Final answer:

Waveform capnography is used to ensure correct ETT placement and can also monitor CPR quality by giving real-time feedback on the effectiveness of chest compressions. It complements the use of ECG, which helps in diagnosing cardiac conditions but requires expert interpretation.

Step-by-step explanation:

Waveform capnography is a tool that is primarily used to monitor endotracheal tube (ETT) placement by measuring the amount of carbon dioxide in the breaths of intubated patients. However, it can also be a valuable asset in monitoring cardiopulmonary resuscitation (CPR) quality. During CPR, adequate chest compressions are essential for maintaining blood flow to the heart and brain. The partial pressure of end-tidal CO2 (PetCO₂) measured by capnography can reflect the effectiveness of chest compressions, as better compressions lead to better pulmonary blood flow and higher CO₂ readings. Hence, capnography provides immediate, non-invasive feedback on the effectiveness of CPR, allowing for adjustments in real-time to ensure high-quality resuscitations.

Electrocardiography (ECG) is another technique used to analyze the heart's electrical activity, providing insights into the heart's condition, including detecting myocardial infarctions (MI) and other cardiac abnormalities. ECG interpretations require a well-trained eye, as they are complex and can vary between individuals. Advances in ECG technology have made portable ECG monitors widely available, contributing to rapid diagnostics in various environments, including emergency vehicles and at-home care.
