  • Asthma and Rhinits drugs
  • Respiratory Investigations
  • How to interpret ABGs
  • Respiratory conditions

What this Module Involves

This module first covers the fundamental basic physiology that you need to know to understand the respiratory system. We go through the anatomy of the thorax, the factors controlling breathing rate and the principles of hypersensitivity. We then look at the most common drugs used in the treatment of asthma/COPD and rhinitis and the main investigations used which help to differentiate obstructive vs restrictive conditions. Finally we use this platform to understand the main respiratory conditions.

Contents

Section 1:
Background

To begin with, we need to understand how the anatomy of the thorax and the lungs. We then understand the mechanism of breathing and how this becomes influenced by obstructive and restrictive pathologies. We also study the 4 different types of hypersensitivity as these commonly lead to breathing problems.

Section 2: pharmacology

There are many drugs used today to treat asthma and COPD. It is important to understand how these work and their side effects. In addition we look at the drugs involved in treating rhinitis. Whilst many of these are over the counter medication, it is still important to understand their mechanism of action and potential side effects.

Section 3: Tests and investigations

We start with bedside tests like spirometry which are used to differentiate obstructive and restrictive conditions, followed by  learning how to interpret an ABG and understanding which conditions cause acidosis and alkalosis. We look at different imaging techniques used including chest x-ray, CT scan, bronchoscopy and lung biopsy and their indications.

Section 4:
conditions

In this section, start with head and neck conditions followed by the pathology and treatment of upper vs lower respiratory tract infections. We then cover the main obstructive and restrictive conditions before understanding the different types of lung cancers. Finally we focus on some acute vs chronic respiratory conditions and their management.
