Critical-care and respiratory clinicians get an ARDS refresher covering alveolar-capillary leak, shunt, V/Q mismatch and reduced lung compliance. Practical management includes predicted-body-weight ventilation, plateau and driving-pressure review, early proning, dexamethasone, conservative fluid management, rescue therapies and palliative care alongside active treatment.

Critical-care, emergency and respiratory teams get a physiology-led airway strategy for refractory hypoxaemia, shock, severe metabolic acidosis and right ventricular failure. It links limited safe apnoea time with awake flexible endoscopic intubation, careful topicalisation, continued high-flow nasal oxygen and a prepared rescue plan.

Emergency and critical-care clinicians get a physiology-led approach to intubation in haemorrhagic shock, severe metabolic acidosis, hypoxaemic respiratory failure, pulmonary embolism and traumatic brain injury. It connects induction-related hypotension, apnoea, positive-pressure ventilation and right ventricular failure with preoxygenation, haemodynamic preparation, drug selection and team roles.

Critical-care, emergency and acute medicine clinicians get a detailed arterial-line update for shock, vasoactive titration, severe hypoxaemia, cardiac arrest and VA ECMO. It links decision-critical monitoring, ultrasound-guided insertion, site choice, securement, levelling, zeroing, damping checks and waveform interpretation to safer bedside decisions.

Critical-care clinicians get a wide physiology and evidence-appraisal mailbag. Fluid responsiveness, passive leg raise, ICU sleep, shunt physiology, lactate, DKA triggers, septic shock beta-blockade, airway difficulty and mechanical circulatory support are handled through bedside phenotype and measured response.

Critical-care, cardiology and emergency clinicians get a bedside approach to broad-complex tachycardia, VT storm and torsades. The useful distinctions are structural heart disease versus acquired long-QT triggers, with synchronised cardioversion, sedation, vasopressors, sympatholysis and device interrogation in view.

Allergy labels need phenotype, timing and severity before they reshape critical care choices. Alpha-gal syndrome, latex-fruit reactions, protamine hypersensitivity and iodine myths are used to separate true clinical risk from inherited labels that block useful treatment.

ICU sustainability is framed as high-value care, not rationing. Deprescribing, enteral conversion, correct waste segregation, fewer unnecessary investigations and safe reuse of patient-specific items can reduce carbon impact while removing low-value treatment.

APRV is a specialist listen for clinicians who manage severe ARDS. The point is not a new ventilator recipe: T low, waveform review, carbon dioxide trends and spontaneous effort all decide whether recruitment is helping or causing harm.

For clinicians around transplant or ECMO services, this gives the practical ICU questions that shape candidacy and graft survival. The distinctions around status seven, awake tracheostomy or ECMO bridging, primary graft dysfunction, and infection versus rejection are the main reasons to spend the time.
