Nancy the neuron has just fired an action potential. Now she cannot fire another action potential until she resets her electrical potential. She is in a refractory period. The refractory period starts after the hyper-polarization of the neuron. In this phase the neurons is inhibited of generating further action potentials, and the recovery to resting potential of the neuron membrane begins with the potassium ions slowly leaking into the cell.
Given what we know, we can confirm that the primary method of confirming endotracheal tube placement within the trachea is a chest x-ray.
<h3>Why use an X-ray?</h3>
A chest x-ray of the patient will be the most secure way of confirming the placement of an endotracheal tube within the trachea given that it allows the professionals in question to see its exact placement. This ensures that the placement is correct and that the patient will not have respiratory issues.
Therefore, we can confirm that the primary method most often used for confirming endotracheal tube placement within the trachea is a chest x-ray.
