A,Normal Capnograph. I, Dead Space Expiration; II, Mixed Dead Space and Alveolar Gas Expiration; III, Alveolar Gas Expiration and Plateau; 0, Inspiration. Phase IV is an Upswing that Occurs at the End of Phase III.B,Capnographs that May Be Seen in Practice. 1, Rapidly Extinguishing Uncharacteristic Waveform, Compatible with Esophageal Intubation; 2, Regular Dips in End-Expiratory Plateau, Seen in Underventilated Lungs or in Patients Recovering from Neuromuscular Blockade; 3, Upward Shift in Baseline and Plateau, Seen with Rebreathing of Carbon Dioxide, Miscalibration, and So Forth; 4, Restrictive Pulmonary Disease; 5, Obstructive Pulmonary Disease; 6, Cardiogenic Oscillations

A,Electromyographic Response to Repeated Train-of-Four (Tof) Stimulation after Injection of a Nondepolarizing Agent. Each Vertical Bar is Composed of Four Individual Twitch Responses. Fade of Tof Response Eventually Leaves Only One Twitch (Approximately 90% Blockade).B,Reversal of the Blockade by Neostigmine and Atropine Given 45 Minutes Later Shows a Progressive Recovery of the Tof Response and Reduction in Fade with a Tof Ratio of 0.9

Age-Varying Spectral Changes in the Frontal Spectrogram During Infancy to Childhood, Showing the Absence of Alpha Oscillation Power from 0 to 3 Months of Age, with a Gradual Increase in Alpha Oscillation Power Thereafter, Becoming More Prominent and Sustained at Approximately 6 Months of Age
Age-Varying Spectral Changes in the Frontal Spectrogram in Children and Young Adults from 1 to 28 Years of Age, Highlighting that, Although the Eeg Structure is Qualitatively Preserved, the Power of the Oscillations Changes As a Function of Age
