Hs and Ts Resources

Hs and Ts are a mnemonic used in Advanced Cardiac Life Support (ACLS) to identify the most common reversible causes of cardiac arrest, making it a foundational concept taught in standard acls certifications. Each letter represents a potential underlying condition that, if recognized and treated promptly, can restore circulation and improve patient outcomes.

They are important because not all cardiac arrests are caused by irreversible heart damage. By systematically considering the Hs and Ts during resuscitation, providers can uncover and treat specific underlying problems. For instance, they can correct hypoxia by ensuring adequate ventilation with high amounts of oxygen, or address hypovolemia caused by severe blood loss. Providers must also evaluate for hydrogen ion accumulation, such as respiratory acidosis, which is often confirmed via an arterial blood gas and may prompt targeted treatments like sodium bicarbonate. Recognizing the “Ts” is equally vital, whether it means identifying toxins through ECG changes like a prolonged qt interval, or spotting a tension pneumothorax by noting unequal breath sounds and tracheal deviation. Ultimately, this structured approach is a critical part of ACLS and the broader chain of survival.
