[{"type":"text","content":" NEUCHATEL, Switzerland--(BUSINESS WIRE)--\nMasimo (NASDAQ: MASI) today announced the findings of an observational, retrospective study published in Pediatrics International. In the study, researchers at the Osaka Women’s and Children’s Hospital in Japan found the Masimo EMMA® Portable Capnograph “useful for assessment of the respiratory condition in children with tracheostomy.”1 EMMA® provides seamless mainstream capnography for patients of all ages in a compact, easily portable device. The device requires no routine calibration and minimal warm-up time, with accurate end-tidal carbon dioxide (EtCO2) and respiration rate measurements and continuous EtCO2 waveforms displayed within 15 seconds.\nThis press release features multimedia.

Although partial pressure of arterial carbon dioxide (PaCO2) is considered a gold standard for assessing respiratory condition, the researchers chose PvCO2 because “collection of arterial samples is more invasive than collection of venous samples” and noted that studies have shown a correlation between PaCO2 and PvCO2.2,3 They enrolled 9 infants (median age 8 months) and compared 43 paired EtCO2-PvCO2 readings in total.\n\nThe researchers found a correlation coefficient of 0.87 (95% confidence interval of 0.7 – 0.93; p \nThey also found that the median difference in values was significantly greater for readings collected while patients were on mechanical ventilation (28 of the 43 data pairs). With a ventilator, there was a median 11.2 mmHg (6.8 – 14.3) difference; without a ventilator, there was a median 6.6 mmHg (4.1 – 9.0) difference (p = 0.043). The researchers noted that use of a ventilator was significantly related to the difference in paired readings becau...
