What is a bag of bag valve?
The
Bag valve mask (BVM) is a device equipped with a face mask and a self -service section or a bag that a health care provider used to ensure artificial ventilation. This manual emergency medical device is designed to supply air directly from the atmosphere or pure oxygen from the additional system that supplies oxygen. The bag valve mask is sometimes called resuscitator or “Ambu® bag” and can be used not only in patients who are in respiratory arrests, but also on those suffering from respiratory failure. Respiratory arrests are a complete stop of spontaneous breathing; Respiratory failure concerns breathing that is not sufficient to continue to support life. This brand is produced in sizes for infants, children and adults. These parts include a self -service bag and a jam resistant that allows up to 15 liters of flow per minute, as well as nebreating. This feature is what prevents the patient from breathing the air that he exhales back. The device should not be ŽirrZnit even at temperatures below 32 ° F (0 ° C) and the bag should be easily cleaned and sterilized if the unit is not one -time. While the bag can come in more than one color, the mask is soft, clear plastic.
Other respiratory devices such as endotracheal or respiratory tubes can be used in conjunction with a bag valve mask, and therefore almost all units are equipped with a standard respiratory assembly 15/22. If additional oxygen is delivered to the patient during use, also known as bagging, is connected to the device and enters the tank. When the rescuer compresses the bag, the air entry closes and the oxygen from the tank is delivered to the patient. Passive exhalation occurs by the patient when Tzyná releases the bag. During the patient's exhalation, the air entry into the tank is open to allow oxygen to enter, so it can be delivered with the next bag.
It is possible to use a mask of a bag of bag with additional oxygen nEbo without him. The device can pull the air directly from the atmosphere when the oxygen is not connected. However, the use of additional oxygen is almost always a preferred possibility, especially in the case of airway arrest.
Getting a good seal over the mouth and nose of the patient is the most difficult part of using a bag of bag valve and bagging is not always successful if a single rescuer attempts to do so. For this reason, it is very strongly recommended that two rescuers work together so that one can maintain a good seal while other bags. The units of the bag valve mask are used not only to ensure artificial respiration, but also one of the most effective barriers of infection between the patient and the health care provider.
