Trace the path of fresh gas flow through a circle system and calculate the effect of fresh gas flow rate, absorber exhaustion, and circuit volume on rebreathing.

Explain vaporizer design (variable-bypass, measured-flow, desflurane heated unit), factors that alter output (flow, temperature, back pressure, altitude), and cause of agent-specific misfilling hazards.

Describe the physics of laminar versus turbulent flow, the Hagen-Poiseuille equation, and how resistance, compliance, and the Venturi effect govern flow meters, Venturi masks, and jet ventilation.

Explain the principles, limitations, and failure modes of pulse oximetry, including dyshemoglobinemias, low perfusion, and motion artifact.

Compare invasive and noninvasive blood pressure measurement, describing damping, resonance, zeroing, and leveling errors and how each distorts the waveform.

Describe neuromuscular monitoring modalities (train-of-four, post-tetanic count, double-burst, quantitative versus qualitative) and the criteria for safe extubation.

Summarize processed EEG and depth-of-anesthesia monitoring, including raw EEG features, burst suppression, and the limits of index values in specific drug states.

Apply pharmacokinetic principles (volume of distribution, clearance, half-time, context-sensitive half-time, compartment models) to compare propofol, thiopental, and fentanyl infusions.

Calculate and interpret MAC, MAC fractions and additive interactions among volatile agents, and explain factors that raise or lower MAC.

Explain the uptake and distribution of inhaled anesthetics: the concentration and second gas effects, ventilation and perfusion effects, and the influence of cardiac output.

Describe pharmacodynamic concepts of potency, efficacy, receptor affinity, tachyphylaxis, and tolerance as they apply to opioids and benzodiazepines.

Contrast first-order and zero-order elimination, and predict the effect of hepatic or renal impairment on drug duration.

Compare induction agents (propofol, etomidate, ketamine, barbiturates) on hemodynamics, emergence, and specific contraindications, and select one for three stated patient scenarios.

Classify neuromuscular blocking agents, explain depolarizing versus nondepolarizing mechanisms, metabolism, and reversal with anticholinesterases and sugammadex.

Distinguish amide and ester local anesthetics, compute maximum allowable doses with and without epinephrine, and recognize local anesthetic systemic toxicity and its treatment.

Outline opioid classes, equianalgesic conversions, and the mechanism and management of opioid-induced respiratory depression and hyperalgesia.

Explain the pharmacology of vasopressors and inotropes used in the operating room, including receptor activity and dose ranges.

Explain oxygen delivery and consumption, the oxyhemoglobin dissociation curve, and how pH, temperature, and 2,3-DPG shift it.

Describe the physiology of ventilation-perfusion matching, shunt, dead space, and hypoxic pulmonary vasoconstriction, and apply them to one-lung ventilation.

Explain intrathoracic pressure effects on venous return, the determinants of cardiac output, and the Frank-Starling relationship.

Interpret the pulmonary artery catheter and thermodilution-derived values, and calculate systemic and pulmonary vascular resistance from a given hemodynamic profile.

Predict how positive pressure ventilation, pneumoperitoneum, and steep positioning alter hemodynamics and respiratory mechanics.

Describe renal blood flow autoregulation, glomerular filtration, and how anesthesia and hypovolemia change urine output and creatinine clearance.

Explain hepatic blood flow, the first-pass effect, and how cirrhosis alters drug metabolism and coagulation.

Summarize cerebral blood flow autoregulation, the Monro-Kellie doctrine, and the effects of PaCO2, PaO2, and anesthetics on intracranial pressure.

Outline endocrine and metabolic responses to surgery, including the cortisol, catecholamine, and glucose responses, and the implications for diabetic patients.

Explain thermoregulation, the mechanisms of perioperative hypothermia, and the physiology behind malignant hyperthermia susceptibility.

Formulate a stepwise plan for predicted difficult airway management, including preoxygenation, device selection, and failed airway escalation.

Construct an anesthetic plan for three common procedures (laparoscopic cholecystectomy, total hip arthroplasty, cesarean delivery) covering induction, maintenance, monitoring, and analgesia.

Describe the recognition and immediate management of intraoperative crises: anaphylaxis, malignant hyperthermia, bronchospasm, and massive hemorrhage.

Explain positioning physiology and injury prevention for supine, prone, lateral, and sitting positions.

Compare neuraxial and peripheral regional techniques on indications, block level, and major complications.

Integrate pharmacology and clinical management by justifying drug selection for ten high-yield clinical vignettes.

Review personal error log from weeks 1-7 and restate each missed concept in your own words.

Complete timed practice under exam conditions to build pacing and stamina.

Identify the three weakest subtopics and write a targeted 30-day maintenance plan.
