Acute Care & Support
The acute attack, oxygen and respiratory failure, and the pharmacology of quitting smoking.
The Acute Attack: Treating Asthma and COPD Flare-Ups
A severe asthma or COPD attack is a medical emergency, and the drugs used to treat it are almost all ones you've already met — just given faster, harder, and together. Learning the emergency sequence pulls the whole respiratory section together and shows how the pieces combine when a patient can't breathe.
Oxygen Is a Drug: Respiratory Failure & Controlled Oxygen
We rarely think of oxygen as a drug, but it is one — with a correct dose, real dangers if misused, and specific indications. The most counter-intuitive lesson in respiratory medicine lives here: in some patients, giving too much oxygen can be harmful. Understanding why unlocks how we treat the failing lung.
Smoking Cessation: The Most Powerful 'Respiratory Drug' of All
Stopping smoking does more for a person's lungs, heart and lifespan than any inhaler ever could — it's the single most effective intervention in respiratory medicine. And because nicotine is powerfully addictive, we have real pharmacology to help: three main approaches that make quitting genuinely achievable.
