When signs of return of spontaneous circulation (ROSC) occur, where should you perform the pulse check?

When assessing for signs of return of spontaneous circulation (ROSC) following a cardiac arrest, it is essential to check the pulse in areas where the blood flow is most significant and accessible. The carotid and femoral arteries are the best choices for this purpose.

The carotid artery, located in the neck, is easily palpated and provides quick access to assess the central circulation in adults. Checking the carotid pulse is a standard practice since it gives immediate feedback on whether effective blood circulation has resumed.

The femoral artery, located in the groin, is another strong site for pulse assessment. It can be especially useful in situations where the patient may not be responsive, or when performing CPR on an individual with a larger body size, as it can be easier to locate.

Both of these arteries are major vessels that indicate adequate circulation, making them the appropriate sites for pulse checks when ROSC is suspected.

While other arteries, such as the radial and brachial, can be used to assess circulation, they are generally less reliable for confirming ROSC in adults due to their smaller size and the possibility of being less palpable in certain conditions.
