Paramedic: Core Terms and Definitions

This is about providing clarity on common paramedic terms, not a full medical textbook. We’ll focus on the terms you’ll hear every day in the field, from dispatch to the ER.

Airway

The passage through which air reaches the lungs. Maintaining a patent airway is the top priority in emergency medical care.

Example: “Ensure the patient has a patent airway by using the head-tilt/chin-lift maneuver.”

ALS (Advanced Life Support)

Advanced medical care, including intubation, IV medications, and cardiac monitoring. ALS interventions are provided by paramedics and other advanced providers.

Example: “Dispatch ALS to the scene for a patient experiencing cardiac arrest.”

BLS (Basic Life Support)

Basic medical care, including CPR, bleeding control, and splinting. BLS interventions are typically provided by EMTs and first responders.

Example: “The patient is receiving BLS care until ALS arrives.”

Bradycardia

A heart rate that is slower than normal (typically below 60 beats per minute). Bradycardia can indicate a serious underlying medical condition.

Example: “The patient is showing signs of bradycardia, with a heart rate of 45.”

Capnography

The measurement of carbon dioxide (CO2) in exhaled breath. Capnography is used to assess ventilation and perfusion.

Example: “Apply capnography to monitor the patient’s respiratory status.”

Chief Complaint

The patient’s primary reason for seeking medical attention. The chief complaint guides the initial assessment and treatment.

Example: “The patient’s chief complaint is chest pain.”

Cyanosis

A bluish discoloration of the skin and mucous membranes, indicating a lack of oxygen. Cyanosis is a sign of severe respiratory distress.

Example: “The patient is exhibiting cyanosis around the lips and fingertips.”

Distal

Farther away from the point of attachment or origin. Important for describing location of injuries.

Example: “The patient has a distal radius fracture.”

Edema

Swelling caused by fluid accumulation in body tissues. Edema can be a sign of various medical conditions, including heart failure and kidney disease.

Example: “The patient is experiencing edema in the lower extremities.”

GCS (Glasgow Coma Scale)

A standardized scale used to assess level of consciousness. The GCS evaluates eye opening, verbal response, and motor response.

Example: “The patient has a GCS score of 10, indicating moderate impairment.”

Hypoglycemia

Low blood sugar levels. Hypoglycemia can cause confusion, seizures, and loss of consciousness.

Example: “The patient is hypoglycemic, with a blood sugar of 60.”

Hypotension

Low blood pressure. Hypotension can be caused by dehydration, blood loss, or heart problems.

Example: “The patient is hypotensive, with a blood pressure of 90/60.”

Hypoxia

A deficiency of oxygen reaching the tissues of the body. Hypoxia can lead to organ damage and death.

Example: “The patient is hypoxic, with an oxygen saturation of 88%.”

IV (Intravenous)

Administering fluids or medications directly into a vein. IV access allows for rapid delivery of treatments.

Example: “Establish an IV line for fluid resuscitation.”

LOC (Level of Consciousness)

A patient’s awareness and responsiveness to their surroundings. Changes in LOC can indicate a serious medical problem.

Example: “The patient’s LOC is decreased; they are only responsive to painful stimuli.”

Medial

Toward the midline of the body. Used to describe locations of injuries and anatomical features.

Example: “The patient has a medial laceration on their left thigh.”

NPO (Nil Per Os)

Nothing by mouth. This order is given to patients who are at risk of aspiration or who require surgery.

Example: “The patient is NPO in preparation for surgery.”

Patent

Open and unobstructed. Usually refers to an airway or blood vessel.

Example: “Ensure the patient’s airway is patent before administering oxygen.”

Proximal

Closer to the point of attachment or origin. Used to describe the relative location of anatomical structures.

Example: “The patient has a proximal humerus fracture.”

Pulse Oximetry

A noninvasive method of measuring oxygen saturation in the blood. Pulse oximetry is used to assess respiratory function.

Example: “Apply pulse oximetry to monitor the patient’s oxygen saturation.”

SOB (Shortness of Breath)

Difficulty breathing or feeling like you can’t get enough air. A common symptom of respiratory and cardiac problems.

Example: “The patient is complaining of SOB.”

Tachycardia

A heart rate that is faster than normal (typically above 100 beats per minute). Tachycardia can be caused by stress, fever, or underlying medical conditions.

Example: “The patient is tachycardic, with a heart rate of 120.”

