Respiratory Care

Monitoring oxygenation and ventilation throughout the breathing cycle helps provide a more complete picture of a patient's respiratory status.

Oxygenation

Masimo’s breakthrough technology, Signal Extraction Technology^® (SET^®), overcame the limitations of conventional pulse oximetry with the ability to measure through motion and low perfusion. Masimo SET^® is able to recognize that both arterial and venous blood can move, using parallel signal processing engines to separate the true arterial signal from sources of noise, including the venous signal. Multiple studies have demonstrated that Masimo SET^® outperforms conventional pulse oximetry technologies.¹ In one study comparing the ability of three pulse oximetry technologies to detect hypoxic events, Masimo SET^® pulse oximetry demonstrated the highest sensitivity and specificity during induced conditions of motion and low perfusion.²

While Masimo pulse oximeters offer SET^® SpO₂ and pulse rate (PR), among other measurements, Masimo Pulse CO-Oximeters^® offer additional advanced measurements, including total hemoglobin (SpHb^®) and dyshemoglobins, expanding visibility of a patient’s oxygenation status.

Ventilation

Capnography is a noninvasive monitoring technique that allows fast and reliable insight into ventilation, circulation, and metabolism.

In situations requiring intubation, capnography has long played a role in confirming proper endotracheal tube placement and, in both elective and emergency intubations, end-tidal carbon dioxide (EtCO₂) measurement is a standard of care for confirming endotracheal intubation.³ In addition, EtCO₂ provides a noninvasive estimate of the partial pressure of carbon dioxide (PaCO₂) and insight into a patient’s breathing rate and pattern before extubation.³

When used together, capnography and pulse oximetry are useful in weaning patients off mechanical ventilation.⁴ In addition, capnography also facilitates monitoring of spontaneous ventilation after weaning and during sedation procedures.^4,5 A 2017 meta-analysis of sedation-related adverse events found that the inclusion of capnography monitoring resulted in a reduction in respiratory compromise during procedural sedation and analgesia compared to visual assessment and SpO₂ alone.⁶

NomoLine^® Capnography eliminates common problems associated with conventional sidestream gas analysis. Incorporating a unique, patented polymer, NomoLine sampling lines allow water to evaporate into the surrounding air, while leaving oxygen, carbon dioxide, and anesthetic gases unaffected, eliminating the need for a water trap and issues related to their handling. Designed for low-flow applications, with functionality in any orientation, NomoLine sampling lines can be used in a variety of clinical scenarios on both intubated and non-intubated adult, pediatric, infant, and neonatal patients, in both low- and high-humidity applications. 

Innovations in Respiration Rate Monitoring: rainbow Acoustic Monitoring^®

rainbow Acoustic Monitoring provides a noninvasive, continuous, easy-to-use, and reliable monitoring solution that has the benefit of higher patient compliance.^{7, 8} Additionally, continuous monitoring of SpO₂ and acoustic respiration rate (RRa^®), as well as other physiologic parameters, on a single Masimo Pulse CO-Oximeter facilitates well-rounded patient assessment and provides clinicians with more data to make informed care decisions.
