Basic Life Support (BLS) Practice Exam

Is it true or false that the preferred technique for BVM ventilation is for one provider to seal the mask while another depresses the bag?

1. True

2. False

3. Only in certain conditions

4. Depends on the patient's condition

The correct answer is: True

The statement is true because in a two-provider scenario, having one person dedicated to sealing the mask while the other squeezes the bag allows for more effective ventilation. This technique ensures that the mask is held securely against the patient's face to create a proper seal, which is critical for effective bag-valve-mask (BVM) ventilation. Proper sealing helps prevent air from escaping around the mask and ensures that the air being delivered goes into the lungs. This is particularly important in emergency situations where the patient's airway may be compromised. Having a second provider allows for better coordination and minimizes the risk of improper ventilation. In contrast, if one individual attempts to both hold the mask and squeeze the bag, it can be challenging to maintain an effective seal, which can lead to inadequate ventilation and poor patient outcomes. This technique exemplifies good teamwork in emergency care scenarios, enhancing the effectiveness of resuscitation efforts.