Tidal Volume

The amount of air that moves into and out of the lungs with each breath. Tidal volume is an important indicator of respiratory function.

Example: “Assess the patient’s tidal volume to ensure adequate ventilation.”

Vital Signs

Measurements of the body’s basic functions, including heart rate, blood pressure, respiratory rate, temperature, and oxygen saturation. Vital signs provide important information about a patient’s condition.

Example: “Obtain a full set of vital signs upon arrival at the scene.”

What a hiring manager scans for in 15 seconds

Hiring managers quickly assess a candidate’s grasp of paramedic terminology. They want to see that you speak the language of emergency medicine fluently.

Clear and concise communication: Can you explain complex medical concepts simply?
Correct usage of terms: Do you use medical terms accurately and appropriately?
Understanding of pathophysiology: Do you understand the underlying mechanisms of disease and injury?
Clinical decision-making: Can you apply your knowledge of medical terminology to make sound clinical decisions?

The mistake that quietly kills candidates

Using vague or incorrect medical terminology can be a major red flag. It suggests a lack of knowledge and experience, and can undermine your credibility.

Instead of saying: “The patient was having trouble breathing.”
Say: “The patient was exhibiting signs of respiratory distress, including SOB and an oxygen saturation of 90%.”

FAQ

What is the difference between hypoxia and hypoxemia?

Hypoxia refers to a deficiency of oxygen reaching the tissues of the body, while hypoxemia refers to a deficiency of oxygen in the blood. Hypoxemia can lead to hypoxia, but hypoxia can also occur even when blood oxygen levels are normal, such as in cases of carbon monoxide poisoning.

What are the normal ranges for vital signs?

Normal ranges for vital signs vary depending on age, medical conditions, and other factors. However, general guidelines are: heart rate 60-100 bpm, blood pressure 90/60-120/80 mmHg, respiratory rate 12-20 breaths per minute, temperature 97.8-99.1Â°F, and oxygen saturation 95-100%.

Why is it important to use standardized medical terminology?

Using standardized medical terminology ensures clear and consistent communication among healthcare providers. This reduces the risk of errors and misinterpretations, and improves patient safety.

What is the significance of the Glasgow Coma Scale (GCS)?

The GCS is a standardized tool used to assess a patient’s level of consciousness. It evaluates eye opening, verbal response, and motor response, and provides a numerical score that indicates the severity of brain injury. A higher score indicates better neurological function.

What is the difference between ALS and BLS?

ALS (Advanced Life Support) involves advanced medical procedures such as intubation, IV medications, and cardiac monitoring, typically performed by paramedics. BLS (Basic Life Support) involves basic interventions like CPR, bleeding control, and splinting, usually provided by EMTs and first responders. ALS builds upon BLS.

What is the role of capnography in emergency medical care?

Capnography measures the level of carbon dioxide in exhaled breath. It helps paramedics assess the effectiveness of ventilation and perfusion. It can also detect early signs of respiratory distress or airway obstruction.

How do I accurately document medical terminology in patient care reports?

Use precise and standardized medical terms. Avoid abbreviations unless they are universally accepted. Describe your findings objectively and avoid subjective interpretations. Ensure your documentation is clear, concise, and accurate.

What are some common mistakes to avoid when using medical terminology?

Avoid using vague or ambiguous terms. Double-check the spelling of medical terms. Do not use abbreviations that are not universally recognized. Always use the correct term for the specific condition or treatment.

How can I improve my understanding of medical terminology?

Study medical terminology textbooks and online resources. Practice using medical terms in clinical settings. Review patient care reports and pay attention to the terminology used by experienced paramedics. Attend continuing education courses on medical terminology.

What is the importance of knowing directional terms like proximal and distal?

Directional terms like proximal and distal are essential for accurately describing the location of injuries and anatomical structures. This helps other healthcare providers understand the extent and nature of the patient’s condition. For example, knowing if a fracture is proximal or distal helps surgeons plan the appropriate treatment.

Why is it important to identify the patient’s chief complaint accurately?

The patient’s chief complaint is their primary reason for seeking medical attention. Identifying it accurately guides the initial assessment and treatment. It helps paramedics prioritize their interventions and focus on the most pressing issues.

How does understanding medical terminology impact patient care?

A strong understanding of medical terminology allows paramedics to communicate effectively with other healthcare providers, accurately document patient information, and make sound clinical decisions. This ultimately leads to better patient outcomes and improved safety.
