Pressure instability in medical devices is rarely the result of a single failure. More often, it develops gradually through design decisions, component selection, and operating conditions that introduce variability over time.
In systems such as ventilators, anesthesia delivery equipment, and sterilizers, stable pressure control is essential to performance and safety. Even small fluctuations can affect dosing accuracy, process consistency, or system responsiveness. While many components meet initial specifications, long-term stability depends on how those components behave after repeated cycling, cleaning, and continuous use.
Material compatibility is one common factor. Exposure to cleaning agents, temperature changes, or steam can alter component behavior if materials are not selected specifically for medical environments. Over time, this can lead to drift, leakage, or inconsistent response.
Mechanical design also plays a role. Complex assemblies with multiple wear points are more likely to introduce variation as components age. In contrast, simpler, proven designs tend to maintain repeatable performance across high-cycle medical applications.
Integration is another often-overlooked contributor. Components that are difficult to install or poorly matched to the surrounding system can introduce stress, misalignment, or inconsistent loading, all of which can impact pressure stability once deployed.
Marsh Medical works with OEM teams to address these factors early in the design process. By focusing on material stability, proven mechanical designs, and integration-ready components, Marsh Medical helps manufacturers reduce pressure variability and support consistent performance over the life of the device.
In medical systems where reliability is critical, pressure stability is not something to troubleshoot after launch. It is a design outcome that must be engineered from the start.
