Medical Ventilators
Breathe Easy with
Sensor-Driven Precision
Medical ventilators support patients unable to breathe independently by delivering precise amounts of air or a mixture of oxygen and air into the lungs. Modern ventilators are sophisticated, electronically controlled devices that regulate airflow and pressure to meet patient needs. As life-critical systems, any malfunction can have severe consequences.
Ventilators are primarily used in hospitals, including during surgery, in intensive care units (ICUs) where patients need continuous monitoring and support, and in emergencies where breathing is compromised due to illness, injury, or medical conditions. With technological advancements, portable and home-use ventilators have become increasingly common, allowing patients with chronic respiratory conditions to receive care outside of a hospital setting. Ventilators are also used in ambulances and during patient transport, ensuring individuals in critical condition receive immediate respiratory support.
Additionally, ventilators are often categorized by patient type, such as adult or neonatal. Neonatal ventilators are designed for newborns and infants, offering lower and more precise ventilation rates to meet their delicate respiratory needs.
Hospitals traditionally used high-pressure, tank-based ventilators, but the trend is shifting toward portable, low-pressure units. Modern portable ventilators use blower mechanisms to generate airflow on demand, similar to a fan. However, the noise produced by these systems can be disruptive, posing a challenge manufacturers need to address to improve performance and comfort.
Unique Capabilities for Ventilators
The NimbleSense architecture was designed to maximize performance while also being flexible to easily insert application specific capabilities. The result is a pressure sensor architecture having a very clear signal and practically no noise, leading to the incredible accuracy, TEB and long-term stability. Specific to ventilators, we have implemented these additional capabilities:
Eliminates oversampling
Eliminates the need to oversample sensor outputs, as the sensor oversamples at 12 kHz and includes internal bandwidth filters providing a clean > 1 kHz data rate
Extreme resolution
Sensors have 24-bit output resolution and include two extreme resolution sensors with approximately 18-bit effective resolution at very high bandwidths
Advanced digital filtering
Multi-order filter that leverages advanced filtering capabilities at the front end of the sub-system to eradicate critical noise caused by fans, blowers, or other sources before they reach the pressure-sensing sub-system
Multi-Range™ technology
A single device can accommodate up to eight different pressure ranges, with each range being factory-calibrated and optimized to maintain consistent total error band, accuracy, and stability
Superior’s NimbleSense architecture enables us to develop unique products optimized for different markets. For the medical ventilator market, we have developed the following products. As our architecture is very flexible, we can also develop custom solutions for your specific application.
