What to Do If Hypoxia Occurs During Suctioning?

Hypoxia during suctioning is one of the most common issues that can affect a patient's health and safety. The good news? It's preventable with proper techniques and the right equipment. This article will help you understand why hypoxia happens, whether oxygen support is needed, and how to perform suctioning correctly.  

Why Does Hypoxia Happen During Suctioning?

Several factors can cause hypoxia during suctioning. Let's break it down:  

1. Worsening Airway Obstruction  

If secretions aren't removed effectively and get pushed deeper into the airway, it can make the blockage worse. Similarly, inserting the suction catheter too deep can trigger spasms in the airway, narrowing or even blocking it entirely.  

2. Excessive Suction Pressure  

Using too much suction power can collapse the airway, especially in fragile patients like newborns or the elderly. High suction pressure can also damage airway tissues, causing inflammation or bleeding, which worsens oxygen flow. 

3. Interrupted Oxygen Supply  

For patients relying on oxygen therapy, even a brief pause in oxygen supply during suctioning can cause their oxygen levels to drop quickly. This is especially dangerous for patients with chronic respiratory issues or those on ventilators. 

4. Prolonged Suction Time  

Suctioning temporarily halts normal breathing, so if it takes too long (more than 10–15 seconds), oxygen levels can drop. Anxiety or struggling during the process can make it even worse.  

5. Inappropriate Equipment  

Using the wrong suction catheter—too stiff or the wrong size—can irritate or damage the airway. A catheter that's too large might block airflow, while one that's too small may not effectively remove secretions.

Do You Need Oxygen Support During Suctioning?  

• For Most Patients : If the oxygen saturation (SpO2) is within the normal range (94–98%), additional oxygen may not be needed.  
• For High-Risk Patients: Elderly patients, critically ill individuals, or those with respiratory conditions (like COPD or asthma) should receive oxygen support during suctioning.  
• For Special Cases :Post-surgery patients, those intubated, or ventilator-dependent individuals require extra care to maintain oxygen supply during suctioning. 
  
  

How to Perform Suctioning Correctly  

Before You Start  

1. Assess the Patient: Check their medical history, oxygen levels, and breathing rate.  

2. Prepare the Equipment: Use a soft suction catheter, adjustable suction machine, and have oxygen equipment ready.  
 

Step-by-Step Process  

1. Wash Your Hands: Prevent infection with proper hand hygiene.  

2. Set Up the Equipment: Connect the suction catheter to the machine and adjust suction pressure to a safe range (80–120 mmHg).  

3. Suctioning

1. Gently insert the catheter no deeper than 15 cm.  

2. Rotate the catheter slightly while suctioning to clear secretions.  

3. Limit suctioning to 10–15 seconds.  

4. Take Breaks: Pause between suctioning to let the patient rest and provide oxygen support.  
 

After the Procedure  

1. Monitor the Patient: Check oxygen levels, breathing, and overall condition.  

2. Clean the Equipment: Disinfect the catheter and suction device to prevent cross-contamination.  

How to Choose the Right Equipment  

Soft Suction Catheters

These are gentler on the airway and ideal for elderly, pediatric, or sensitive patients. Bever Medical's soft suction catheters are made with high-quality materials, offering flexibility and comfort to protect the airway.  

Adjustable Suction Devices

A device with adjustable suction levels ensures you can meet different patients' needs.  

Oxygen Equipment

Keep portable oxygen tanks or fixed oxygen systems on hand for immediate use.  

Disposable Supplies

Use single-use catheters to reduce infection risks.

FAQs  

Q: What if the patient coughs more after suctioning?  

A: Coughing is a natural response to airway irritation. Try reducing suction pressure or offering oxygen to ease discomfort.  

Q: How do I know if suctioning was successful?  

A: Signs of success include less secretion, smoother breathing, and normalized oxygen levels.  

Q: How often should suctioning be done?  

A: It depends on the patient's secretion levels. In most cases, every 2–4 hours is sufficient. 

Final Thoughts  

Hypoxia is a common challenge during suctioning, but it's manageable with the right approach and equipment. Bever Medical offers soft suction catheters that can improve care quality, offering flexibility and comfort for the elderly, children, and high-risk patients. Ready to learn more or place an order?
