Philips BIS M1034A measurement module: an essential tool for real-time consciousness monitoring
The Philips BIS M1034A module represents a major advance in anaesthesia and sedation management, providing objective and continuous measurement of consciousness using Bispectral Index (BIS®) technology. This technology converts electroencephalographic (EEG) activity into a numerical value ranging from 0 (no brain activity) to 100 (full consciousness), allowing healthcare professionals to precisely tailor the dosage of sedatives or anaesthetics to the specific needs of each patient.
Using Aspect Medical Systems' XP platform, this module integrates via the BISx Power Link™ system, a compact and portable interface that simplifies connection to compatible Philips monitors. It provides a range of essential indicators such as the BIS index, electromyographic (EMG) strength, signal quality index, suppression ratio, EEG waveform, total power, spectral frequency (SEF) and burst rate — parameters that are essential for a comprehensive assessment of sedation depth.
Its robust design and resistance to electrosurgical interference make the M1034A a reliable module even in technically demanding environments such as operating theatres. Electromyography-related artefacts are effectively detected and filtered out by the integrated algorithm, ensuring the reliability of the displayed measurements.
The module is equally valuable in intensive care units (ICUs). It allows the monitoring of the level of consciousness of patients under mechanical ventilation, barbiturates, neuromuscular paralysis or during bedside procedures. BIS monitoring has been shown to reduce the risk of unpleasant postoperative memories while facilitating ventilatory weaning.
Its value is also recognised in complex clinical cases: elderly, paediatric and frail patients, or those requiring lengthy procedures. With the BIS M1034A module, clinicians have a reliable decision-making tool that takes into account individual variability in responses to anaesthesia, thereby limiting overdoses and side effects such as nausea or post-operative disorientation.
The module is compatible with a wide range of sensors — suitable for diverse clinical profiles — and offers great flexibility in displaying data on the screen, according to the preferences of the caregiver and the requirements of the patient. Compact and easy to install, it optimises hospital workflow while contributing to precision medicine centred on the patient.
