VITAL SIGNS

Vital Signs (VS)

Assessment that provides information on thermoregulatory, respiratory, and cardiovascular status.

Cardiac Output (CO)

Amount of blood the heart pumps in one minute, calculated by heart rate (HR) times stroke volume (SV).

Pyrexia

A medical term for fever, which occurs when heat-loss mechanisms are unable to keep pace with excess heat production.

Tachycardia

An abnormally fast heart rate of greater than 100 beats per minute.

Bradycardia

A slow heart rate of less than 60 beats per minute.

Eupnea

Normal, effortless breathing with a rate of 12-20 breaths per minute for adults.

Hypoxia

Inadequate tissue oxygenation at the cellular level.

Hypoxemia

Below normal level of oxygen in the blood, specifically in the arteries.

Thermoregulation

The process by which the body maintains its internal core temperature.

Apical Pulse

The pulse assessed by auscultation at the apex of the heart, typically used for a full 60 seconds.

Oxygen Saturation (SpO2)

The ratio of oxygen in the blood that is combined with hemoglobin, indicating oxygenation status.

Respiratory Rate

The number of breaths taken in one minute, which is normal at 12-20 for adults.

Arrhythmia

An irregular heart rhythm that can lead to inadequate cardiac output.

Hypothermia

Occurs when the core body temperature drops below 36°C.

Hyperventilation

Rapid and deep respirations that may result in decreased carbon dioxide levels.

Body Mechanics

The way in which the body moves and maintains balance during activities.

Documentation

The process of recording client care activities and findings for legal and communication purposes.

Hypovolemia

A state of decreased blood volume which can lead to decreased blood pressure.

Pulse Deficit

The difference between the apical and radial pulse rates, indicating potential cardiovascular issues.

Homeostasis

The body's ability to maintain stable internal conditions despite changes in the external environment.

Blood Pressure (BP)

The force exerted by circulating blood on the walls of blood vessels.

Pulse Pressure

The difference between systolic and diastolic blood pressure, indicating the health of the cardiovascular system.

Capillary Refill Time

The time taken for capillaries to refill after being compressed, indicating peripheral circulation.

Oximetry

A non-invasive method to measure oxygen saturation in the blood.

Cardiac Rhythm

The pattern of electrical impulses that trigger heartbeats, affecting heart function.

Respiratory Distress

A condition characterized by difficulty breathing and inadequate ventilation.

Shock

A life-threatening condition wherein blood flow is insufficient to supply oxygen to organs.

Sepsis

A life-threatening organ dysfunction caused by a dysregulated host response to infection.

Fluid Balance

The maintenance of the proper amount and distribution of fluid in the body.

Vital Capacity

The maximum amount of air that can be exhaled after a maximum inhalation.

Bradycardia

A slow heart rate of less than 60 beats per minute.

Tachycardia

An abnormally fast heart rate of greater than 100 beats per minute.

Importance of Vital Signs

Vital signs are essential indicators of a patient's health status and help identify potential health issues.

Normal Temperature Range

Normal body temperature is typically around 36.1°C to 37.2°C (97°F to 99°F).

Normal Heart Rate

A normal resting heart rate for adults ranges from 60 to 100 beats per minute.

Normal Respiratory Rate

The normal respiratory rate for adults is 12-20 breaths per minute.

Normal Blood Pressure

Normal blood pressure is generally defined as 120/80 mmHg.

Consequences of Hypoxia

Hypoxia can lead to cellular damage, organ dysfunction, and can be life-threatening if not addressed.

Assessment of Capillary Refill

Capillary refill time should be less than 2 seconds to indicate adequate blood circulation.

Definition of Sepsis

Sepsis is a severe response to infection causing systemic inflammation and organ dysfunction.

Role of Body Mechanics

Proper body mechanics help prevent injury and promote efficiency while performing activities.

Signs of Shock

Signs of shock may include rapid heartbeat, low blood pressure, pale skin, and confusion.

Menopause

The time in a woman's life when menstrual cycles cease permanently, typically occurring in midlife.

Osteoporosis

A condition characterized by weakened bones, increasing the risk of fractures.

Hypertension

A condition of abnormally high blood pressure, often leading to health complications.

Diabetes Mellitus

A chronic disease characterized by high levels of sugar in the blood due to insulin resistance or deficiency.

Stroke

A medical emergency that occurs when blood flow to the brain is interrupted, leading to brain damage.

Asthma

A chronic condition affecting the airways, causing difficulty in breathing due to inflammation and obstruction.

Cholesterol

A waxy substance found in the blood, important for health but can be harmful in high levels.

Allergy

A hypersensitive reaction to substances (allergens) that are normally harmless.
