What is an ambobe?
BVM was first invented in 1953 by a German engineer named Dr. Holger Hesse under the brand name Ambog.
Ambobag and its types
Ambobag is a silicone or plastic air tank that is used manually to create positive pulmonary pressure in pneumothorax conditions or in artificial respiration during CPR.
The volume of Ambobag tanks varies according to its efficiency and is made and marketed in volumes of 500,600, 1500 and 2000 cc.
<<> Ambobag is used in all medical centers and emergencies.
Ambobag has different parts. Its most important parts include the three main parts of the oxygen interface, storage bag and view valve, which are easily separated when washed and with a special material for 15 It is disinfected in minutes.
How to operate and use ambobag
Ambobag has a one-way valve that fills the airbag on its own and prevents it from emptying.
The ambobag must be transparent and connected to the oxygen interface, and the storage bag must also be connected to it, because the storage bag creates 90% pure oxygen inlet.
Ambobag has the ability to control the concentration of the patient’s tail air by attaching a mask to the oxygen tank or increase it to any amount.
The valve that is installed on the ambobag is with 20, 30 and 40 cm degrees of water, which should be when ventilating with a face mask, and when venting through the endotracheal tube, the valve should be open. Taken.
In this case, if the airway pressure is higher than the set temperature, for example 40 cm of water, the extra air pressure is not applied to the patient’s respiratory system and causes the air pressure to be controlled.
Applications of Ambobag:
When using an ambobag, oxygen must be connected to its inlet, and in order for the patient to receive the highest percentage of oxygen, the oxygen flow rate must be set at 10 liters.
The ampoule can be placed on the trachea using a mask on the respiratory tract, such as the nose and mouth, or using an adapter, and mechanically ventilated.
The effect of ambobag on mechanical ventilation can be seen by raising and lowering the chest. At different ages, the number of breaths with ambobags is different. In all age groups, having a tracheal tube is between 8 to 10 breaths, while when breathing with masks and ambogs, it is 12 to 20 breaths in infants and children and 10 to 12 breaths in adults. .
Under what conditions are ambobags used?
- Respiratory first aid before transporting a heart / respiratory injury patient to hospital
- Children with shortness of breath
- When endotracheal intubation is not possible or prohibited
- When intratracheal intubation is not required in small treatments or surgeries.
- Who has the problem of using ambobags?
- Dental patients (Because the structure of the mouth of patients who do not have teeth is slightly different from that of normal people, it is difficult to place an ambobag in patients who do not have teeth.)
- Patients who have a lot of hair on their face (It is difficult to put an ambobag in patients who have a lot of beard and sybil.)
- Obese or very thin patients (fitting a mask on the face of these people is difficult.)
- Patients with a history of severe snoring (these people may have difficulty breathing and have conditions that make it difficult to use the amputee.)
What tools are needed when setting up an ambobag?
Normally, the following tools should be available when using:
- Connection tube (attachment of the amulet to an oxygen source)
- Oxygen source (able to provide high concentration oxygen)
- Suction (discharge of stomach contents into the patient’s mouth and throat as a result of aspiration)
What should be the patient’s position when using the ampoule?
- Proper use is one of the most important skills that emergency personnel or nurses must master.
- NoteKeep in mind that with one hand the mask bag and with the other hand the mask should be used on the face as well as positioning the patient’s head.
- The patient’s head should be slightly above body level.
- Using a towel under the patient’s head to ensure open airflow can help the process work better.
- Make sure the patient’s head is positioned so that his ears are in line with the sternal cleft.
- If you suspect a neck injury or spinal cord injury, you should use chin movement to open the patient’s airway, otherwise use head movement to open the airway.
- If the patient does not have an abnormal reaction, you can use OPA (oropharyngeal airway) to have a free airway.
- If the patient can not tolerate OPA, use nasopharyngeal airway. (If there is a blow to the middle of the face, or important parts of the head, the nasal airway should never be used as this airway can enter the space inside the skull and be dangerous.)
