Methods: A retrospective, observational study compared a group of 196 of general ICU patients managed exclusively on automated mechanical ventilation, adaptive support ventilation (ASV), to another group of 684 managed by usual, non-automated mechanical ventilation (No ASV). The data was collected in a unique access database designed to collect data for assessment of mechanical ventilation outcomes in a small medical center ICU. Results: The length of ventilator stay was non-significant between both groups, (81.7 ± 35.2 hours) in the ASV group; vs. (94.1 ± 35.1 hours) in the No ASV. Percent mortality was significantly less in the ASV group, 8.6% compared to 27.3% in the No ASV. Conclusion: Automated ventilation appears to be a safe ventilator strategy; however, cause effect relationships cannot be determined without further, more sophisticated studies.

Beneficial or not?","authors":"Denise Wheatley, Krystal Young","doi":"10.53097/jmv.10026","DOIUrl":"https://doi.org/10.53097/jmv.10026","url":null,"abstract":"Ventilators functions and features have evolved with the advancement of technology along with the addition of microprocessors. It is important to understand and examine the benefits and risks associated with these advanced automated modes. Adaptive Support Ventilation (ASV) is a mode that is unique to the Hamilton Medical ventilators, thereby limiting the number of clinicians who have experience with using this mode. ASV can make changes to respiratory rate and tidal volume and adjusting the driving pressure in the absence of a professional. ASV changes ventilator strategies when it detects changes to a patient’s lung dynamics. The scope of ASV mode is not universally understood. Respiratory therapists may feel their position would be threatened with the use of smart automated modes. This paper will aim to review the literature on the ASV mode of ventilation. The literature review will address the following research questions to broaden the understanding of the risks and benefits of the ASV mode. 1) Is the ASV mode effective for weaning patients? 2) Is ASV a safe mode of ventilation for patients with COPD and ARDS? 3) Is ASV a safe mode of ventilation with changes in lung dynamics? 4) Does ASV impact the bedside respiratory therapist? Conclusions: ASV appears to be at least effective or even more superior to other modes especially during weaning off mechanical ventilation, and in other forms of respiratory failure. More studies in different clinical conditions and head-to-head with other modes.

It is estimated that the prevalence of GI complications in those patients is approximately 50-80% and lots of those go undiagnosed. Complications can affect different parts of the GI system, including the esophagus, stomach, small intestine, large intestine, liver, and pancreas. Effects might include dysmotility, diarrhea, inflammation, infection, direct mucosal injuries, ulcerations, and bleeding, and it can be associated with high mortality rates. Moreover, it is believed that the GI tract has a significant contribution in the development of multiple organ dysfunction syndrome (MODS) in critically ill patients. Mechanical ventilation either alone or in association with other critical illness may have a multitude of effects on almost all the organs of the gastro-intestinal tract. Attention of those interaction and side effects can improve outcomes and potentially mortality.

Unfortunately, its clinical value continues to be debatable. One of the many reasons responsible is the lack of consistency between its settings in clinical practice and research. We hypothesized that clinicians disagree on specific methods when establishing these parameters. Materials and Methods: A questionnaire-based survey was developed and sent to clinicians (critical care attending physician, critical care fellows in training and respiratory therapists) in about one hundred different academic hospitals with critical care training program. The survey consisted of ten questions including each of the four major APRV settings: T-High, T-Low, P-High, and P-Low. The survey was anonymous. Main results: Amongst the 187 respondents, there were significant disagreements between different categories of clinicians regarding methodology for establishing initial settings of APRV. However, when the responses were analyzed after sub-grouping based on categories of clinicians (Critical care attending physician vs critical care fellows vs respiratory therapists), no significant differences could be found. Conclusions: There is no agreement between different categories of clinicians when it comes to the methodology for establishing initial APRV settings. Our study highlights the need for larger clinical trials comparing different approaches to the same which could then be used for establishing scientific guidelines based on best evidence.

However, it is unknown which method of such a calculation gives the more accurate results. Design: We collected data using three different methods of calculating ventilator length of stay in a community hospital ICU. The first method is the walk-through method for collection of data at 6 am, the second is a data base collection system we created where data was collected by respiratory therapists in a daily ventilator patient log then entered into the database, and finally from query of medical charges for ventilator days from financial department Results: There was statistically significant disagreement between the three methods. The walk though method and data base were not statistically different, but the data from financial charges overestimated the ventilator length of stay. Additionally, there was not statistically significant differences between the time of the walk-through data collection. Conclusion: Ventilator days and hours should be measured by a precise database rather than indirect methods of estimation like walk-through or financial charges. Patient exposure to risk, and reporting of ventilator time, whether days or hours should be measured directly, not estimated. A larger study needs to be performed to examine this variation in a broader medical setting.
