Three hours after disconnecting a patient from the ventilator, the patient shows bradycardia and hypotension; what is the next step in addition to chest compressions?

Three hours after disconnecting a patient from the ventilator, the patient shows bradycardia and hypotension; what is the next step in addition to chest compressions?

• A. Atropine
• B. Epinephrine
• C. External pacing
• D. Recheck endotracheal tube position

Answer: (D)

When a patient who is in CPR has bradycardia and hypotension, the first priority is to ensure effective ventilation by confirming the airway. A recent disconnect from a ventilator raises the possibility that the endotracheal tube has shifted, become disconnected, or is otherwise not delivering air to the lungs. If the airway isn’t delivering ventilation, oxygen delivery to the heart and brain is compromised, making chest compressions less effective and perpetuating the arrest rhythm. Rechecking the endotracheal tube position is essential. Verify that the tube is in the trachea (not esophagus) and that it remains at the appropriate depth. Use reliable signs: bilateral breath sounds, symmetrical chest rise, absence of gastric insufflation, and waveform capnography. If placement is incorrect, promptly reposition and re-secure the tube, provide adequate ventilation with 100% oxygen, and then continue resuscitation efforts. If the airway is confirmed and functioning, you would then proceed with other ACLS measures for bradycardia, such as pharmacologic support or pacing if indicated.
