Vital Signs Basics

Vital signs are objective measurements of the body's most basic functions.
They provide essential information about a patient's current health status.
Commonly measured vital signs include temperature, pulse rate, respiratory rate, and blood pressure.
Occasionally, pain assessment should also be included in the vital sign assessment.
Continuous and accurate monitoring of vital signs is crucial for the prompt diagnosis and effective treatment of various medical conditions.
Vital signs provide a baseline for comparison throughout a patient's care.

Temperature

Temperature is measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
Normal oral temperature in adults is typically between 36.5°C (97.7°F) and 37.5°C (99.5°F).
Variations in temperature can be caused by factors such as illness, stress, and time of day.
Methods for measuring temperature include oral, rectal, axillary, and temporal artery.
The oral method is frequently preferred for convenience, but rectal and temporal artery methods may be more accurate in certain situations.

Pulse Rate

Pulse rate refers to the number of heartbeats per minute.
A normal pulse rate for adults averages around 60-100 beats per minute.
A rapid pulse (tachycardia) or slow pulse (bradycardia) may indicate underlying medical issues.
The pulse is commonly assessed at the radial artery, but other sites may be used as needed.
Factors influencing pulse rate include age, activity level, and underlying medical conditions.

Respiratory Rate

Respiratory rate measures the number of breaths per minute.
A normal respiratory rate for adults is typically 12 to 20 breaths per minute.
Changes in respiratory rate can signal respiratory distress or other medical complications.
Observations of breathing patterns (e.g., shallow, rapid, labored) can be important elements in assessing respiratory health.

Blood Pressure

Blood pressure measures the force exerted by blood against the arterial walls.
It is recorded as two numbers: systolic pressure (the highest pressure) and diastolic pressure (the lowest pressure).
A normal blood pressure for adults is typically less than 120/80 mmHg.
High blood pressure (hypertension) and low blood pressure (hypotension) can indicate various health conditions.
Factors affecting blood pressure include posture, activity level, emotional state, and certain medications.
Equipment utilised to measure blood pressure, such as sphygmomanometers, are critical to measuring blood pressure accurately.

Measurement Techniques

Proper technique for each vital sign measurement is essential for accurate readings and patient safety.
Consistency is key in technique and location of measurement.
Incorrect measurements can lead to poor diagnoses or inappropriate treatments.

Factors Affecting Vital Signs

Various factors can influence vital signs, including activity level, medications, stress, and environmental conditions.
A thorough medical history and a patient's general condition should be considered before interpreting vital signs.

Interpretation of Vital Signs

Interpreting vital signs involves comparing measurements to established norms and considering the patient's individual factors, such as age and underlying health conditions.
Significant deviations from expected values may warrant further investigation and possible interventions.
A detailed understanding of the patient's health history is essential to contextually understand variations that may normally occur.
