A carer has to be frequently aware of changes in patients’ illnesses. For example, if a person goes from being asleep to being unconscious, they will need an ambulance straightaway. If your observation skills are not up to standard, you won’t have any idea about the difference in the person’s condition. There are two kinds of observations: ones that are noticeable, for example amount of blood inside the urine, pulse rate, blood density and fever and the ones that you can spot, for instance whether the patient is light-toned or red-faced, aware or drowsy, depressed or cheerful, or eating well. The two observations are crucial when keeping a lookout on a patient’s general illness.
