Masimo touts data from acoustic respiration rate trial

Masimo (NSDQ:MASI) yesterday released data from a study comparing the company’s Masimo acoustic respiration rate with its Radical-7 Pulse co-oximeter against Medtronic‘s (NYSE:MDT) Nellcor plethysmographic respiration rate, touting faster detection of respiratory pauses with the Masimo tech. The study, performed at the Tokyo Women’s Medical University, investigated the use of the 2 technologies on 50 adult study volunteers. Respiration rate, pulse rate and oxygen saturation values were measured using the 2 technologies. Both devices were configured to alarm in the event of a respiratory pause or slow respiration rate for 30 seconds, respiration rate under 10 breaths per minute and an SpO2 level of 90% or below, Masimo said. In the study, volunteers were instructed to breathe at a rate of 12 breathes per minute for 3 minutes, then hold their breath until the alarms were triggered. A smaller group of 10 volunteers performed the same procedure with respiratory pause and low respiration rate alarms set to 15 seconds. Results indicated that the Masimo system alarmed 114 times out of 143 procedures, while the Nellcor’s alarm only alerted 15 times. Average time to alarm for the Masimo device was 35 second, versus 59 seconds with the Nellcor. Nellcor alarms were most commonly triggered by SpO2 being below 90%, while Masimo alarms were caused by respiration rate falling below 10 breaths per minute. Of the smaller subgroup which suspended breathing for 15 seco...
