Introduction to Gas Exchange and Perfusion

A series of flashcards designed to reinforce key concepts related to gas exchange and perfusion, essential for nursing practice.

Gas Exchange

The process of oxygen moving into the bloodstream and carbon dioxide being removed.

Perfusion

The delivery of oxygenated blood to tissues and the removal of waste products.

Diffusion

The process by which gases exchange at the alveolar capillary membrane.

Normal Respiratory Physiology

The processes involved in gas exchange, including ventilation and diffusion.

Vital Signs

Measurements of essential body functions, including heart rate, respiratory rate, blood pressure, and oxygen saturation.

Supplemental Oxygenation Devices

Devices used to deliver additional oxygen to patients to improve oxygen saturation.

SVC/IVC

Superior vena cava and inferior vena cava; vessels that return deoxygenated blood to the heart.

Hypoxemia

A condition characterized by low oxygen levels in the blood.

Tachypnea

Rapid breathing, often a sign of respiratory distress.

ECG or EKG

An electrocardiogram; a test that records the heart's electrical activity.

Echocardiogram

An ultrasound of the heart that creates images to assess heart function.

Arterial Blood Gases (ABG)

A blood test measuring oxygen and carbon dioxide levels to determine lung function.

Homeostasis

The maintenance of stable internal conditions in the body.

Continuous Monitoring

Ongoing assessment of a patient's vital signs and overall condition.

Signs of Impaired Gas Exchange

Symptoms such as abnormal breath sounds, low oxygen saturation, and dyspnea.

Priority Assessment Findings

Critical signs that indicate the need for immediate medical intervention.
