Salbutamol: why it works. We give it as a puff from a blue inhaler, or as a nebuliser mist driven with oxygen when the patient is too breathless to coordinate their own breaths. But the mechanism never changes: 🔑 Binds to beta-2 receptors in airway smooth muscle 📈 Increases cAMP inside the cell ⬇️ Lowers calcium ➡️ Muscle relaxes, airways open, breathing improves It’s not magic. It’s molecular biology. Learn. Adapt. Respond. #Paramedic #Ambulance #Prehospital #MedicalEducation #Salbutamol #Ast
