M1174442-S1 Differential Pressure Flow Sensor Respiratory Flow

M1174442-S1 Differential Pressure Flow Sensor Respiratory Flow

Core Features
1. Measures bidirectional airflow (inhalation/exhalation) within the breathing circuit, and calculates tidal volume, minute ventilation, and flow waveforms.
2. Operates based on the differential pressure principle: airflow passing through a restriction orifice generates a pressure differential, which the sensor converts into an electrical signal for processing by the host unit.
3. Consists of the sensor body plus a connecting tube; features plug-and-play functionality and is reusable after high-temperature sterilization.

Common Applications and Faults
1. Application Scenarios: Monitoring of respiratory airflow in anesthesia machines within operating rooms and ventilators within ICUs (GE HealthCare).
2. Typical Faults: Significant deviations in tidal volume, abnormal airflow waveforms, or circuit leak failures during self-tests. These issues are primarily caused by sensor aging or contamination, necessitating cleaning or replacement.
3. Installation Guidelines: Observe the correct airflow direction; perform regular cleaning; and prevent contamination of the sensor ports by moisture or secretions.
