Insights
Static air-filled surfaces effectively reduce tissue interface pressures in children compared to standard hospital surfaces. This finding is crucial for preventing pressure injuries in pediatric patients.
Area of Science:
- Pediatric medical devices
- Biomedical engineering
- Clinical research
Background:
- Pressure redistributing surfaces are essential for preventing tissue damage.
- Limited research exists on the effectiveness of these surfaces in pediatric populations.
- Identifying optimal surfaces is critical for infant and child care.
Purpose of the Study:
- To determine the most effective pressure redistributing surface for children.
- To compare the efficacy of static air-filled surfaces against standard hospital surfaces.
Main Methods:
- A repeated measures design was employed, with each child serving as their own control.
- 49 infants and children participated across two academic medical centers.
- A pressure mapping system quantified interface pressures and surface areas.
Main Results:
- Static air-filled surfaces demonstrated a lower mean pressure (10.41 mmHg) than regular surfaces (12.43 mmHg).
- Peak pressures were significantly lower on static air surfaces (22.44 mmHg) compared to regular surfaces (34.92 mmHg).
- Static air surfaces provided a larger contact area (140.1 sq inches) than regular surfaces (105.3 sq inches).
Conclusions:
- Static air-filled surfaces significantly reduce tissue interface pressures in children.
- These surfaces offer a promising solution for pressure injury prevention in pediatric care.
- Further research may explore long-term outcomes and diverse pediatric populations.
Purpose:
The purpose of this study was to identify the most effective pressure redistributing surface in children.
Design:
Repeated measures design study with each participant acting as their own control.
Subjects And Setting:
The sample comprised 49 infants and children; their mean age was 4.5 (SD: 5.2) months. Their average weight was 9.56 (SD: 8.6) kg. The study setting was conducted at two academic medical centers in the western United States: University of California Davis Health and University of California, San Francisco Children's Hospitals.
Methods:
A pressure mapping system was used to measure interface pressures and surface areas between the surface and body of study participants. We compared pressures from a standard hospital bed, crib, or isolette surface used in the respective hospitals to a static air-inflated surface placed on top of the standard surface.
Results:
The mean pressure for static air-filled cushions was 10.41 mmHg, with peak pressure of 22.44 mmHg, while regular cushions had a mean pressure of 12.43 mmHg and peak pressure of 34.92 mmHg. The average surface area for the static air surfaces was 140.1 sq inches and the average surface area for regular surface was 105.3 sq inches.
Conclusions:
Static air-filled surfaces had lower tissue interface pressures when compared to standard hospital surfaces.

Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
