ABSTRACT
The primary function of the respiratory system is to provide oxygen and remove carbon dioxide; consequently, a rise in respiratory rate will occur in response to illnesses in both the lungs and in other body systems. Physiological adaptations to the respiratory system in pregnancy occur in response to the increased oxygen requirements of mother and fetus. Respiratory assessment will form part of an overall assessment of the woman, which will encompass ABCDE assessment alongside traditional midwifery head-to-toe examination. Asthma is a chronic inflammatory disorder of the respiratory system, characterised by episodic breathlessness, wheezing, shortness of breath, excessive production of mucus, cough and a sensation of tightness in the chest. Influenza is a contagious respiratory illness caused by influenza viruses. Outbreaks of influenza occur seasonally and more serious pandemic flu occurs periodically. Pneumonia is an inflammation of the lungs caused by microorganisms, usually bacteria or viruses.
