Vital Signs and Measurements

Flashcards based on key terms and definitions regarding vital signs and respiratory conditions.

Sleep Apnea

A condition where airflow during respiration stops for more than 10 seconds, leading to accumulation of carbon dioxide and depletion of oxygen in the blood.

CPAP (Continuous Positive Airway Pressure)

A treatment for sleep apnea that provides pressure on the airway to keep it open during sleep.

Narcolepsy

A sleep disorder characterized by excessive sleepiness and frequent daytime sleep attacks, often accompanied by temporary paralysis.

Rales

Crackling or rattling sounds heard during inspiration and expiration when lung passageways contain secretions.

Rhonchi

Low-pitched snoring sounds heard continuously during inspiration and expiration, indicating obstruction or secretions in the airways.

Wheezes

High-pitched musical sounds usually heard on expiration, associated with obstruction in the bronchi.

Stridor

A crowing sound heard on inspiration due to an obstruction of the upper airway, often linked to conditions like laryngitis.

Stertorous Respiration

A snoring sound associated with labored breathing, typically due to partial obstruction of the upper airway.

Systole

The phase of the cardiac cycle when the heart contracts, exerting the highest pressure on arterial walls.

Diastole

The phase of the cardiac cycle when the heart relaxes, exerting the lowest pressure on arterial walls.
