Chronic Obstructive Pulmonary Disease (COPD) is a non-reversible, progressive airflow obstruction, caused by inflammatory damage to lung tissue (e.g. from tobacco smoking). This makes the lungs harder to ventilate and more vulnerable to infection.

Hypertension is persistently raised arterial blood pressure. It can also be defined as the level of blood pressure above which treatment does more good than harm, so thresholds vary. In this article we'll go through diagnosis of hypertension, causes, and differentiate primary and secondary hypertension.

Anaphylaxis is a severe, life-threatening, generalised or systemic hypersensitivity reaction (Type 1).
You can recognise anaphylaxis based on:
- sudden onset and rapid progression of symptoms
- airway and/or breathing and/or circulation problems
- skin and/or mucosal changes (flushing, urticaria or angioedema) but these may be absent in up to 20% of cases
DVTs occur when a blood clot develops in the major deep veins. It commonly occurs in the leg, thigh, pelvis or abdomen, but can occur less commonly in the arms, or portal system. This article will focus on DVT in the lower extremities. DVTs can cause pulmonary embolisms which can be fatal.
Pulmonary embolism occurs as a result of a blood clot forming in the deep veins which then embolises (breaks off) and becomes lodged in the pulmonary arteries. This can be a life-threatening event. The blood clot can block pulmonary circulation and put strain on the right side of the heart.
