“…Careful examination of chest movement is important in upper GI endoscopy as end tidal CO 2 is unreliable in this setting. [3] Special attention was paid to the pulse oximeter derived plethysmograph. Non-invasive blood pressure (NIBP) at 2-3 min interval was recorded when pulsatility was present on plethysmograph.…”

“…In another study performed during gastrointestinal endoscopy in patients under general anaesthesia [12], bias (limit of agreement) for respiratory rate measurement was 0.0 (2.0) bpm for acoustic monitoring and 0.4 (11.8) bpm for thoracic impedance, when compared with capnometry. The performance of the acoustic method has also been compared with capnometry using a nasal cannula.…”

SummaryRespiratory depression, a potentially serious complication after general anaesthesia, can be detected promptly by close monitoring of both oxygen saturation and respiratory rate. Obese patients have morphological changes that may impair the reliability of monitoring devices. In this study, respiration rate was simultaneously recorded every second for up to 60 min using a computer in 30 adult obese patients (body mass index ≥ 35 kg.m À2 ), by three methods: acoustic; thoracic impedance; and capnometry via a facemask (Capnomask â , reference method). Of the 99 771 data triplets collected, only 85 520 (86%) were included; 12 021 (84%) were not studied due to failure of capnometry and 2240 (16%) due to failure of the acoustic method. Compared with capnometry, bias was similar using both the acoustic method and impedance (À0.3 bpm vs À0.6 bpm, respectively, p = 0.09), but limits of agreement were narrower for the acoustic method (AE3.5 bpm vs AE5.3 bpm, respectively, p = 0.0008). The proportion of respiration rate values obtained with the acoustic method and impedance that differed by at least 10% or 20% for more than 15 s were 11% vs 23% and 2% vs 6%, respectively (p = 0.0009 for both comparisons). The acoustic sensor was well tolerated, while the facemask was pulled off on several occasions by four (13%) agitated patients. In obese patients requiring close monitoring of respiration rate, the acoustic method may be more precise than thoracic impedance and better tolerated than capnometry with a facemask.

“…It occurs when patients removed the facemask [2,5]. And it occurs at mouth breathing, under respiratory monitoring by capnography coupled with a nasal cannula [7]. In comparison between normality widely used methods (capnography and pneumotachograph) under airway management, normality widely used methods is useful than acoustic monitor for continuous monitoring of respiratory rate for general anesthesia with airway management.…”

A new acoustic method for Respiratory Rate Monitoring (RRa ® ) has shown good reliability when used in patients without tracheal intubation. The objective of this review is to assess the usefulness of acoustic respiratory rate monitoring. In contrast to facemask capnometry, the acoustic monitor was well tolerated; contrary, capnometry was not well tolerated, because several patients removed the facemask. In intravenous general anesthesia, the acoustic monitor is useful for continuous monitoring of respiratory rate in spontaneously breathing patients. In pediatric patients, acoustic monitor showed good agreement and similar accuracy and precision between capnometry but was better tolerated.In conclusion, the acoustic respiratory monitoring is useful for non-intubated patients.
