The AMBU bag and Its Use

An AMBU resuscitator bag sometimes called the generic or proprietary name a manual ventilator or “hand-in-hand resuscitator”, is an air-tight bag that delivers positive pressure air to a patient while he or she is not breathing on their own or not responding to other methods of ventilation.

An airtight seal with a wide mouth opening is designed to prevent the escape of inhaled air and to keep the chest area and abdomen of a ventilated patient completely sealed. Unlike a normal bag-valve-mask device, this design makes use of a venting system by means of an air compressor.

The venting system allows for more efficient delivery of pressurized air into the bag than can be obtained from an open-face mask. AMBU and other similar brands of this type of hand-held resuscitation bags are available in many hospital emergency departments (EDs) throughout the United States.

Highly Effective

These bags have been shown to be highly effective in many situations,۔ such as cardiopulmonary resuscitation (CPR) when an adult is unresponsive and not breathing on their own. They are also useful in other situations where additional oxygen is needed, such as those in the case of a baby or child with a severe respiratory condition. These bags are used in the line of duty nursing and other health care professions,۔ as well as in the home.

Many of these bags are made to be refilled with a preloaded syringe at the time of its purchase, making it convenient to use right out of the box. Refillable oxygen bags may also be purchased via the Internet or via direct mail in most cases.

Open-Mouth Bag

The bag valve, also known as an open-mouth bag valve,۔ is an important part of this type of hand-held resuscitation bag. This part of the device allows for a steady stream of oxygen to pass through the tube that connects the airway to the mask. It is designed to remain open while the rescuer attempts to open the mouth. Should the rescuer pull the tube shut before the airway can be opened, the bag will fail to perform its function.

Rescuing a patient who is not breathing on their own or with the assistance ۔of another person requires an accurate diagnosis and the proper medical response. Once an appropriate rescue attempt has been made. The next question is what happens to the victim’s oxygen intake after the rescuer has administered mouth-to-mouth resuscitation and airway rescue. The bag-valve-mask bag valve masks provide۔ a means for critically ill victims and severely injured victims to breathe in a steady stream of oxygen. Without interruption.

There are several types of this device.

The disposable type has an elongated shape that opens to allow admission of the victim’s expired lungs. While the regular type has a straight-sided, closed design. The face mask has two openings. One on the top, to accommodate the expired lungs, and a second opening on the bottom. For the easy admission of a continuous stream of oxygen. The face mask is generally clear. Plastic covering that overhangs the upper edge of the mouth. So that only a small amount of oxygen may enter the mouth.

In some circumstances, it is difficult for a victim to breathe when air cannot reach the lungs because of an obstruction in the airway or some other condition. Such obstruction may require the device to open even further. When air is breathed in, the bag opens to admit as much oxygen as possible into the lungs. Once it is opened, the valve shuts off and the supply of oxygen to the lungs ends. However, if the rescuer does not open the valve properly, the flow of oxygen can continue past the valve’s closure. Such an occurrence is referred to as “overflow.”
