A patient who sustained massive trauma has just lost consciousness. A cardiac monitor is initiated, and it reveals pulseless electrical activity
The team working on this patient would quickly assess for which conditions? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply. 1. Loose electrical leads to the monitor
2. Cardiac tamponade
3. Tension pneumothorax
4. Profound hypovolemia
5. Spinal cord injury
2,3,4
Rationale 1: The patient has a rhythm but no pulse. The monitor is working correctly.
Rationale 2: Cardiac tamponade would cause standstill of the heart so no pulse would be generated, but electrical activity would still be present for a period of time.
Rationale 3: Tension pneumothorax can result in mediastinal shift, which would reduce or stop the flow of blood from the heart. This can make pulses very weak or absent. Electrical activity would be present for a period of time.
Rationale 4: If hypovolemia is profound, there is little venous return to the heart, resulting in very diminished cardiac output. Pulses would be very weak or absent. Electrical activity would be present for a period of time.
Rationale 5: Spinal cord injury would result in paralysis and might affect cardiac status but would not be characterized by pulseless electrical activity.
