Medical specialists use maths. They must obtain reliable data and calculations to prevent, diagnose and treat medical problems.
Some example of how they use maths are: monitoring our ‘Vital signs’ — temperature, pulse rate, breathing rate and blood pressure. These indicators are graphed and can be used to show something ‘changing’ which may indicate a deterioration of one’s health.
Calculation of dosages, i.e. the amount of medication one needs to receive.
Imaging: X-Rays and CAT scans require mathematics.
Research: Scientists build mathematical models to predict how the human body can fight a disease.
