End-tidal carbon dioxide (EtCO2) monitoring is widely used as a surrogate for the partial pressure of carbon dioxide (PCO2) in critically ill patients receiving manual or mechanical ventilation in prehospital, emergency, and critical care settings. Specific targets for ETCO2 are a key component of Emergency Medical Services (EMS) protocols, especially for specific patient groups such as those with traumatic brain injury. However, the correlation between EtCO2 and venous or arterial PCO2 is uncertain. We aimed to assess the correlation between EtCO2 and PCO2 in intubated patients undergoing critical care transport (CCT), and in specific subgroups of patients. ⋯ We identified substantial differences between EtCO2 and PCO2 across patients with medical and traumatic conditions undergoing critical care transport. The PCO2 assessment should be strongly considered as part of ventilatory management in patients encountered in emergency and critical care settings.

Review Meta Analysis
Efficacy of Continuous Lateral Rotation Therapy in Mechanically Ventilated Critically Ill Adults on Clinical Outcomes.
This Population, Intervention, Comparison, and Outcomes-guided systematic review assesses continuous lateral rotation therapy versus conventional position changes in mechanically ventilated critically ill adults, evaluating mortality, ICU length of stay (LOS), and hospital LOS as primary outcomes and respiratory function, mechanical ventilation duration, pulmonary complications, and adverse events as secondary outcomes. ⋯ Continuous lateral rotation therapy showed no significant difference in primary outcomes (mortality, ICU and hospital LOS) but revealed significant differences in secondary outcomes (consistently reduced nosocomial pneumonia, with a minor effect on mechanical ventilation duration), supported by moderate certainty. Very low certainty for other outcomes highlights the need for current studies in diverse clinical settings and protocols to assess continuous lateral rotation therapy effectiveness.

Adaptive pressure control-continuous mandatory ventilation (APC-CMV) is a frequently utilized ventilator mode in ICU settings. This analysis compared APC-CMV and traditional volume control-continuous mandatory ventilation (VC-CMV) mode, describing factors associated with initiation, maintenance, and changes in settings of each mode. ⋯ APC-CMV was highly utilized in the medical ICU. Subjects on APC-CMV had more ventilator setting changes/d than those on VC-CMV. APC-CMV offered no advantage of reduced setting adjustments or less sedation compared to VC-CMV.

Numerous studies have demonstrated that hospice palliative care interventions for cancer patients can reduce health care utilzation. In Taiwan, 20-25% of patients who require mechanical ventilation are using prolonged mechanical ventilation (PMV); however, only a limited number of studies have addressed the effectiveness of hospice palliative care for these patients. This study investigated the impact of hospice palliative care utilization on medical utilization among subjects using PMV. ⋯ Subjects undergoing PMV while receiving hospice palliative care experienced significant reductions in total hospitalization costs, ICU admissions, cardiopulmonary resuscitation, and medical expenses within 14 d before death.
