iRealRESP Respiration Technology

Overview

iRealRESP™ is a high-sensitivity respiratory detection technology with impedance sensitivity reaching 0.3 ohms. It integrates advanced algorithms for accurate respiratory rate calculation, cardiac interference suppression, and motion drift compensation, ensuring waveform stability and reliable measurement. Proven in diverse clinical settings, iRealRESP™ demonstrates strong adaptability in emergency care, critical care, and continuous bedside monitoring.

Measurement TheoryAs illustrated, the left diagram demonstrates Lead I-based respiration detection, while the right shows Lead II-based respiration.During respiration, thoracic movements lead to changes in chest impedance between two ECG electrodes. iRealRESP™ applies a constant current through these electrodes, capturing the resulting impedance variations. These changes generate a respiratory waveform, which the system uses to accurately calculate respiratory rate based on the waveform cycle. This method ensures stable and reliable respiratory monitoring across a range of clinical conditions.

Advantages

• High Accuracy

With its Advanced Respiratory Rate Algorithm, iRealRESP™ utilizes a dual-buffer algorithm to ensure accurate and stable respiratory rate (RR) monitoring. One buffer continuously evaluates respiratory cycles to detect abnormalities—such as abrupt changes or excessively slow rates—and adaptively filters out irregular data. Simultaneously, a second buffer supports real-time RR calculation, enabling up-to-date readings while minimizing interference. This dual approach ensures both accuracy and reliability in clinical environments.

• Rapid Recovery Technology for Respiratory Waveforms

1. Implementation Plan

Through integrated hardware and software design, iRealRESP™ incorporates a rapid recovery mechanism to correct motion-induced waveform drift. When deviations exceed a predefined threshold, the system engages hardware-level signal clamping and software-based high-pass filtering to quickly restore waveform integrity, maintaining accurate respiratory rate tracking.

Electrosurgical interference may cause significant respiratory waveform drift; however, iRealRESP™ ensures rapid waveform recovery immediately after the interference ceased, maintaining accurate respiratory monitoring.

2. Clinical Benefits

This technology ensures stable respiratory waveforms, fast recovery from motion artifacts, and improved reliability in RR measurement. Clinical data indicates a 20% reduction in complaints related to unreliable respiratory rate readings, reinforcing its effectiveness in practical use.

Anti-Cardiac Interference Algorithm

• Implementation Plan:

The iRealRESP™ technology integrates an adaptive filtering algorithm designed to eliminate cardiac interference from respiratory signals. By using ECG signals as synchronized reference inputs for real-time adaptive filtering, the system effectively suppresses cardiac-related artifacts, ensuring a clean and accurate respiratory waveform.

• Clinical Benefits:

In patients with strong cardiac signal interference, respiratory rate measurements can be skewed —often incorrectly approaching the heart rate. By removing cardiac interference, iRealRESP™ significantly improves the accuracy and reliability of respiratory rate calculation, especially in critical care settings.
