<ul>
        <li>
                Resuscitation of the patient in cardiac arrest can be stressful, chaotic, and variable depending on the setting.</li>
        <li>
                Capnography is a valuable tool in the management of patients in cardiac arrest.</li>
        <li>
                Heradstveit, et al. published a pneumonic for the use of capnography during cardiac arrest:
                <ul>
                        <li>
                                <strong>P</strong> - Position of the tube
                                <ul>
                                        <li>
                                                The sensivity and specificity of capnography for endotracheal tube confirmation is superior to auscultation and capnometry.</li>
                                </ul>
                        </li>
                        <li>
                                <strong>Q</strong> - Quality of CPR
                                <ul>
                                        <li>
                                                Early detection of poor-quality compressions.</li>
                                </ul>
                        </li>
                        <li>
                                <strong>R</strong> - ROSC
                                <ul>
                                        <li>
                                                A sudden increase in end-tidal CO2 can indicate ROSC without interrupting CPR for pulse checks.</li>
                                </ul>
                        </li>
                        <li>
                                <strong>S</strong> - Strategy
                                <ul>
                                        <li>
                                                May assist clinicians in determining underlying etiology of cardiac arrest.</li>
                                </ul>
                        </li>
                        <li>
                                <strong>T</strong> - Termination
                                <ul>
                                        <li>
                                                An end-tidal CO2 value < 10 mm Hg after 20 min of resuscitation has been shown to be very accurate in predicting death.</li>
                                </ul>
