Orthostatic hypotension

A drop in systolic blood pressure of at least 20 mmHg, or diastolic of at least 10 mmHg, within three minutes of standing, often causing dizziness and reflecting impaired cardiovascular compensation.

Related: Jugular venous distention, Mean arterial pressure
Jugular venous distention

Visible bulging of the neck veins when a patient reclines at roughly 30 to 45 degrees, suggesting elevated right-sided cardiac filling pressures and possible volume overload or heart failure.

Related: Pitting edema grading, Orthostatic hypotension
Ankle-brachial index

Ratio of ankle systolic pressure to brachial systolic pressure measured with a Doppler device; values below 0.90 suggest peripheral arterial disease and guide exercise and wound-care decisions.

Related: Pitting edema grading
Pitting edema grading

A scale from 1+ to 4+ describing how deeply a fingertip depression persists in dependent tissue, used to track fluid accumulation and response to diuretic or positioning interventions.

Related: Jugular venous distention
Tactile fremitus

A vibration felt through the chest wall when the patient speaks a repeated phrase, increased over consolidation and decreased over effusion, pneumothorax, or excess adipose tissue.

Related: Accessory muscle use, Pulse oximetry
Accessory muscle use

Visible contraction of sternocleidomastoid, scalene, or abdominal muscles during breathing, signaling increased work of breathing and possible impending respiratory fatigue or failure.

Related: Pursed-lip breathing, Pulse oximetry
FEV1/FVC ratio

The fraction of forced vital capacity exhaled in the first second; a reduced ratio supports obstructive lung disease, while a preserved or increased ratio suggests a restrictive pattern.

Related: Pursed-lip breathing, Six-minute walk test
Pulse oximetry

Noninvasive estimation of arterial oxygen saturation using light absorbance through a fingertip or earlobe; readings become inaccurate with poor perfusion, motion, nail polish, or abnormal hemoglobin species.

Related: Accessory muscle use
Incentive spirometry

A device-guided slow deep breath that sustains inflation of the lungs, used after surgery or during immobility to prevent atelectasis and encourage sustained maximal inspiration.

Related: Airway clearance therapy, Early mobilization
Airway clearance therapy

Techniques such as huff coughing, positive expiratory pressure, and oscillating devices that mobilize and expel secretions in patients with retained mucus or chronic suppurative lung disease.

Related: Pursed-lip breathing, Incentive spirometry
Pursed-lip breathing

A breathing pattern with a slow nasal inhale and prolonged exhale through narrowed lips, which reduces air trapping and dyspnea in obstructive lung disease.

Related: Airway clearance therapy, Accessory muscle use
Chest tube management

Monitoring and safeguarding a pleural drainage system, including checking for tidaling, air leaks, and output, and avoiding clamping or lifting the collection chamber above chest level.

Related: Incentive spirometry
MET

A unit expressing exercise intensity as multiples of resting oxygen consumption, roughly 3.5 milliliters of oxygen per kilogram per minute, used to describe activity levels and functional capacity.

Related: Borg Rating of Perceived Exertion, FITT principle
Borg Rating of Perceived Exertion

A subjective 6-to-20 or 0-to-10 scale measuring how hard a patient feels he or she is working during activity, commonly used to set and monitor exercise intensity.

Related: MET, Heart rate reserve
Heart rate reserve

The difference between maximal and resting heart rate; multiplying it by a target percentage and adding the resting rate yields a training heart rate for exercise prescription.

Related: Borg Rating of Perceived Exertion, FITT principle
Symptom-limited graded exercise test

A progressive treadmill or cycle protocol that raises workload until symptoms, arrhythmia, or safety criteria stop the test, establishing functional capacity and ischemic thresholds.

Related: ST-segment depression, MET
FITT principle

A framework organizing exercise prescription into frequency, intensity, time, and type, ensuring all components of an aerobic or resistance program are specified and adjusted over time.

