    Study Notes

    Hypoxemia

    • A decrease in arterial oxygen tension in the blood is called hypoxemia.

    Manifestations of Hypoxemia

    • Cyanosis is NOT a manifestation of hypoxemia.

    Causes of Hypoxia

    • Hypoventilation, diffusion impairment, shunting, and reduced oxygen-carrying capacity can lead to hypoxia.

    Complications of Oxygen Therapy in COPD

    • Oxygen-induced hypercapnia is a complication of oxygen therapy in patients with Chronic Obstructive Pulmonary Disease (COPD).

    Inadequate Oxygen Delivery

    • Inadequate oxygen delivery due to extrinsic factors can result in tissue hypoxia.

    Late Stage Hypoxemia Sign

    • Mental confusion indicates a late stage of hypoxemia.

    Oxygen Administration Method to Avoid in COPD

    • Oxygen administration methods exceeding 2 LPM should be avoided in COPD patients using a partial rebreathing mask.

    Oxygen Free Radical Overproduction

    • Retinopathy is a symptom related to overproduction of oxygen free radicals from supplementary O2.

    Partial Rebreathing Mask Characteristics

    • A partial rebreathing mask rebreathes approximately 50% of exhaled air.
    • The minimum flow rate required for a partial rebreathing mask is 5 to 10 LPM.
    • A significant advantage of a partial rebreathing mask is its ability to deliver higher concentrations of oxygen compared to a simple mask.

    Partial Rebreathing Mask Use Guidelines

    • When using an oxygen mask continuously, the reservoir bag should be checked every 2 to 3 hours.
    • The main risk associated with a partial rebreathing mask is the possibility of rebreathing exhaled CO2.

    Non-Rebreathing Mask Features

    • The one-way valves in a non-rebreathing mask prevent inhalation of atmospheric air.
    • A non-rebreathing mask can deliver an oxygen concentration as high as 95%.

    Non-Rebreathing Mask Safety Precautions

    • Oil-based lubricants should not be used around the mask to avoid inhalation risks.

    Oxygen Toxicity

    • Prolonged high-concentration oxygen therapy can lead to oxygen toxicity.
    • The recommended best prevention method for oxygen toxicity is limiting the FiO2.
    • Dyspnea, substernal chest pain, and non-productive cough are symptoms of oxygen toxicity.

    Oxygen Therapy Systems

    • High-flow oxygen therapy systems include Venturi masks, nasal cannulas, and face tents.
    • The primary purpose of a flowmeter in oxygen therapy is to regulate the oxygen flow rate.
    • Low-flow oxygen therapy systems include simple masks, partial rebreathing masks, and non-rebreathing masks.

    Effects of High Oxygen Exposure

    • High oxygen exposure in infants can have neurological effects due to retrolental fibroplasia.

    Oxygen Toxicity Symptoms

    • Dyspnea is a symptom of oxygen toxicity.

    Nasal Cannula Use

    • The primary use of a nasal cannula is for low-flow oxygen delivery.

    Simple Mask Disadvantages

    • A disadvantage of using a simple mask for oxygen delivery is its inability to deliver high concentrations of oxygen.
    • The oxygen concentration range delivered by a simple mask is 35% to 55%.
    • The efficiency of a simple mask can be affected by poor fitting or air leaks.

    Partial Rebreathing Mask Distinction

    • A partial rebreathing mask is distinguished by its reservoir bag, which allows some rebreathing of exhaled air.

    Oropharyngeal Catheter Characteristics

    • Oropharyngeal catheters are inserted into the mouth or nose and pass through the pharynx.

    Nasal Cannula Flow Rates

    • A typical flow rate for a nasal cannula is 2 to 6 LPM.

    Partial Rebreathing Mask Considerations

    • The primary consideration for using a partial rebreathing mask is the possibility of rebreathing exhaled CO2.

    Non-Rebreathing Mask Purpose

    • The primary purpose of using a non-rebreathing mask is to deliver high concentrations of oxygen.

    Non-Rebreathing Mask Reservoir Bag Monitoring

    • The reservoir bag of a non-rebreathing mask should be monitored for complete deflation, which indicates a leak.

    Oxygen Therapy Devices

    • A Venturi mask provides a precise concentration of oxygen using the Bernoulli principle.

    Venturi Mask Flow Rate

    • The flow rate for a Venturi mask is 4 to 15 LPM.

    Oxygen Therapy Purpose

    • The primary purpose of oxygen therapy is to increase oxygen levels in the blood.

    Face Tent Disadvantages

    • A disadvantage associated with the face tent oxygen device is its potential to irritate the skin.

    Respiratory System Function

    • Adequate ventilation is essential for the normal functioning of the respiratory system.

    Non-Rebreathing Mask Function

    • A non-rebreathing mask ensures that atmospheric air is not inhaled due to one-way valves.

    Non-Rebreathing Mask Reservoir Bag Deflation

    • If the reservoir bag of the non-rebreathing mask deflates completely, the flow rate should be increased.

    Respiratory Therapy

    • Mechanical ventilation is NOT classified as non-invasive respiratory therapy.

    Face Tent Oxygen Concentration

    • The oxygen concentration range delivered by a face tent is 30% to 50%.

    Oxygen Therapy Goals

    • One goal of oxygen therapy is to improve tissue oxygenation.

    Non-Rebreathing Mask Design

    • A non-rebreathing mask is specifically designed to prevent rebreathing of exhaled air.

    Oxygen Administration Systems Classification

    • Flow rate is NOT included in the classifications of oxygen administration systems.

    Oxygen Therapy Aim

    • Adequate oxygen therapy aims to reduce hypoxemia in patients.

    Hypoxemia Definition

    • In the context of oxygen therapy, hypoxemia refers to a low blood oxygen level.
