How to perform Point of Care Ultrasound at resuscitation and when it is useful.

Point of Care Ultrasound (POCUS) can be useful as a tool before, during and after the performance of cardiopulmonary resuscitation (CPR). Before or after resuscitation it can help with monitoring unstable hemodynamics, has the potential to identify reversible causes if patient deteriorates. During resuscitation POCUS can help detect potentially treatable causes of the cardiac arrest. Performance of POCUS while resuscitation requires experienced sonologists and a good team structure to embed the examination in advanced cardiovascular life support (ACLS) algorithms. This article gives an overview and tips about how to detect potential reversible causes of patient deterioration in all three phases of CPR. We describe some special situations in which resuscitation could take place. Further we give a comment about sonographic education of physicians and nonacademic medical staf.