Related: MET, Heart rate reserve
Six-minute walk test

A self-paced corridor walk measuring the greatest distance covered in six minutes, reflecting submaximal functional exercise capacity and used to track response to rehabilitation.

Related: Borg Rating of Perceived Exertion, FITT principle
ST-segment depression

Downward displacement of the ECG segment between the J point and the T wave, which may indicate myocardial ischemia, strain, or digitalis effect depending on shape and lead distribution.

Related: Symptom-limited graded exercise test, QT interval
Atrial fibrillation

An irregularly irregular supraventricular rhythm with absent P waves and a variable ventricular response, increasing stroke risk and often limiting exercise tolerance.

Related: ST-segment depression
QT interval

The ECG time from ventricular depolarization to repolarization, corrected for heart rate; prolongation raises risk of torsades de pointes, especially with certain medications or electrolyte imbalances.

Related: Atrial fibrillation
Mean arterial pressure

The average arterial pressure during a cardiac cycle, approximated as one-third systolic plus two-thirds diastolic pressure, reflecting organ perfusion and guiding vasopressor or fluid decisions.

Related: Orthostatic hypotension
Ventilator modes

Named strategies such as volume control or pressure support that determine how a ventilator delivers breaths, affecting work of breathing, sedation needs, and readiness for mobilization.

Related: Ventilator weaning (liberation), Early mobilization
ICU-acquired weakness

New symmetric limb weakness developing during critical illness without another cause, resulting from immobility, inflammation, and sedation, and managed with early mobilization and adequate nutrition.

Related: Early mobilization, Ventilator weaning (liberation)
Ventilator weaning (liberation)

The structured process of reducing ventilatory support and assessing spontaneous breathing to determine when a patient can sustain respiration without the artificial airway.

Related: Ventilator modes, ICU-acquired weakness
Early mobilization

Starting positioning, range of motion, sitting, and walking as soon as the patient is medically stable in critical care, reducing delirium, weakness, and length of stay.

Related: ICU-acquired weakness, Incentive spirometry
Motivational interviewing

A collaborative conversational style that evokes a patient's own reasons for change by exploring ambivalence and strengthening commitment, rather than persuading or advising directly.

Related: Stages of change, Self-efficacy
Teach-back method

Asking patients to restate instructions in their own words so the clinician can confirm understanding and correct gaps, rather than asking whether they understood.

Related: Health literacy, Motivational interviewing
Stages of change

A model describing progression through precontemplation, contemplation, preparation, action, and maintenance, helping clinicians match counseling strategies to a patient's readiness for behavior change.

Related: Motivational interviewing, Self-efficacy
Health literacy

A patient's capacity to obtain, process, and understand basic health information needed to make decisions, influenced by education, language, culture, and the complexity of written materials.

Related: Teach-back method
Self-efficacy

A person's confidence in his or her ability to perform a specific behavior successfully, a strong predictor of adherence to exercise and self-management programs.

Related: Motivational interviewing, Stages of change
Informed consent

The process of explaining the purpose, risks, benefits, and alternatives of an intervention and confirming voluntary agreement, respecting patient autonomy and documenting the discussion.

Related: Interprofessional collaboration
Evidence-based practice

Clinical decisions integrating the best available research, clinician expertise, and patient values and preferences, rather than relying on habit or tradition alone.

Related: Validity, Quality improvement (PDSA cycle)
Interprofessional collaboration

Team-based care in which professionals from different disciplines share goals, information, and decision-making to coordinate safe, efficient patient management.

Related: Informed consent, Quality improvement (PDSA cycle)
Validity

The degree to which an instrument or test measures what it is intended to measure, including content, criterion, and construct forms relevant to selecting outcome measures.

Related: Evidence-based practice
Quality improvement (PDSA cycle)

A structured, iterative method for testing small changes: planning an intervention, trying it, studying the results, and acting on findings to improve care processes.
