“…The nursing staff need to turn the ventilated patients every few hours to lessen the risk of inducing ventilator-associated pneumonia and other related problems. [22] Usually, at least two nurses must carry out the turning of one patient. It is unrealistic to request the nurses to maintain total silence through the process.…”

The patients in the Intensive Care Units are often exposed to excessive levels of noise and activities. They can suffer from sleep disturbance, especially at night, but they are often too ill to cope with the poor environment. This article investigates the acoustic environment of typical intensive care wards in the UK, based on long period nocturnal measurements, and examines the differences between singlebed and multibed wards, using statistical analysis. It has been shown that the acoustic environment differs significantly every night. There are also significant differences between the noise levels in the singlebed and multibed wards, where acoustic ceilings are present. Despite the similar background noises in both ward types, more intrusive noises tend to originate from the multibed wards, while more extreme sounds are likely to occur in the single wards. The sound levels in the measured wards for each night are in excess of the World Health Organization's (WHO) guide levels by at least 20 dBA, dominantly at the middle frequencies. Although the sound level at night varies less than that in the daytime, the nocturnal acoustic environment is not dependant on any specific time, thus neither the noisiest nor quietest period can be determined. It is expected that the statistical analysis of the collected data will provide essential information for the development of relevant guidelines and noise reduction strategies.

Abstract-The automation of tasks in an intensive care unit can be beneficial for the patient's recovery and also can reduce the workload of the physicians. That is why research is looking for different tasks, which can be performed by automated machines. One specific project, our group is working on, is the automation of blood pressure regulation with drugs for patients task of the physicians, knowledge has to be gathered about, how the physicians decide on according treatment actions. As this is an everyday task, the easiest way to analyze and understand the treatment decisions is to look at taken decisions in actual patients. For this purpose a system has been set up, which can be connected to both the patient monitor and the syringe pumps, which infuse the different drugs. There were different requirements from the technical, medical point of view and also from an ethic committee, which had to be taken into account. Given those requirements hardware was chosen and suitable software was implemented. First tests showed, that the system can be operated in the intensive care unit and provide data for further research.

Purpose To estimate effect sizes for a trial to compare preventable pulmonary complications (PPCs), turning-related adverse events, mechanical ventilation duration, intensive care unit (ICU) length of stay, and ICU mortality between patients randomized to 2-hourly manual or continuous automated lateral rotation. Methods Randomized controlled trial pilot study with 15 patients selected randomly from eligible medical-surgical ICU patients from 2 tertiary hospitals and assigned randomly to the manualturn or automated-turn protocol for up to 7 consecutive days. A radiologist blinded to group and site assessed serial chest radiographs for PPCs. Repeated-measures analysis with linear mixed models was used to estimate change in PPC score, and Wilcoxon rank sum or Fisher exact test was used to compare group differences in the secondary outcomes. Results Of 16 patients enrolled, 12 (75%) completed the study. Data from 15 patients, 7 manual turn and 8 automated turn, were analyzed. Between-group differences in PPC incidence (67% overall), change in PPC score (β = 0.15, manual turn and β = -0.44, automated turn), and secondary outcomes were not significant (P > .05). Standardized effect sizes were small to moderate for the outcome variables. A sample size of 54 patients would be needed to detect statistically significant between-group differences in PPC over time. Conclusions The incidence of PPCs in adult patients receiving mechanical ventilation in a medical-surgical ICU was high. Automated turning decreased PPCs with time but had little effect on secondary outcomes. Safety outcomes were not substantially different between groups. A modest efficacy effect supported reduced PPCs with automated turning to the lateral position.
