Mechanical ventilation is a routine intervention for the critically ill but patients' experiences of this intervention are largely hidden from clinicians. A comprehensive understanding of Intensive Care Units survivors' accounts is required to provide health professionals with evidence about the patients' experience to deliver patient-centred care. ⋯ For the first time the pooling of qualitative findings from international studies, using meta-ethnography, has provided a patient-centred model of mechanical ventilation survivors' experiences of their care processes. Patients may actively engage or passively endure the treatment burden associated with mechanical ventilation.

Observational Study
Evaluation of three pain assessment scales used for ventilated neonates.
To compare and evaluate the reliability, validity, feasibility, clinical utility, and nurses' preference of the Premature Infant Pain Profile-Revised, the Neonatal Pain, Agitation, and Sedation Scale, and the Neonatal Infant Acute Pain Assessment Scale used for procedural pain in ventilated neonates. ⋯ Choosing a valid, reliable, feasible and practical measurement is the key step for better management of procedural pain for ventilated newborns. Using the right and suitable tool is helpful to accurately identify pain, ultimately improve the neonatal care and outcomes.

Multicenter Study Observational Study
Adoption of Lung Protective ventilation IN patients undergoing Emergency laparotomy: the ALPINE study. A prospective multicentre observational study.
Emergency abdominal surgery is associated with a high risk of postoperative pulmonary complications (PPCs). The primary aim of this study was to determine whether patients undergoing emergency laparotomy are ventilated using a lung-protective ventilation strategy employing tidal volume ≤8 ml kg-1 ideal body weight-1, PEEP >5 cm H2O, and recruitment manoeuvres. The secondary aim was to investigate the association between ventilation factors (lung-protective ventilation strategy, intraoperative FiO2, and peak inspiratory pressure) and the occurrence of PPCs. ⋯ Both intraoperative peak inspiratory pressure and FiO2 are independent factors significantly associated with development of a postoperative pulmonary complication in emergency laparotomy patients. Further studies are required to identify causality and to demonstrate if their manipulation could lead to better clinical outcomes.

Multicenter Study Observational StudySafety incidents in airway and mechanical ventilation in Spanish ICUs: The IVeMVA study.
To assess incidence, related factors and characteristics of safety incidents associated with the whole process of airway management and mechanical ventilation (MV) in Spanish ICUs. ⋯ MV is a risk process in critical patients. Although most incidents did not harm patients, some caused damage and a few were related to the patient's death or permanent damage. Preventability is high.

Low positive end-expiratory pressure (PEEP) can result in alveolar derecruitment, and high PEEP or high tidal volume (VT) in lung overdistension. We investigated cardiogenic oscillations (COS) in the airway pressure signal to investigate whether these oscillations can assess unfavourable intratidal events. COS induce short instantaneous compliance increases within the pressure-volume curve, and consequently in the compliance-volume curve. We hypothesised that increases in COS-induced compliance reflect non-linear intratidal respiratory system mechanics. ⋯ Heartbeat-induced oscillations within the course of the inspiratory pressure-volume curve reflect non-linear intratidal respiratory system mechanics. The analysis of these cardiogenic oscillations can be used to detect intratidal derecruitment and overdistension and, hence, to guide PEEP and VT settings that are optimal for respiratory system mechanics.
