How Many Breaths Delivered Using Bag Mask Device?

The bag mask device provides effective respiratory support by delivering oxygen to the lungs through the mouth and nose. It is a vital tool for emergency medical professionals and first responders who may encounter patients in life-threatening situations, including cardiac arrest, drowning, drug overdose, or respiratory depression. Compared to traditional manual resuscitators, such as endotracheal intubation, the bag mask is more versatile and offers manual control of ventilation rate and volume. In addition, it is less invasive and requires minimal training to use.

When using a bag mask, the key to effectiveness is continuous observation and responsiveness. Observe the breathing rate of the victim to determine if it is adequate, and listen to lung sounds with a stethoscope to confirm that air enters the lungs during each ventilation. This allows the rescuer to ensure that they are not over-inflating or hyperventilating the patient, which can lead to complications, such as barotrauma.

Observing the breathing rate is particularly important in infants, as their respiratory rates are generally higher than those of adults. Ensure that the mask size is appropriate for the infant and that it is placed on the face with the correct hand position. The hand closest to the head should be placed on the forehead, and the index and middle fingers of the other hand should do a chin lift to facilitate a seal with the lips. The other hand should squeeze the bag, forcing air into the lungs during each ventilation. The rate of ventilation should be 12 breaths per minute for an adult, with each breath delivered over one second and a maximum volume of 10 liters.

If the victim is not breathing, or is unable to deliver breaths independently, a bag mask is typically used in conjunction with chest compressions. It is important to maintain a consistent rate of 30 compressions every 2 breaths for adults, and that the rate is coordinated with ventilation.

A bag mask is often used with supplemental oxygen to improve the level of oxygen in the blood, which can help improve the patient’s respiratory function. It can also be used for long periods of time, such as in cases of chronic respiratory disease like COPD or asthma, to provide ongoing respiratory support.

In some cases, a patient may need to be assisted with a bag mask before medical treatment can be administered, such as in remote locations where advanced medical care is unavailable. Despite its simplicity, it is a valuable tool in many emergencies, and a standard component of CPR and emergency response training.
