Barriers to Patient Positioning for Telephone Cardiopulmonary Resuscitation in Out-Of-Hospital Cardiac Arrest.
9-1-1 callers often face barriers preventing them from starting Telephone CPR (TCPR). The most common problem is getting patients to a hard, flat surface. This study describes barriers callers report when trying to move patients to a hard, flat surface and assesses conditions associated with overcoming these barriers. ⋯ Inability to move patients to a hard, flat surface is associated with a reduced rate of TCPR and increased time to first compression. Assessing the conditions under which such barriers are overcome is important for telecommunicator training and can help improve rates and timeliness of TCPR.

Little is known about the most recent nationwide and regional trends in out-of-hospital cardiac arrest (OHCA) outcome. We therefore sought to investigate the recent nationwide and regional trends in OHCA outcome in Japan. ⋯ We found nationwide and regional improvement of favourable neurological outcomes from OHCA of medical origin with persistent regional variation.

Waveform capnography is considered the gold standard for verification of proper endotracheal tube placement, but current guidelines caution that it is unreliable in low-perfusion states such as cardiac arrest. Recent case reports found that long-deceased cadavers can produce capnographic waveforms. The purpose of this study was to determine the predictive value of waveform capnography for endotracheal tube placement verification and detection of misplacement using a cadaveric experimental model. ⋯ Though current guidelines question the reliability of waveform capnography for verifying endotracheal tube location during low-perfusion states such as cardiac arrest, our findings suggest that it is highly sensitive and specific.
