A new noninvasive patient monitor enables clinicians to measure arterial blood pressure (BP), temperature, and other parameters in adult, pediatric, and neonatal patients.

The Masimo (Irvine, CA, USA) Root connectivity and patient monitoring platform enables clinicians to measure arterial BP in a range of patients, with three distinct measurement modes: spot-check, automatic interval, and stat interval. An integrated module from Welch Allyn (Skaneateles Falls, NY, USA) measures temperature. Measurements from the Masimo Radical-7 handheld or Radius-7 patient-worn monitor, including measure-through motion, low perfusion pulse oximetry, continuous hemoglobin (SpHb), Pleth Variability Index (PVI), and other noninvasive rainbow SET parameters can also be displayed.

The Masimo Root offers a high visibility display with intuitive, touch-screen navigation for easy and adaptable use in any hospital environment, and with flexible measurement expansion through Masimo Open Connect (MOC-9) software, including CO2 capnography for sidestream monitoring and O3 regional oximetry for the simultaneous measurement of regional oxygen saturation (rSO2) and arterial oxygen saturation (SpO2). The measurements can help clinicians detect regional hypoxemia that pulse oximetry (SpO2) alone can miss.

Other expansion options include SedLine brain function monitoring, which provides four channels of electroencephalography (EEG) to help clinicians better understand the effects of anesthesia on the brain by measuring the effects of anesthesia and sedation on the brain's electrical activity. The Root also enables to easily and automatically document vital signs data, alarms, and alerts, seamlessly forwarding them to the patient's clinician and document them in the patient's electronic medical record (EMR) via Masimo’s proprietary SafetyNet.

“With the addition of blood pressure monitoring, we can provide patients in sub-acute care an integrated solution that will provide more efficient and effective care for our patients,” said Caroline Stade, Chief Nursing Officer at University Children's Hospital Basel (UKBB; Switzerland). “With remote alarm notification from Patient SafetyNet, we've been able to give proper care to patients in need without the false alarms that made proper care previously untenable.”

Conventional pulse oximetry assumes only arterial blood pulsates at the measurement site. But during patient motion, venous blood also moves, causing conventional pulse oximetry to under-read since it cannot distinguish between the arterial and venous blood. SET signal processing can identify the venous blood signal, isolate it, and use adaptive filters to cancel the noise and extract the arterial signal, thus reporting the true arterial oxygen saturation and pulse rate.
