Vital signs are critical indicators of a patient’s basic physiology. Oxygen saturation, respiratory rate, pulse rate, blood pressure and temperature are monitored regularly in many healthcare settings. Knowing how to measure, record and report these observations in an accurate way is an important skill in the development of practical patient care skills. A nursing certificate can enable students to gain an understanding of these processes and how they apply to the normal monitoring of patients.
Understanding the main vital signs
All of the vital signs are indicators of a patient’s condition. Temperature can give us clues as to changes that occur with infection or other conditions. Pulse rate is a measure of the activity of the heart and respiratory rate is a measure of the rate of breathing.
Blood pressure tells about the blood pressure in the arteries. O2 saturation percentage is the percentage of haemoglobin carrying oxygen in the blood. Combined, these can give useful clues to health care providers regarding changes in a patient’s condition.
Accurate Measurement Matters
Accurate measurement is essential to the usefulness of vital signs. Buildings, equipment placement, equipment positioning, equipment moves, improper positioning, and lack of proper procedures can impact readings.
Students should be taught the appropriate method for operating common monitoring equipment and applying appropriate clinical procedures. Standardised procedures to measure also enable comparisons to be made with data collected at various times.
Identifying changes in the condition of the patient
An abnormal reading does not necessarily give a complete picture of a patient’s health. Health care providers take the measurement as part of their assessment of symptoms, medical history, previous measurements, and other clinical factors.
When there is any major or unusual change, however, it may be necessary to evaluate such further. The ability to detect and report changes in a timely fashion is therefore a key part of patient monitoring.
Record and report observations
Documentation is an integral component of clinical care. Vital signs should be taken as per the healthcare facility’s procedures, and the appropriate time and measurement recorded.
Clear records enable members of the health care team to track trends and share information on significant changes. Failing to get a patient’s condition documented properly or accurately can make it harder to see how a patient’s condition has evolved over time.
Knowing the part the equipment plays
Various healthcare settings use digital thermometers, automated blood pressure monitor, pulse oximeter, etc. for monitoring. Students should be aware of the fundamentals of its function and its suitable application.
The training should also include checking the condition of equipment, following manufacturer/organisational instructions, and reporting any equipment concerns as appropriate. These practices help ensure accurate observations and patient safety.
The link between Monitoring and Patient Safety
Monitoring vital signs is not an ordinary job. Successful observations can help identify early signs of change in need of clinical intervention. They also make information available which can aid communication between various members of the healthcare team.
A nursing certificate can give learners a glimpse of these basic practices and help them understand the significance of accuracy, observation, documentation and timely reporting.
A good understanding of vital-sign monitoring is essential for future health care workers to gain knowledge of the importance of basic clinical observation in leading to organised, responsive and patient-centred care.
