Oxygenation & Thermoregulation

This set of flashcards covers key vocabulary and concepts related to oxygenation and thermoregulation in nursing, including definitions and important clinical terms.

Oxygenation

The process of providing oxygen to body tissues for proper functioning.

Thermoregulation

The body's ability to maintain a stable internal temperature.

Pulmonary ventilation

The process of breathing, which includes inhalation and exhalation.

Hypoxemia

Reduced oxygen levels in the blood.

Dyspnea

Difficult or labored breathing.

Hyperthermia

A condition of elevated body temperature due to excessive heat production or exposure.

Pyrexia

A body temperature above the usual range, typically greater than 100.4°F (38°C).

Hypothermia

A condition where core body temperature drops below 96°F (36°C).

Kussmaul breathing

Deep, labored breathing pattern associated with severe metabolic acidosis.

Cheyne-Stokes respirations

A pattern of breathing characterized by alternating periods of apnea and hyperventilation.

Factors affecting respiratory function

Age, environment, lifestyle, health status, medications, psychological factors.

Signs of hyperthermia

Excessive sweating, pale skin, dizziness, nausea, rapid weak pulse.

Nursing process for oxygenation

Assess, Analyze, Plan, Implement, Evaluate.

Core temperature

The temperature of deep tissues in the body; remains relatively constant.

Surface temperature

The temperature of the skin and subcutaneous tissues, affected by environmental factors.

Nursing interventions for fever

Monitor vital signs, provide fluids, administer antipyretics, reduce physical activity.

Conditions affecting airway obstruction

Upper airway obstruction and lower airway obstruction.

Factors influencing heat loss

Evaporation, convection, radiation, conduction.
