ABSTRACT
BACKGROUND: Lean Six Sigma processes are used in health care systems to increase safety and efficiency. Daily huddles, one tool of the Lean Six Sigma process, have been used to increase patient safety, facilitate efficiency in problem solving, promote optimal patient outcomes, and reduce poor communication. Huddle utilization by respiratory care departments has not been previously reported. We describe our process of implementing daily huddles and the impact on departmental problem solving. METHOD: A descriptive study of a quality improvement intervention and a retrospective study of prospectively collected data were performed. The respiratory care department was trained in the utilization of a daily huddle process to resolve issues and identify process improvement opportunities. Huddles were performed at the beginning of each shift. Process improvement opportunities were raised by the respiratory therapy staff using the following categories: Safety/Service, Methods, Equipment, Supplies, and Associates. Opportunities were placed within 3 categories; quick hits (resolution in 1-3 d), complex problems (resolution in 3-7 d), and projects (resolution in > 7 d). All opportunities included a problem statement, an immediate countermeasure, a problem leader, and a due date. Items requiring interdisciplinary support were escalated to the organizational patient care services huddle. We evaluated the number and nature of process improvement opportunities raised in huddles from January 1 through December 31, 2018, to better understand the impact of daily huddles. RESULTS: A total of 366 process improvement opportunities were raised during huddles. Of those, 245 (67%) were quick hits, 77 (21%) were complex, and 44 (12%) were projects. Resolution of 174 (47.5%) opportunities was completed using only the resources of the respiratory care department, and 157 (43%) were resolved with additional interdisciplinary involvement. A small portion 35 (9.5%) of opportunities required escalation to the organizational multidisciplinary huddle for resolution. All process improvement opportunities were resolved at the end of the study period (mean ± SD of 30.5 ± 7.7 per month). CONCLUSIONS: Twice-daily huddles implemented by our respiratory care department allowed for identification and timely resolution of process improvement opportunities.

Inhaled nitric oxide (iNO) may be continued during the transition from invasive to noninvasive respiratory support. Upper airway obstruction from laryngeal edema following extubation and lower airway obstruction from asthma and bronchiolitis may be managed with inhaled helium. The coadministration of helium with iNO and the impact on delivered amounts of iNO have not been extensively studied. A bench model simulating a spontaneously breathing infant received iNO at varying preset doses delivered with either helium-oxygen or nitrogen-oxygen via a Vapotherm unit. iNO levels were measured at the simulated trachea. Results from the two conditions were compared using t-tests. When nitrogen-oxygen was used, there was no difference between preset and measured iNO levels. A significant difference was present when helium-oxygen was used, with a 10-fold increase in measured iNO levels compared with preset values. The use of helium resulted in a significant increase in measured iNO at the level of the simulated trachea. Clinicians must be aware that iNO will not be delivered at prescribed doses when used with helium under the conditions used in this study.
ABSTRACT
INTRODUCTION: High-flow nasal cannula therapy (HFNC) has been shown to be more effective than continuous positive airway pressure (CPAP) in reducing intubations and ventilator days. HFNC likely provides mechanisms to support respiratory efficiency beyond application of distending pressure. We reason that HFNC washout of nasopharyngeal dead space impacts CO(2) removal along with oxygenation. The aim of this study was to demonstrate the flow dependence of CO(2) reduction and improved oxygenation during HFNC and the dependence on leak around the nasal prongs. MATERIALS AND METHODS: Neonatal piglets (n=13; 2-6 kg) were injured with IV oleic acid and supported with HFNC at 2 through 8 L/min. High and low leak around the nasal prongs was accomplished by using single and double prong cannulae, respectively. Measurement of hemodynamic, respiratory and blood gas parameters were made at each setting following 10 min for physiologic equilibration. Tracheal pressures were recorded by transmural catheters. RESULTS: With HFNC, CO(2) trended downward in a flow-dependent manner independent of leak. Oxygenation and tracheal pressures increased in a flow-dependent manner with the greatest effect during double prong. At 8 L/min, tracheal pressures did not exceed 6 ± 1 cmH(2) O. CONCLUSIONS: HFNC improves gas exchange in a flow-dependent manner; double prong had greater impact on O(2;) single prong had greater impact on CO(2) elimination.
