    Study Notes

    Tachycardia

    • Tachycardia can manifest as palpitations
    • The goal of treating tachycardia is to restore a normal heart rate and rhythm

    Oxygen Therapy

    • Supplemental oxygen may be required for clients with cardiopulmonary issues to increase oxygenation of the body tissues
    • The preferred method for delivering oxygen to most clients is through a nasal cannula
    • A simple face mask can cause CO2 retention and respiratory acidosis, which can lead to respiratory failure
    • Nurses should be aware of potential skin breakdown when using nasal cannulas for oxygen delivery due to prolonged pressure on the skin
    • A partial rebreather mask has a reservoir bag that stores oxygen, whereas a simple face mask does not
    • The purpose of a CPAP (continuous positive airway pressure) device in respiratory therapy is to increase airway pressure and keep airways open
    • BiPAP (bilevel positive airway pressure) is primarily recommended for use in conditions such as chronic obstructive pulmonary disease (COPD) and pneumonia
    • Oxygen containers should not be stored in an enclosed space like a closet as it can lead to explosion or fire
    • A potential manifestation of acute oxygen toxicity affecting the central nervous system is seizures

    Safety Precautions in Oxygen Therapy

    • "No Smoking" and "Oxygen in Use" signs should be posted inside and outside the home when oxygen therapy is being used
    • Bedding should be 100% cotton when oxygen is used while sleeping to reduce the risk of fire
    • Oxygen concentrators should be kept several inches away from curtains or walls to reduce the risk of fire
    • Flammable substances should never be placed on the upper chest or face of a client using oxygen therapy
    • A fire extinguisher should be kept nearby in case of a fire hazard when using oxygen therapy at home
    • Oxygen containers should be attached to a fixed object to prevent them from being knocked over or falling

    Hypoxemia and Hypoxia

    • The primary cause of hypoxemia is inadequate oxygenation of the blood
    • A common manifestation of hypoxemia and hypoxia is shortness of breath
    • Intercostal retractions indicate respiratory distress
    • Hypoxemia is a state of low oxygen levels in the blood, whereas hypoxia is a state of low oxygen levels in the tissues

    Respiratory Imbalance

    • Hyperventilation can cause respiratory alkalosis, which can lead to a decrease in carbon dioxide (CO2) levels in the blood
    • The primary effect of hypoventilation on the client's blood is an increase in CO2 levels
    • The primary cause of alkalosis in a client experiencing hyperventilation is a decrease in CO2 levels
    • A common symptom of alkalosis caused by hyperventilation is numbness or tingling in the hands and feet
    • Acidosis caused by hypoventilation can lead to an increase in hydrogen ions in the blood
    • A common symptom of acidosis caused by hypoventilation is headache
