Tumor lysis syndrome is an oncologic emergency caused by rapid tumor cell breakdown and release of intracellular contents into the bloodstream. In this episode, we review the pathophysiology, risk factors, laboratory abnormalities, diagnostic criteria, prevention, and treatment of tumor lysis syndrome.

The oxygen-hemoglobin dissociation curve is a foundational concept for understanding oxygen binding, oxygen unloading, hypoxemia, and tissue oxygen delivery. In this episode, we review what the oxygen-hemoglobin dissociation curve represents, how hemoglobin saturation relates to PaO2, what P50 means, and how left and right shifts change hemoglobin’s affinity for oxygen.

Volume control and pressure control are two of the most important mechanical ventilation modes used in critical care. In this episode, we review the physiologic principles behind both modes, explain how ventilator settings influence pressure, flow, and tidal volume, interpret ventilator scalars and waveforms, and compare the advantages, limitations, and bedside applications of each mode.

Dead space ventilation is a foundational concept in pulmonary physiology and mechanical ventilation. In this episode, we review anatomic dead space, alveolar dead space, physiologic dead space, and how dead space relates to ventilation-perfusion mismatch, shunt physiology, CO2 clearance, respiratory failure, and bedside clinical interpretation.
