Diagnosis and management of hyponatremia in the ICU. Two questions drive everything: how sick is the brain right now, and how fast is the sodium allowed to rise. Treat severe symptoms immediately with hypertonic saline, classify by the four-question workup, then correct slowly — guarding against osmotic demyelination at every step.

Analgesia-first, light-sedation-by-default management of the intubated ICU patient. Treat pain before reaching for a sedative, target the lightest safe RASS, screen for delirium, and lift sedation daily. Use BIS to confirm depth when RASS can't be assessed.

Management of ARDS in adults. The mortality benefit comes from a small number of proven interventions — lung-protective ventilation, prone positioning, conservative fluids, and ECMO for the most refractory. Confirm the diagnosis (Global 2023 / Berlin), stratify severity, and follow the A→C ladder.

A coordinated daily approach to liberate ICU patients from pain, oversedation, delirium, and immobility. The elements reinforce each other — pain control enables lighter sedation, lighter sedation enables awakening and breathing trials, which enable mobility and engagement. Perform every element, every patient, every day.

Standard prevention bundles for every ICU patient. The discipline is the same across all nine: assess the indication daily, apply the bundle, and de-escalate the moment the indication ends. Run the Daily Prevention Checklist on rounds.

Post–ROSC neuroprotection for the comatose survivor of cardiac arrest. Pick a target and hold it, suppress shivering aggressively, protect MAP and oxygenation, then rewarm slowly and prevent fever to 72 h. Defer all neurologic prognostication. Adapt every target to your institutional protocol and the individual patient.

Determination of death by neurologic criteria (BD/DNC). A diagnosis with profound consequences — work the sequence in order: confirm prerequisites and clear all confounders before the exam, perform the clinical exam and apnea test, and use ancillary testing only when the exam or apnea test cannot be completed.

Trauma-bay-to-ICU management of moderate–severe TBI. Stop the secondary injury — avoid hypoxia and hypotension from the first minute, keep CO₂ and perfusion in range, and escalate ICP therapy in steps. Grade by post-resuscitation GCS, image early, and get neurosurgery in fast.

ED-to-ICU management of spontaneous intracerebral hemorrhage. Move fast on the first hour — secure the airway, lower the pressure, reverse the coagulopathy, and call neurosurgery — then characterize the clot, watch for expansion, and control ICP.

ICU management of intracranial hypertension and herniation. Work the ladder in order — optimize universal neuroprotection (Tier 0) before escalating, treat sustained ICP > 22 mmHg, and protect cerebral perfusion at every step. Reserve hyperventilation and barbiturates for rescue.

ED-to-ICU management of aneurysmal SAH. Two clocks run at once — prevent re-rupture before the aneurysm is secured (< 24 h), then watch days 7–10 for delayed cerebral ischemia. Control the pressure, reverse coagulopathy, start nimodipine, and admit to a high-volume center.

An oncologic emergency. Draw blood cultures from every lumen and a peripheral site, then give the first broad-spectrum antibiotic within 60 minutes — never wait on the workup. Layer MRSA and double Gram-negative coverage onto an antipseudomonal backbone by risk, support the failing circulation, and engage ID and Heme/Onc early.
