Letter: During Cardiopulmonary Resuscitation in an Arrested Hypothermic Patient with a Potentially Stiff Chest, Carotid Ultrasound May Confirm Orthograde Blood Flow.

In conclusion, in hypothermic CA patients with a potentially stiff chest, using POCUS, orthograde blood flow in the common carotid arteries in synchrony with chest compressions can be quickly and reliably assessed. The blood flow is indicative of the effectiveness of chest compressions and can help in the decision-making regarding continuation or termination of CPR in case of a patient with a potentially stiff chest.
