Alarm Management Features for Pulse Oximetry Monitoring

Nellcor™ SatSeconds

SatSeconds analyzes desaturation events by multiplying their duration, in seconds, by the number of percentage points the patient drops below the SpO2 alarm limit. As a safety precaution, when three or more SpO2 alarm violations occur within 60 seconds, an alarm will sound even if the SatSeconds limit has not been reached.

LoSat Expanded Accuracy

Nellcor™ adhesive sensors with OxiMax™ technology and LoSat Expanded Accuracy range give clinicians the ability to assess patients with critically low saturation readings (60%-80%), such as infants with congenital heart disease. Accurate readings at low saturation levels expand options for clinicians to effectively monitor pulse oximetry.([FOOTNOTE=Bebout DE, Mannheimer PD, Wun C-C. Site-dependent differences in the time to detect changes in saturation during low perfusion.Crit Care Med. 2001;29(12):A115.],[ANCHOR=View Abstract],[LINK=/content/mitg/websites/languagemasters/na/en-us/support/clinical-evidence.html?id=805201])

Alarm Management Features for Capnography Monitoring

Below are several alarm management features for capnography monitoring.


Apnea-Sat Alert (ASA)*

ASA tracks and reports apneas per hour (A/hr), and the oxygen desaturation index (ODI) indicates the ‘dips’ in SpO2 (number of times the SpO2 value dropped 4 percent or more from baseline and returned to baseline in 240 seconds or less). A visual alert appears if the A/hr exceed a preset threshold over user selectable time periods of 2, 4, 8 or 12 hours. A/hr and ODI are displayed in real time on the monitor home screen, and the data is available in trend reports, in print outs and through data export.

ASA trend screen displays an analysis of A/hr by length of the apneas.

*Apnea-Sat Alert is FDA cleared for adults 22 years of age or older.

Smart Breath Detection™ (SBD)

Proprietary filter and pattern recognition algorithm screens out low-amplitude “non-breath” etCOexcursions like snoring, talking or crying, to provide a more accurate respiratory rate.

Smart Alarm for Respiratory Analysis™ (SARA)

Reducing distractions from clinically insignificant alarms helps preserve caregiver alarm vigilance, leading to improved patient safety.([FOOTNOTE=The hazards of alarm overload. Keeping excessive physiologic monitoring alarms from impeding care. Health Devices. 2007;36(3):73-83.],[ANCHOR=View Abstract],[LINK=/content/mitg/websites/languagemasters/na/en-us/support/clinical-evidence.html?id=603510]) Functioning in combination with the SBD algorithm, the SARA algorithm is proven to reduce clinically insignificant respiratory rate alarms by dynamically adjusting the respiratory rate averaging algorithm during periods of breath-to-breath cycle variability.([FOOTNOTE=Hockman S, Glembot T, Niebel K. Comparison of capnography derived respiratory rate alarm frequency using the SARA algorithm versus an established non-adaptive respiratory rate alarm management algorithm in bariatric surgical patients. [Open forum abstracts] Resp Care. 2009;12.],[ANCHOR=View Abstract],[LINK=/content/mitg/websites/languagemasters/na/en-us/support/clinical-evidence.html?id=603514])

Integrated Pulmonary Index™ (IPI)

IPI incorporates four real-time respiratory measurements into a single number, displayed on a scale from 1 to 10, representing an inclusive respiratory profile. Helpful in busy clinical environments, IPI provides a simple and comprehensive indication of respiratory status and trends, promoting early awareness of changes to a patient’s breathing.

Remote Alarm Management Solutions

Covidien supports a range of remote alarm annunciation connectivity options to help clinicians monitor patients through nurse call systems, stand-alone central stations, wireless phones and pagers.

Vital Sync™ Virtual Patient Monitoring Platform (VPMP)

Vital Sync VPMP offers Electronic Medical Record (EMR) connectivity and remote continuous patient monitoring. Clinicians can remotely view patient information from ventilators, capnography monitors and pulse oximeters on any web-enabled devices. Patient information is sent to the EMR, Clinical Information System, and alarm forwarding systems.
