Patients undergoing cardiac surgery are at increased risk for developing perioperative pressure injuries, with reported incidence of up to 29.5%.1 A low-profile alternating pressure (AP) micropressure support surface with hundreds of comfort nodes, designed to periodically off-load static tissue pressure and minimize shear stress during surgery, was evaluated. The device was recently employed for cardiac operations in a large tertiary care center, and its effect on rates of perioperative pressure injuries was studied.

Improving Patient Comfort and Satisfaction in Emergency Departments with a MicroPressure Overlay

Symposium on Advanced Wound Care, Las Vegas, NV, October 7-9, 2016.

To evaluate the effectiveness of a MicroPressure overlay placed over static foam stretcher pads in improving patient comfort and reduce risk of pressure injury development during extended wait periods in crowded Emergency Departments.

Preventing peri-operative pressure ulcers – evaluation of a sacral dressing and an active overlay.

Symposium on Advanced Wound Care, Las Vegas, NV, October 7-9, 2016.

Evaluating the effectiveness of alternating pressure overlay in off-loading body areas at high risk for pressure ulcer during surgeries when used over various types of operating room table pads and in conjunction with sacral dressing.

Preventing pressure injuries in vulnerable nursing home residents using a dynamic overlay: A pilot study

Symposium on Advanced Wound Care, Las Vegas, NV, October 7-9, 2016.

Pressure injury incidence rates vary from 2.2% to 23.9% in skilled nursing facilities and nursing homes. Patients from a nursing home are more than five times more likely to have a pressure ulcer on admission to the hospital than other patients. This study evaluates the effectiveness of an alternating pressure overlay when placed over static foam mattress to prevent pressure injuries in nursing home residents assessed to be at high risk for developing pressure injuries.

A Novel Alternating Pressure Overlay (APO) for Preventing Pressure Ulcers during Surgeries.

Symposium on Advanced Wound Care, Las Vegas, NV, October 16-18, 2014.

Evaluating the effectiveness of an alternating pressure (AP) overlay in off-loading body areas at high risk for pressure ulcer during surgeries using interface pressure (IP) mapping..

MRI Evaluation of Changes in Deep Tissue Thickness for a Novel Alternating Pressure Overlay (APO)

Symposium on Advanced Wound Care, Las Vegas, NV, October 16-18, 2014.

Understanding the interaction between the various types of support surfaces and the physiological changes taking place in the deep tissues is important to effectively evaluate support surfaces.
