If capnography shows a reading of less than 10 mmHg during CPR, what immediate action should be taken?

A capnography reading of less than 10 mmHg during CPR is indicative of poor cardiac output and inadequate ventilation, often pointing to the need for reassessment of the quality of chest compressions. Changing the compressor is crucial in this scenario because high-quality chest compressions are essential to improve blood flow and, consequently, the effectiveness of CPR.

When compressions are performed effectively and without interruption, it significantly increases the likelihood of returning spontaneous circulation. If a parity of compressions is not maintained, or if the person performing compressions is losing efficacy due to fatigue, switching to a different compressor can help maintain the quality and depth of compressions necessary for effective resuscitation.

The other options are not immediate priorities in response to the capnography reading. Although adjustments to drug administration or ventilation may be necessary later, ensuring high-quality CPR through adequate and effective compressions remains the priority in such a situation.
