Oxygen Non Rebreather Bag Safety Vent O2 Reservoir Bag

A non-rebreather bag, also known as a non-rebreather mask, is a medical device used for the delivery of high-concentration oxygen to a patient. It is designed to deliver oxygen to the patient while preventing the re-inhalation of exhaled gases.

The non-rebreather bag consists of the following components:

Mask: The mask covers the nose and mouth of the patient, ensuring a secure fit. It is usually made of transparent material and has an adjustable strap to keep it in place.

Reservoir Bag: The reservoir bag is a soft, expandable bag attached to the mask. It is capable of holding a significant volume of oxygen, allowing the patient to draw from the bag during inhalation.

One-Way Valves: The non-rebreather bag has one-way valves built into it. These valves allow the flow of oxygen into the mask during inhalation while preventing the patient from inhaling exhaled air or ambient air.

Oxygen Supply Tubing: The non-rebreather bag is connected to an oxygen source through tubing. The oxygen supply tubing delivers a high flow of oxygen from the source to the reservoir bag.

The non-rebreather bag operates on the principle of delivering oxygen at a higher concentration than ambient air. During inhalation, the patient breathes in pure oxygen from the reservoir bag, while exhaled gases are expelled through the one-way valves and vent holes in the mask. This helps to minimize the risk of re-inhaling exhaled gases.

The non-rebreather bag is commonly used in emergency situations, such as in hospitals, ambulances, or during resuscitation efforts. It provides a high concentration of oxygen to patients who require immediate and significant oxygen supplementation.

What is a Non Rebreather Bag?

A non-rebreather mask is a face mask that covers both the nose and mouth. It has two one-way valves:

• One valve is between the face mask and a plastic reservoir bag (typically 1 liter) that’s attached to a supply of oxygen. The valve doesn’t allow exhaled air or outside air from entering the bag, so only oxygen flows from the bag to the mask.
• The other valve allows exhaled air to flow into the atmosphere but doesn’t allow the outside air to enter.

This mask is called “non-rebreather” because, when you’re using it, you’re unable to inhale anything you exhale. It allows you to breathe only pure oxygen. A non-rebreather mask typically delivers 70 to 100 percent oxygen.

Most non-rebreather masks don’t form a perfect seal on your face, in which case you’ll also breathe in some of the air around you.

The non-rebreather bag is typically used in medical settings, such as hospitals, emergency departments, and ambulances, for patients who require high-concentration oxygen therapy. Here are the general steps for using a non-rebreather bag:

• Prepare the equipment: Ensure that you have a properly functioning non-rebreather bag, oxygen source, oxygen tubing, and a mask of appropriate size for the patient.
• Position the patient: Place the patient in a comfortable position, typically sitting upright or semi-reclined, to facilitate breathing.
• Connect the oxygen source: Connect one end of the oxygen tubing to the oxygen source, such as a flowmeter or oxygen cylinder. Make sure the oxygen flow rate is set as prescribed by the healthcare provider.
• Assemble the non-rebreather bag: Attach the other end of the oxygen tubing to the inlet port on the non-rebreather bag. Ensure a secure connection.
• Adjust the mask: Place the mask over the patient's nose and mouth, ensuring a snug fit. Adjust the strap on the mask to secure it in place.
• Open the oxygen flow: Turn on the oxygen flow at the prescribed flow rate. The oxygen will fill the reservoir bag attached to the mask.
• Monitor the patient: Observe the patient closely for signs of proper oxygen delivery, such as rising and falling of the reservoir bag during inhalation and exhalation. Monitor the patient's vital signs and oxygen saturation levels if possible.
• Administer oxygen therapy: Instruct the patient to breathe normally through the mask. The non-rebreather bag will deliver high-concentration oxygen during inhalation, while exhaled gases will exit through the one-way valves and vent holes in the mask.
• Continuously assess the patient: Regularly assess the patient's response to the oxygen therapy, including their breathing pattern, oxygen saturation levels, and overall clinical condition.

It is important to follow the instructions and recommendations provided by healthcare professionals when using a non-rebreather bag. They can guide you on the appropriate oxygen flow rates and monitor the patient's response to ensure effective and safe oxygen therapy.

1. The star lumen tubing can ensure oxygen flow even if the tube is kinked, different length of the tubing is available.
2. Low-resistance check valve does not contain natural rubber latex, prevents rebreathing and allows exhaled gas to escape.
3. Clear, soft PVC for patient comfort and visual assessment.
4. Adaptor swivels to accommodate patient position
5. Safety vent allows for entrainment of room air.
6. Adjustable nose clip assures comfortable fit.
