Why Wearing Optimisation Is Essential Before Monitoring with CardioWatch 287-2
Before initiating continuous patient monitoring with the Corsano CardioWatch 287-2, it is crucial to perform the Wearing Optimisation procedure. This short procedure — where the patient is asked to sit still or lie down for approximately one minute — ensures the device can determine the optimal LED power settings for that individual.
Purpose of Wearing Optimisation
The Corsano CardioWatch uses photoplethysmography (PPG) to measure physiological signals such as SpO₂. The accuracy of these measurements is highly dependent on how well the emitted light penetrates the skin and reflects back to the sensor. Factors like:
- Skin pigmentation
- Hair density
- Tissue composition (e.g., muscle tension, BMI)
- Wrist curvature and fit
all influence the quality of the optical signal.
Benefits of the Optimisation Step
- Maximizes signal quality: Automatically adjusts LED intensity to match the patient’s unique physiological characteristics.
- Improves measurement accuracy: Especially important for SpO₂, where incorrect power levels can lead to inaccurate readings.
- Reduces artefacts and noise: Helps prevent false alarms and improves reliability of continuous monitoring.
- Ensures consistent performance: Particularly in diverse patient populations with varying skin tones and anatomical differences.
Clinical Relevance
Inaccurate SpO₂ readings can lead to inappropriate clinical decisions. By conducting the Wearing Optimisation, healthcare professionals ensure that the device is calibrated for each patient, providing clinically valid and trustworthy data from the start of monitoring.
