Ventilator pressures and bronchiolitis bedside assessment are the focus of the clinical learning, with stroke trial appraisal and pre-hospital culture adding system context.
After trauma intubation, peak pressure, plateau pressure and expired tidal volume are diagnostic data, not just ventilator numbers.
Today’s clinical briefing centres on two common acute-care problems: ventilation after major trauma and bronchiolitis in infants. The trauma ventilation episode turns the ventilator into a diagnostic tool immediately after intubation. Peak pressure, plateau pressure, expired tidal volume and waveforms help separate poor compliance, airway resistance, pneumothorax, pulmonary contusion, aspiration, abdominal pressure and major air leak. It also keeps oxygenation decisions tied to haemorrhage, acidaemia, traumatic brain injury, chest tube function and selective VV ECMO discussion.
Bronchiolitis adds the paediatric bedside thread. A typical infant with cough, congestion, tachypnoea, wheeze or coarse crackles is usually diagnosed clinically, with escalation guided by work of breathing, fatigue, perfusion, feeding, wet nappies and trajectory rather than a single oxygen saturation. The episode also reinforces restraint around routine investigations and medications that may create false positives or add distress without improving meaningful outcomes.
The stroke prevention item is a concise trial-appraisal update: asundexian targets factor XIa and was studied after recent non-cardioembolic ischaemic stroke or high-risk TIA, not atrial fibrillation. The pre-hospital leadership episode shifts from physiology to systems, focusing on psychological safety, inclusive discussion, feedback, delegation and marginal gains in trauma care.
Acute-care, critical-care and trauma teams get a practical post-intubation ventilation framework. Peak pressure, plateau pressure, delivered tidal volume, waveform shape, air leak, pneumothorax, pulmonary contusion, aspiration, haemorrhage and traumatic brain injury all become part of the immediate bedside differential for hypoxaemia.
A short neurology and critical appraisal update on factor XIa inhibition after recent non-cardioembolic ischaemic stroke or high-risk TIA. It frames asundexian as a potential dual-pathway prevention strategy when added to antiplatelet therapy, while keeping mechanism, trial population, bleeding outcomes, approval status and current practice separate.
Pre-hospital, HEMS and clinical leadership teams get a culture-focused episode on expert teams, psychological safety and sustainable service development. It links inclusive meetings, quieter voices, private feedback, difficult conversations, delegation, charity partnership and marginal gains to better trauma care.

Paediatric, emergency and acute-care clinicians get a high-value bronchiolitis review. It keeps clinical diagnosis, work of breathing, hydration, feeding, nasal suction and illness trajectory ahead of routine chest radiography, blood tests, blood gases, viral panels, bronchodilators and corticosteroids.
After intubating a major trauma patient, document peak pressure, plateau pressure, expired tidal volume and waveform pattern before changing multiple ventilator settings. Reassess pneumothorax, chest tube patency, suction, air leak behaviour and haemodynamics before escalating PEEP. In bronchiolitis, document work of breathing, feeding and wet nappies before ordering routine tests or adding medication.
In a ventilated trauma patient, what does high peak pressure with high plateau pressure suggest?
It suggests poor compliance or raised transthoracic pressure, including pneumothorax, abdominal compartment syndrome, pulmonary contusion or aspiration.
In a ventilated trauma patient with low peak pressure, low plateau pressure and expired tidal volumes much lower than set tidal volumes, what should be considered?
A major air leak should be considered, especially in the context of chest trauma and chest tube drainage.
In typical infant bronchiolitis, what bedside features should drive escalation more than an isolated oxygen saturation?
Increasing work of breathing, fatigue, perfusion, feeding volume, wet nappies and overall clinical trajectory should drive escalation.
