What is the oxygen concentration range for a resuscitation mask?

For a resuscitation mask, the oxygen concentration range is typically around 35-55%. This percentage indicates the amount of oxygen delivered to the patient during bag-mask ventilation, which is crucial in situations where effective respiration needs to be restored. The range reflects the effectiveness of the mask in creating a seal over the patient’s face, allowing for an adequate supply of oxygen while minimizing the loss to the surrounding environment.

When using a mask, the concentration of oxygen can vary based on factors such as the airway management technique, the fit of the mask, and the flow rate of oxygen being administered. This range provides a practical guideline for responders to ensure that the administered oxygen is sufficient for effective resuscitation efforts.

In contrast, other options either understate or overstate the concentration levels that a resuscitation mask can provide, which can lead to misunderstandings regarding the effectiveness of the equipment in delivering oxygen to the patient in need of assistance.
