The Late-Phase Asthma Trap: How to Actually Escalate

Asthma attacks don't always hit immediately. The late-phase response can strike 4-12 hours after trigger exposure, driven by inflammatory cells slowly invading airway tissue — not just smooth muscle constriction. In this episode, we break down why standard "use your rescue inhaler" advice often fails, how the SMART approach (single-inhaler maintenance and reliever therapy) addresses the gap, and a practical 4-phase escalation plan based on GINA 2024-2025 guidelines. We cover peak flow thresholds, when to start oral steroids (and when not to taper), and how anxiety creates a dangerous physiological feedback loop that a good plan must account for.
