From the Guidelines
The oxygen delivery rate through a nasal catheter is 2-6 L/min. When a patient develops constricting chest pain during a procedure, the nurse should stop the procedure and call a doctor. For long-term oxygen therapy via nasal catheter, a break should be taken every 1-2 hours. Oxygen therapy with defoamers is indicated for pulmonary edema, and 96 degree of ethyl alcohol is used as a defoamer 1. Hemoptysis is a contraindication to inhalation therapy. For a general therapeutic bath, patients should be immersed in water up to the xiphoid process. Inhalation using a steam inhaler should be done 1-1.5 hours after eating. When using a pocket inhaler, the patient should cover the mouthpiece tightly with lips, take a deep breath while pressing the bottom of the inhaler. The nasal catheter position should be changed to the other nasal passage every 1-2 hours. An oxygen content of 30% in the oxygen-air mixture eliminates tissue hypoxia. If a patient develops nasal irritation during oxygen therapy, the nurse should temporarily stop oxygen administration and drip oil drops into the nose. When giving oxygen via mask, the error is pressing the mask tightly against the patient's mouth. If a patient's condition doesn't improve after multiple inhaler uses, the nurse should call the doctor. When using a pocket inhaler, the error is having the patient take a deep breath out while pressing the bottom. Oxygen cylinders maintain pressure at 150 atm. A pulse oximeter is the most common non-invasive way to measure oxygenation. For a patient with an asthma attack, the nurse should use a pocket inhaler with Salbutamol. Water in a thermal inhaler should be heated to 50°C. If a patient becomes pale with headache during a warm bath, the nurse should urgently stop the procedure and call a doctor. Some key points to consider:
- The BTS guideline for oxygen use in adults in healthcare and emergency settings recommends the use of nasal cannulae for medium-concentration oxygen therapy, with a flow rate of 2-6 L/min 1.
- The effectiveness and harms of high-flow nasal oxygen for acute respiratory failure have been studied, and the results suggest that high-flow nasal oxygen can be an effective treatment for acute respiratory failure 1. However, the question is about the oxygen delivery rate through a nasal catheter, and according to the BTS guideline, the recommended flow rate is 2-6 L/min 1. Therefore, the oxygen delivery rate through a nasal catheter is 2-6 L/min.
Some other key considerations:
- The patient's oxygenation status should be monitored closely, and the oxygen delivery rate should be adjusted as needed to maintain adequate oxygenation.
- The patient's comfort and safety should be prioritized, and the nurse should take steps to prevent complications such as nasal irritation or dryness.
- The nurse should be aware of the potential risks and benefits of oxygen therapy and take steps to minimize risks and maximize benefits. For example, the nurse should be aware of the risk of oxygen toxicity and take steps to prevent it, such as monitoring the patient's oxygenation status closely and adjusting the oxygen delivery rate as needed.
In terms of the patient's care, the nurse should:
- Monitor the patient's oxygenation status closely and adjust the oxygen delivery rate as needed to maintain adequate oxygenation.
- Take steps to prevent complications such as nasal irritation or dryness, such as dripping oil drops into the nose or using a humidifier.
- Prioritize the patient's comfort and safety, and take steps to minimize risks and maximize benefits.
- Be aware of the potential risks and benefits of oxygen therapy, and take steps to minimize risks and maximize benefits. For example, the nurse should be aware of the risk of oxygen toxicity and take steps to prevent it, such as monitoring the patient's oxygenation status closely and adjusting the oxygen delivery rate as needed.
Overall, the oxygen delivery rate through a nasal catheter is 2-6 L/min, and the nurse should prioritize the patient's comfort and safety, monitor the patient's oxygenation status closely, and take steps to prevent complications and minimize risks.
From the Research
Oxygen Delivery Rate
- The oxygen delivery rate through a nasal catheter is typically in the range of 1-6 liters per minute (L/min) [ 2 ].
- For a patient receiving humidified oxygen through a nasal catheter, a common oxygen delivery rate is 2-3 L/min or 4-6 L/min.
Nurse Actions During Constricting Pains
- If a patient develops constricting pains in the region of the heart, palpitations during a procedure, the nurse should stop the procedure [no direct evidence found].
Break Period for Nasal Catheter Oxygen Therapy
- There is no specific evidence found for the required break period when a patient is given humidified oxygen through a nasal catheter for a long period.
Indications for Oxygen Therapy with Defoamers
- Oxygen therapy combined with inhalation of defoamers is typically indicated for conditions such as respiratory failure, pulmonary edema [ 3 ].
Defoamer Used in Oxygen Therapy
- No specific evidence was found regarding the type of defoamer used in oxygen therapy.
Contraindications to Inhalation Therapy
- Contraindications to inhalation therapy include conditions such as hemoptysis, severe respiratory distress [no direct evidence found].
Immersion Level for General Therapeutic Bath
- The patient can be immersed in water up to the level of the xiphoid process or the umbilicus for a general therapeutic bath [no direct evidence found].
Timing of Inhalation Procedure
- The inhalation procedure using a steam inhaler can be carried out 1-1.5 hours after eating [no direct evidence found].
Actions When Using a Pocket Inhaler
- When using a pocket inhaler, the patient should cover the mouthpiece tightly with their lips, take a deep breath, and press the bottom of the inhaler [no direct evidence found].
Nurse Actions for Nasal Catheter Oxygen Therapy
- The nurse should change the position of the nasal catheter every 1-2 hours to prevent irritation and ensure effective oxygen delivery [no direct evidence found].
Oxygen Content to Eliminate Tissue Hypoxia
- The oxygen content in the oxygen-air mixture that eliminates the state of tissue hypoxia is typically around 30-50% [ 4 ].
Nurse Action for Nasal Irritation
- If the patient develops irritation in the nose and nasopharynx during oxygen therapy, the nurse should temporarily stop the oxygen introduction and consult a doctor [no direct evidence found].
Mistake in Nurse's Actions When Giving Oxygen Therapy
- A mistake in the nurse's actions when giving oxygen therapy using a mask is pressing the mask tightly against the patient's mouth [no direct evidence found].
Nurse's Actions During an Asthma Attack
- If a patient's condition does not improve after using a pocket inhaler during an asthma attack, the nurse should call a doctor [no direct evidence found].
