Which of the following is NOT a reversible cause during resuscitation?

In the context of advanced life support, recognizing reversible causes of cardiac arrest is crucial for effective resuscitation. Among the options listed, hyperglycemia is not typically classified as a reversible cause during resuscitation.

Reversible causes are conditions that can be quickly identified and treated in the resuscitation setting, allowing for the possibility of restoring normal cardiac function. Hypoxia and hypovolemia can be addressed immediately through actions such as ensuring adequate ventilation and fluid resuscitation, while tension pneumothorax can be relieved through procedures such as needle decompression or chest tube placement, both of which can rapidly improve hemodynamics and oxygenation.

Hyperglycemia, while it may require management in the context of overall patient care, is not an urgent cause that can be immediately reversed during the resuscitation process. It generally necessitates a more prolonged intervention, such as insulin administration, rather than an immediate life-saving measure. This distinguishes it from the other options, which can be swiftly acted upon to stabilize the patient during a critical emergency.
