Multicenter StudyThe ability of a new continuous cardiac output monitor to measure trends in cardiac output following implementation of a patient information calibration and an automated exclusion algorithm.
A new non-invasive continuous cardiac output (esCCO) monitoring system solely utilizing a routine cardiovascular monitor was developed, even though a reference cardiac output (CO) is consistently required. Subsequently, a non-invasive patient information CO calibration together with a new automated exclusion algorithm was implemented in the esCCO system. We evaluated the accuracy and trending ability of the new esCCO system. ⋯ The percentage error was 69.6 %. Polar plots analysis showed that the mean polar angle was -1.6° and radial limits of agreement were ±53.3°. This study demonstrates that the patient information calibration is clinically useful as ICO, but trending ability of the new esCCO system is not clinically acceptable as judged by percentage error and polar plots analysis, even though it's trending ability is comparable with currently available arterial waveform analysis methods.

Airway management practices in adult intensive care units in Israel: a national survey.
Timely and adequate management of normal and compromised airway is a crucial task facing medical teams taking care of patients in intensive care units. We investigated the airway management practices in the Israeli intensive care units (ICUs). A postal survey was sent to the 20 main ICUs in Israel. ⋯ Equipment and medications necessary for airway management are available in most of the units. Difficult airways in ICUs are mainly managed by anesthesiologists and ENT surgeons. Few ICUs have quality assurance meetings.

The reliability of manual reporting of clinical events in an anesthesia information management system (AIMS).
Manual incident reports significantly under-report adverse clinical events when compared with automated recordings of intraoperative data. Our goal was to determine the reliability of AIMS and CQI reports of adverse clinical events that had been witnessed and recorded by research assistants. ⋯ AIMS yielded a sensitivity of 38 % (95 % confidence interval [CI] 8.5-75.5 %), while the sensitivity of CQI reporting was 13 % (95 % CI 0.3-52.7 %). The low sensitivities of the AIMS and CQI reports suggest that user-reported AIMS and CQI data do not reliably include significant clinical events.

Validation of a measurement to predict upper airway collapsibility during sedation for colonoscopy.
Techniques to quantify the effects of sedation on upper airway collapsibility have been used as research tools in the laboratory and operating room. However, they have not been used previously in the usual clinical practice environment of colonoscopy sedation. The propensity for upper airway collapsibility, quantified as the critical pharyngeal pressure (P(crit)), was hypothesized to correlate with the need for clinical intervention to maintain ventilation. ⋯ The CIS was not predicted by the transformed baseline or sedated P(crit) with or without including demographics associated with sleep apnea syndrome. Although the NAP technique showed the expected changes with sedation in this clinical situation, we did not find that it predicted the need for clinical intervention during endoscopy. Our study was not large enough to test for subpopulations in which the test might be predictive; further studies of these particular groups are needed to determine the clinical utility of the NAP measurement.
