Observational Study
Effect of mattress and bed frame deflection on real chest compression depth measured with two CPR sensors.
Implementation of chest compression (CC) feedback devices with a single force and deflection sensor (FDS) may improve the quality of CPR. However, CC depth may be overestimated if the patient is on a compliant surface. We have measured the true CC depth during in-hospital CPR using two FDSs on different bed and mattress types. ⋯ The use of FDS without real-time correction for deflection may result in CC depth not reaching the recommended depth of 50 mm.

Evaluate the roles of water temperature and submersion duration in the outcome of drowning victims. ⋯ A protective effect of cold water for drowning victims was not found; estimated submersion duration was the most powerful predictor of outcome. Recommendations for initiation of rescue and resuscitation efforts should be revised to reflect the very low likelihood of good outcome following submersion greater than 10 min.

Observational Study
Prevalence and risk factors for post-traumatic stress disorder in relatives of out-of-hospital cardiac arrest patients.
Prognostic uncertainty and surrogate decision-making demands associated with prolonged unconsciousness in out-of hospital cardiac arrest (OHCA) patients in the intensive care unit (ICU) may increase post-traumatic stress disorder (PTSD) risk in their relatives. Our aim was to study PTSD frequency and risk factors in relatives of OHCA patients. ⋯ Relatives of OHCA patients treated in the ICU are at increased risk of PTSD, which can be predicted based on six factors, three ICU-related and potentially at least partly modifiable. Further research is needed to validate our findings and to develop strategies to prevent PTSD in OHCA patients' relatives.
