Flashcards

What is oxygen therapy?

Oxygen therapy is the administration of oxygen at a higher concentration than what is found in the air we breathe.

Why is oxygen therapy used?

Oxygen therapy is used to increase oxygen levels in the blood when they are too low due to illness or injury.

What is oxygen?

Oxygen is a colorless, odorless, and tasteless gas that is essential for human life.

What is a nasal cannula?

Nasal cannula is a device that delivers oxygen through the nostrils.

What is a non-rebreather mask?

A non-rebreather mask is a tight-fitting mask with a one-way valve that allows oxygen to enter but prevents exhaled air from mixing with the oxygen, providing the highest oxygen concentration.

Nasal Cannula

A device that delivers oxygen directly into the nostrils. It can be used for low-flow oxygen delivery (up to 6 L/min) with a flow rate of 24-44%. It is suitable for home use and allows patients to eat and talk easily.

Simple Oxygen Mask

The simple oxygen mask delivers 35% to 60% oxygen at a flow rate of 6 to 10 liters per minute. It is often used when an increased delivery of oxygen is needed for short periods, less than 12 hours.

Partial Rebreather Mask

A mask with a reservoir bag that must be inflated during inspiration and expiration. It collects the first parts of the patient's exhaled air, delivering oxygen concentrations up to 80% at a flow rate of 6 L/min or more.

Non Rebreather Mask

The highest concentration of oxygen (95 to 100%) is possible with this mask at a flow rate of 6-15 L/min. Similar to the partial rebreather mask but uses one-way valves to prevent exhaled air from being rebreathed.

Study Notes

Oxygen Therapy Overview

  • Oxygen therapy is the administration of oxygen at a concentration higher than ambient air (approximately 21% oxygen)
  • It's crucial for various conditions where the body's oxygen levels are too low.
  • Oxygen is a colorless, odorless, and tasteless gas essential for proper bodily functions and survival.

Learning Objectives

  • Define oxygen therapy and its purpose.
  • Identify different types of oxygen therapy.
  • Outline procedures for administering oxygen therapy.
  • Note potential complications of oxygen therapy.

Purposes of Oxygen Therapy

  • Increase oxygen saturation in tissues when levels are below normal, due to illness or injury.
  • Used to treat conditions like documented hypoxemia, severe respiratory distress (e.g., asthma, pneumonia), severe trauma, and chronic obstructive pulmonary disease (COPD), including chronic bronchitis, emphysema, and chronic asthma
  • Treat pulmonary hypertension and acute myocardial infarction (heart attack).
  • Often used as short-term therapy, such as post-anesthesia recovery.
  • Used for treating chronic lung disease patients during exercise.

Methods of Oxygen Administration

  • Low Flow Systems: These systems deliver oxygen that contributes partially to the inspired gas the patient breathes, the amount is dependent on the client's breathing. Examples include Nasal Cannula, Simple Masks, Partial Rebreathers, Non-rebreathers
  • High Flow Systems: These systems deliver specific and constant oxygen percentages,independent of the client's breathing. Examples include Venturi Masks, Trach Collar, T-piece.

Oxygen Delivery Devices

  • Nasal Cannula: A disposable plastic device with prongs inserted into the nostrils. Used for low to medium oxygen concentrations (24-44%).
  • Simple Oxygen Mask: A clear, flexible plastic or rubber mask molded to the face. Delivers 35-60% oxygen at 6-10 liters per minute. Suitable for short-term use.
  • Partial Rebreather Mask: Delivers oxygen concentrations up to 80% with a reservoir bag preventing the re-breathing of exhaled air. A minimum flow rate of 6 L/min is needed to maintain reservoir inflation.
  • Non-Rebreather Mask: Provides the highest oxygen concentrations (95-100%) at 6-15 Liters per minute. A reservoir bag is used, and one-way valves prevent re-breathing exhaled air.
  • Venturi Mask: Delivers specific and constant oxygen concentrations (40-50%) at 4-15 Liters per minute using a Venturi device. The specific oxygen concentration is determined by color-coded valves.
  • T-piece: Used during ventilator weaning, providing accurate oxygen delivery and humidity to the patient.

Cautions and Complications

  • Oxygen Toxicity: Can occur with inspired oxygen fractions (FIO2) greater than 50% for more than 48 hours.
  • Infection: A possible complication that needs to be considered.
  • Fire Hazard: Oxygen is a strong oxidizer.

Evaluation

  • Assess the patient's breathing pattern, color of nail beds, lips, conjunctiva.
  • Check for confusion, disorientation, cognition difficulties.
  • Evaluate arterial oxygen concentration/hemoglobin.
  • Monitor oxygen saturation with appropriate devices and methods.

Documentation

  • Record the timing of oxygen therapy initiation.
  • Document the method of delivery.
  • Note oxygen concentrations and flow rates.
  • Include patient observations.
  • Add oronasal care instructions to the patient plan for care.

Equipment Specifications

  • A table detailing oxygen delivery devices, flow rates, FIO2 (fraction of inspired oxygen), and special notes is included in a separate section for reference.
