VTS (ECC) key terms

The process of rapidly sorting patients by urgency so that life-threatening problems are treated first. It relies on brief visual assessment and vital signs rather than a full examination or diagnosis.

Adequate delivery of blood, and therefore oxygen and nutrients, to tissues. Bedside indicators include mucous membrane color, capillary refill time, heart rate, pulse quality, and mentation.

The seconds required for color to return to a blanched gum surface after digital pressure. Prolonged refill suggests poor perfusion or vasoconstriction; very rapid refill may suggest vasodilation.

The hue of the gums or conjunctiva used as a quick perfusion and oxygenation clue. Pale, white, blue, brick red, or muddy colors each point toward different circulatory or respiratory problems.

A state of inadequate tissue oxygen delivery caused by problems such as low blood volume, poor pump function, vasodilation, or obstruction. It is recognized by altered mentation, poor pulses, and abnormal mucous membranes.

Rapid administration of replacement fluids to restore circulating volume in a patient with shock. Isotonic crystalloids or colloids are given in boluses while perfusion, lung sounds, and mentation are reassessed.

A clear fluid containing dissolved electrolytes that moves freely between blood vessels and tissue spaces. Balanced isotonic solutions are commonly used for maintenance and for volume replacement in emergency patients.

A fluid containing large molecules that stay in the bloodstream longer than crystalloids and help hold water within vessels. Natural or synthetic colloids may be used in some shock or low-protein states.

A complication of excessive or too-rapid fluid therapy marked by serous nasal discharge, cough, tachypnea, crackles, or weight gain. It requires slowing or stopping fluids and notifying the veterinarian.

The force exerted by blood against vessel walls, commonly measured in emergencies by Doppler or oscillometric methods. Hypotension is a key sign of poor perfusion and a target for therapy.

Supplemental oxygen delivered by mask, nasal cannula, flow-by, oxygen cage, or hood to raise blood oxygen content. It is used for dyspnea, cyanosis, and other hypoxic states.

A noninvasive method that estimates arterial oxygen saturation using a sensor on a clipped area such as the tongue or toe. Readings can be affected by poor perfusion and motion.

Continuous measurement of carbon dioxide in exhaled gas, displayed as a waveform. It helps confirm endotracheal tube placement, monitor ventilation, and detect return of spontaneous circulation.

The organized response to cardiac arrest, combining chest compressions, ventilation, drug therapy, and rhythm checks. High-quality compressions with minimal interruptions are the priority.

Sudden loss of effective heart function that stops circulation. It is recognized by unresponsiveness, absent pulses, apnea, and absent heart sounds, and it requires immediate resuscitation.

Rhythmic compression of the chest in a lateral or dorsal position to generate forward blood flow during arrest. Compressions are delivered at a set rate and depth with brief pauses for rhythm checks.

The reappearance of a palpable pulse and effective heartbeat after resuscitation efforts. It is often accompanied by a sudden rise in exhaled carbon dioxide and guides post-arrest care.

Placement of a tube through the mouth into the trachea to secure an airway and allow ventilation. Tube position is checked by watching chest movement, listening, and ideally by capnography.

A blue or purple tint to mucous membranes caused by low oxygen levels in the blood. It is a late sign and may be hidden by anemia or poor lighting.

Difficult or labored breathing that a patient may show through an extended neck, open-mouth breathing, or abdominal effort. It signals a need for oxygen and prompt veterinary assessment.

Accumulation of fluid within the lung air spaces that impairs gas exchange and causes cough, tachypnea, and crackles. It can result from heart failure, fluid overload, or other causes.

A scoring tool that grades level of consciousness, motor activity, and brainstem reflexes to quantify neurologic status after head trauma. Lower scores indicate more severe injury.

The patient's level of awareness and responsiveness, ranging from alert and appropriate to obtunded, stuporous, or comatose. It is a core vital sign in triage and resuscitation.

Damage to the brain from blunt or penetrating trauma, often with altered mentation, pupils, and breathing patterns. Care aims to maintain blood pressure, oxygenation, and avoid raising intracranial pressure.

A life-threatening condition in which the stomach distends with gas and twists, obstructing outflow and impairing blood return to the heart. It presents with retching, abdominal distension, and shock.

Loss of blood from vessels, either externally or into body cavities. It can cause shock and anemia and may require pressure, fluids, transfusion, or surgical control.

Administration of whole blood or a blood component to replace red cells, clotting factors, or plasma proteins. Reactions such as fever, hemolysis, or allergic signs must be watched for closely.

A laboratory test that checks donor and recipient blood for compatibility before transfusion. It helps prevent hemolytic reactions, especially in previously transfused animals.

An adverse response to transfused blood, such as fever, hemolysis, hives, or breathing difficulty. The transfusion is stopped and the veterinarian notified while supportive care is given.

A severe, rapidly developing allergic reaction with signs such as collapse, vomiting, swelling, or breathing difficulty. It is treated emergently with epinephrine and supportive care.

A life-threatening organ dysfunction caused by a dysregulated response to infection. It presents with fever or low temperature, tachycardia, poor perfusion, and can progress to shock.

Ongoing assessment of vital parameters during sedation or anesthesia, including heart rate, rhythm, blood pressure, oxygenation, ventilation, and depth. Trends matter more than single readings.

Systematic evaluation of a patient's discomfort using behavior, posture, facial expression, and response to touch. It guides analgesic choice and reassessment in emergency and postoperative patients.

The legal, chronological documentation of a patient's care, including findings, treatments, and communications. Entries must be objective, timely, dated, and signed by the person making them.

The client's agreement to a procedure after receiving an explanation of its purpose, risks, benefits, and alternatives. It is documented in the record before care is provided.

The professional relationship among the veterinarian, the animal owner, and the patient that underlies care and legal responsibility. It generally requires that the veterinarian has assumed responsibility for the animal.

The professional duty to protect client and patient information from unauthorized disclosure. It applies to records, conversations, and images, with limited legal exceptions.

An infectious disease that can be transmitted from animals to people. Veterinary staff reduce risk through hand hygiene, protective equipment, and client education.

Practices that prevent spread of infectious agents in the hospital, including cleaning, disinfection, isolation, and traffic control. These measures protect patients, staff, and clients.

The routine cleaning of hands with soap and water or alcohol-based rub at defined moments of patient contact. It is the single most effective way to reduce hospital-acquired infection.

Barrier items such as gloves, gowns, masks, and eye protection worn to reduce exposure to infectious agents, chemicals, or radiation. It is selected based on the task and hazard.

Ongoing professional learning required to maintain credentialing and update skills. It may include conferences, courses, journal reading, and hands-on workshops.

The process by which a regulatory body verifies and grants authority to practice or use a professional title. It typically involves education, examination, and maintenance requirements.

The range of tasks and duties a technician may legally perform, as defined by state or provincial law and supervision requirements. It varies by jurisdiction and must be followed.

A credentialed technician who has met advanced education, experience, and examination requirements in a recognized discipline such as emergency and critical care. The title is granted by a specialty academy.

A standardized rating of an animal's fat cover and muscle mass, usually on a five- or nine-point scale. It is used to assess nutrition and track changes over time.

Objective measurements such as temperature, pulse, respiration, and weight that reflect a patient's physiologic state. They are recorded at each visit and compared with prior values.
