Medical asepsis

Practices that reduce the number and spread of microorganisms, such as hand hygiene, gloves, and routine cleaning of surfaces. It does not destroy all spores and is used in everyday patient care.

Surgical asepsis

Techniques that keep an area or object completely free of all microorganisms, including spores. Used for sterile procedures such as dressing changes, catheter insertion, and injections.

Related: Medical asepsis, Sterile field, Personal protective equipment
Standard precautions

Infection-control measures applied to every patient regardless of diagnosis, including hand hygiene, gloves, gowns, masks, and safe handling of sharps and body fluids.

Related: Transmission-based precautions, Personal protective equipment, Needlestick safety
Transmission-based precautions

Extra precautions used when a specific pathogen spreads by contact, droplet, or airborne routes. They add gowns, masks, respirators, or private rooms on top of standard precautions.

Related: Standard precautions, Personal protective equipment, Chain of infection
Personal protective equipment

Barrier items worn to protect the worker and patient from exposure, including gloves, gowns, masks, respirators, and eye protection. Selection depends on the task and anticipated splash risk.

Related: Standard precautions, Surgical asepsis, Transmission-based precautions
Chain of infection

A model describing six linked elements needed for infection to spread: infectious agent, reservoir, exit portal, mode of transmission, entry portal, and susceptible host. Breaking any link prevents transmission.

Sterile field

A work area treated as free of all microorganisms. Only sterile items may touch it, and anything that contacts a nonsterile surface is considered contaminated.

Sterile glove technique

The method of putting on and removing sterile gloves without touching the outside of the gloves with bare hands, preserving sterility for procedures such as wound care.

Related: Sterile field, Surgical asepsis

The U.S. federal agency that sets and enforces workplace safety rules, including the bloodborne pathogens standard that governs exposure control in medical offices.

Related: Exposure control plan, Needlestick safety
Vital signs

Measurements of temperature, pulse, respiration, blood pressure, and often pain or oxygen saturation. They establish a baseline and reveal changes in a patient's condition.

Related: Blood pressure, Pulse, Respiration
Blood pressure

The force of blood against artery walls, recorded as systolic over diastolic pressure in millimeters of mercury. Measured with a cuff and stethoscope or an automated device.

Related: Vital signs, Pulse
Pulse

The rhythmic expansion of an artery with each heartbeat, counted for rate, rhythm, and strength. Common sites include the radial, brachial, and carotid arteries.

Related: Vital signs, Respiration
Respiration

The exchange of oxygen and carbon dioxide, assessed by counting breaths per minute and noting depth, rhythm, and effort without telling the patient you are counting.

Related: Vital signs, Pulse oximetry
Pulse oximetry

A noninvasive method using a sensor on a finger or earlobe to estimate the percentage of hemoglobin saturated with oxygen, helping detect low blood oxygen.

Related: Respiration, Vital signs
Body mass index

A screening number calculated from height and weight that estimates whether a person's weight is in a healthy range. It does not measure body fat directly.

Related: Anthropometric measurement
Anthropometric measurement

Objective measurements of the body such as height, weight, and head circumference, used to track growth and nutritional status and to calculate medication doses.

Related: Body mass index
Intake and output

Recording of all fluids a patient takes in and puts out, used to assess hydration, kidney function, and response to treatment. Output includes urine, vomit, and drainage.

Related: Urinalysis, Vital signs
Urinalysis

Physical, chemical, and microscopic testing of a urine sample to screen for infection, kidney disease, diabetes, and other conditions. Often performed in the office laboratory.

Related: Intake and output, Specimen collection
Specimen collection

Obtaining and labeling body fluid or tissue samples for laboratory testing. Correct patient identification, container, timing, and labeling are essential to valid results.

Related: Urinalysis, Chain of custody
Chain of custody

A documented record of who collected, handled, and stored a specimen or sample at each step, ensuring legal integrity for drug testing and forensic purposes.

Related: Specimen collection
Venipuncture

Puncturing a vein with a needle to draw blood or start an infusion. It requires site selection, aseptic technique, correct tube order, and proper labeling.

Related: Phlebotomy order of draw, Specimen collection
Phlebotomy order of draw

The sequence in which blood collection tubes are filled to prevent additive carryover between tubes. Following the correct order protects test accuracy and reduces contamination.

Related: Venipuncture, Specimen collection
Capillary puncture

Collecting a small blood sample by pricking a fingertip or heel. Used for glucose checks, hemoglobin, and newborn screening when venous access is not needed.

Related: Venipuncture, Specimen collection
Electrocardiogram

A recording of the heart's electrical activity through electrodes placed on the skin. It helps detect arrhythmias, ischemia, and other cardiac conditions.

Related: Holter monitor, Vital signs
Holter monitor

A portable device worn for 24 to 48 hours that continuously records the heart's electrical activity, capturing irregular rhythms that a brief office tracing might miss.

Related: Electrocardiogram
