What are the Hs and Ts of ACLS?

The most common underlying causes of cardiac arrest are presented as H’s and T’s. The H’s stand for hypovolemia, hypoxia, hydrogen ion or acidosis, hypokalemia, hyperkalemia, and hypothermia. The T’s are tension pneumothorax, cardiac tamponade, toxins, pulmonary thrombosis, and coronary thrombosis.Click to see full answer. Herein, what are the 5 H’s and T’s? These conditions are often referred to by the mnemonic “H’s and T’s”: Hypoxia: Cardiac arrest caused by pure hypoxemia is uncommon. Hypovelemia: Hypothermia: Hyperkalemia/Hypokalemia: Hydrogen Ion (Acidosis): Tension Pneumothorax: Tamponade (Cardiac): Toxins: One may also ask, what can cause pulseless electrical activity? PEA is always caused by a profound cardiovascular insult (eg, severe prolonged hypoxia or acidosis or extreme hypovolemia or flow-restricting pulmonary embolus). The initial insult weakens cardiac contraction, and this situation is exacerbated by worsening acidosis, hypoxia, and increasing vagal tone. Similarly, what are 4 H’s and 4 T’s? However, in practice while performing CPR often in stressful situations, it is difficult to remember all 4 “Ts” and 4 “Hs” causes (hypoxia, hypokalaemia/hyperkalaemia, hypothermia/hyperthermia, hypovolaemia, tension pneumothorax, tamponade, thrombosis, toxins), especially for medical students, young doctors and doctorsWhat are the ACLS drugs?
