Final answer:
An endotracheal tube is a tube used during CPR to maintain an open airway and assist with artificial ventilation. Compressions should not be stopped to fit the tube, and one breath is typically given every 6-8 seconds when using an endotracheal tube.
Step-by-step explanation:
An endotracheal tube is a tube that is inserted into a person's trachea during cardiopulmonary resuscitation (CPR) to help maintain an open airway and assist with artificial ventilation. It is typically used when a person is unable to breathe on their own.
During CPR, compressions should not be stopped to fit an endotracheal tube. Instead, the tube is inserted while compressions are ongoing. This is done by a healthcare professional who has been trained to perform the procedure.
When using an advanced airway like an endotracheal tube, the usual protocol is to give one breath every 6-8 seconds, which equates to 8-10 breaths per minute.
