Patient SafetyNet Remote Monitoring

Keep Patients Safe When Administering Opioids

In August 2012, The Joint Commission issued a Sentinel Event Alert on the safe use of opioids in hospitals and recommended continuous oxygenation and ventilation monitoring.1 With Masimo Patient SafetyNet*, you can rest easier knowing accurate alarms from Masimo SET® pulse oximetry are instantly sent to assigned clinicians through an easy-to-use, flexible, and cost-effective monitoring system.

Patient SafetyNet and Masimo SET® enabled Dartmouth-Hitchcock Medical Center to significantly improve clinical outcomes and reduce the cost of care.2,3

For post-surgical ventilation monitoring, Patient SafetyNet is available with standard capnography or with rainbow Acoustic Monitoring™ which utilizes a noninvasive acoustic sensor to measure respiration rate continuously. In a recent study, rainbow Acoustic Monitoring™ had a higher sensitivity than standard capnography to detect pauses in breathing.4

Patient SafetyNet Connects Patients and Caregivers Quickly, Easily, and Accurately

Masimo Patient SafetyNet* remote monitoring and clinician notification system combines the performance of Masimo SET® pulse oximetry with ventilation monitoring and wireless clinician notification via pager or 3rd party gateway to IP phones. Patient SafetyNet provides an unmatched level of patient safety on the general floor in a system that can either be integrated into either your existing wired or wireless network.

Facilitating appropriate early clinical response, preemptions of sentinel events, and avoidance of unnecessary transfers while helping you meet The Joint Commission1, Institute for Safe Medication Practices (ISMP)5, Anesthesia Patient Safety Foundation (APSF)3, and American Society of Anesthesiologists (ASA) guidelines.6

Overview and Clinical Benefits

Clinical Flexibility

Configurable screens allow you to view the number of patients, clinical measurements, and level of detail that are important to you

With Patient SafetyNet, you choose the system configurations that meet your specific clinical need. You can display real-time data from up to 40 patients at a time and select up to four parameters based on your patient population and clinical practices.

individual patientsParameter View: View up to four parameter value s and alarm status of all patients at a glance

Trend View: Review up to 96 hours of history from all monitored parameters with an easy-to-use touchscreen

Trend View: Review up to 96 hours of history from all monitored parameters with an easy-to-use touchscreen

Powerful Information

Powerful Information to Manage Patients, Optimize Workflow, and Assess IT Infrastructure

Flexible and convenient access with the ability to generate and print reports from any hospital computer, eliminating the need to download data directly from the bedside device.

> Patient Report – Improve clinical workflow by optimizing alarms and notification settings
> System Report – Summarizes system level events
> Patient Trend Analysis Report – Evaluate historical trend data to determine additional diagnostic needs (example below)

Data like respiration rate and oximetry can prove to be valuable tools in understanding whether a patient’s respiration patterns indicate previously undetected issues, especially during sleep.

“One unanticipated effect is new diagnoses identified by the system. Many obstructive respiration patterns, likely undiagnosed sleep apnea, have caused repeated alarms at night and led to increased collaboration with the on-site sleep lab.”1

Enabling Technology

Masimo SET® Pulse Oximetry

The accuracy and reliability of Masimo SET® significantly reduces false alarms and makes accurate clinician notification on the general floor possible

When identifying general floor monitoring solutions some hospitals look to scale their telemetry system to the general floor. However ECG telemetry is not optimal for monitoring non-cardiac post-surgical patients because:

  1. The high alarm rate of ECG monitoring is not acceptable for the General Floor
  2. ECG methods for measuring respiration rate are limited in their ability to detect apnea
  3. ECG monitoring requires a dedicated monitor technician or nurse
Oxygenation monitoring, as recommended by both The Joint Commission and Anesthesia Patient Safety Foundation, provides an earlier indication of respiratory depression. Given nurse-to-patient ratios, patient ambulation, and rising patient acuity on the general floor, the chosen pulse oximetry technology must be able to measure through challenging conditions while minimizing false alarms. Masimo SET® is the best pulse oximetry choice for patient safety, clinical efficacy, and cost effectiveness.1

True and False Alarm Rates During Challenging Conditions

true and false

In this hospital-based study, investigators measured SpO2 in 10 subjects during motion and low perfusion conditions and calculated the false alarm rate during 120 full oxygenation events (specificity) and true alarm rate during 40 de-oxygenated events (sensitivity).2

Evidence-Based Alarm Management

> Earlier alarm notification without extending averaging times during challenging conditions like the Nellcor N-600
> Alarm reports enable evidence-based settings to titrate alarm frequency to acceptable levels for
general floor clinicians
> Configure alarm rules remotely or at the bedside to provide maximum clinical flexibility

Value of Patient SafetyNet

Proven to Help Improve Clinical Outcomes3

Since Patient SafetyNet was instituted on a postsurigcal orthopedic unit at Dartmouth Hitchcock Medical Center in 2007, there have been no patients that have suffered irreversible severe brain damage or death as a result of respiratory depression from opioids. In their initial 11 month evaluation of Patient SafetyNet on a single 36-bed orthopedic postsurgical unit, they demonstrated significant reductions in rapid response team activations and ICU transfers:3
