Airway management

Airway management is the process of ensuring that there is an open pathway between a patient’s lungs and the outside world, and that the lungs are safe from aspiration

Apnea Index (AI)

Number of cessations of breathing of 10 seconds or more that have occurred per hour

Arterial to End Tidal CO2 Gradient

The relationship between arterial and end-tidal partial pressure of carbon dioxide: P(a-et)CO2

TopC

Capnograph

Instrument used to measure the CO2 concentration in an air sample. Produces both waveforms and numeric values of the patient's exhaled breath and are used to identify adverse ventilation events

Capnography

Non-invasive method for monitoring the level of carbon dioxide (CO2) in exhaled breath (etCO2) to assess a patient's ventilatory status

Capnostream™20

Oridion portable bedside Microstream capnograph that enables effective, proven airway management by providing the earliest indication of airway compromise

COPD

Chronic Obstructive Pulmonary Disease

TopE

EMS

Emergency Medical Services

etCO2

end tidal CO2; end of expiration. Normal values of etCO2 are 35-45 mmHg

TopF

FiCO2

Fractional concentration of inspired CO2

FilterLine®

Oridion single patient CO2 breath sampling accessories used with Microstream® capnography enabled monitors. Include normal and high humidity sampling lines for intubated and non-intubated patients, oral/nasal sampling and oxygen delivery

TopI

IPI (Integrated Pulmonary Index™)

IPI helps caregivers manage four complicated monitoring parameters (etCO2, RR, PR and SpO2) with a single number to provide an uncomplicated, inclusive assessment of a patient’s ventilatory status

TopM

MCS™ (Molecular Correlation Spectroscopy™)

A laser-based technology used to increase the accuracy and reliability of capnography monitoring. With lock and key precision, MCS creates an infrared emission that precisely matches the absorption spectrum of CO2

Microcap®

Portable capnograph measuring etC02 and respiration rate

Microcap® Plus

Portable capnograph measuring etC02 and SpO2 (Microstream® capnography and Nellcor pulse oximetry)

Microstream®

CO2 specific measuring technology based on MCS that provides the most specific etC02 detection of any capnography technology

TopO

Omnistream™

Omnistream product family includes CO2 sampling lines for use in all hospital and pre-hospital areas. Omnistream products are compatible with most types of (non-Microstream®) sidestream CO2 monitors including General Electric, Datex-Ohmeda, Welch Allyn & Spacelabs

Oxygen Desaturation Index (ODI)

Number of times per hour that the SpO2 goes 4% or lower from baseline and returns to baseline in 240 seconds or less

TopP

PaCO2

Partial pressure of CO2 in arterial blood

PCA

Patient-controlled analgesia

PETCO2

Partial pressure of CO2 at the end of expiration

Pulse oximetry

Non-invasive method allowing the monitoring of the oxygenation of a patient’s hemoglobin

TopS

Safe Sedation

Web-based data repository available to all healthcare professionals at www.SafeSedation.org. Used to track procedural sedation metrics required by the Joint Commission

SARA™ (Smart Alarm for Respiratory Analysis™)

SARA is an alarm management technology that recognizes and reduces clinically insignificant respiratory rate alarms while accurately reflecting the patient’s condition and preserving caregiver alarm vigilance

Smart BDA™ (Smart Breath Detection Algorithm™)

Algorithm that rejects shallow, non-breath CO2 excursions from being counted as breaths. The Smart BDA suite of proprietary filter and pattern recognition techniques screens out the low amplitude CO2 changes superimposed on the etCO2 waveform

Smart CapnoBloc™

Sampling system to facilitate continuous CO2 monitoring and oxygen delivery during upper endoscopy procedures

Smart Capnography™

Smart Capnography is a family of superior algorithms that reduce alarms, improve workflow and provide clinical utility for improved patient safety. Smart Capnography includes the Smart BDA, SARA, IPI and SSDx

SpO2

Saturation of O2 in the arterial blood (%)

SSDx (Smart Sleep Breathing Disorder Diagnosis™)

An algorithm developed by Oridion that reports apnea and oxygen desaturation events and calculates the associated apnea index (AI) and oxygenation desaturation index (ODI) for adult and pediatric patients

Surestream™

Surestream CO2 sampling lines are a combination of Oridion and Welch Allyn monitoring technologies for use with intubated and non-intubated patients

TopU

Uni-junction™

FilterLine feature, enables sampling from either the mouth or the nose, patented design permits upward or downward pressure of the breath at the junction, allowing only that source of breath (with the greatest pressure) to be sampled
