Observation | Issues to be observed |
---|
Does the chest rise? | Does the mask sit tightly on the face? |
Is the mask of the right size? |
Are the head position and the grip correct? |
Is the oral airway of the right size? | The oral airway must be measured before insertion. The correct length is the distance from the corner of the patient's mouth to the earlobe. |
If the oral airway is of the wrong size, it will obstruct rather than open the airway. |
Is air going into the stomach? | Make sure that the airway is patent. |
Sufficiently long inspiration (approx. 1 s) synchronized with compression (in the case of cardiac arrest) |
Is the airway device (supraglottic or endotracheal tube) in the correct position? | Correct positioning must be ensured immediately after insertion primarily based on the expiratory carbon dioxide flow curve. |
Auscultate breath sounds. |
