You are performing CPR on your uncle who collapsed at a family gathering where you are the only trained BLS provider. If possible, what is the preferred approach to deliver rescue breaths?

Explanation:

The American Heart Association recommends a rescue breath should be administered every 6 to 8 seconds and should last approximately 1 second. It emphasizes quality rather than quantity therefore, discourages too many rescue breaths.

The one-way valve  should be checked to confirmed if is well fitted.

Explanation:

The CPR mask is a safety device to aerate the victim blood, during oxygen shortage, it presented a physical barrier to prevent the mixing of the BLS saliva, and body-fluid with the patient own,

The   fitted one-way valve , is for giving the victim breath for resuscitation with the valve  to prevent  likely vomits, mucus, fluids or blood( from involuntary regurgitation )due to compression of the chest during CPR from  the mouth of the victim. Therefore this should be well checked to prevent possible suffocation.

the correct answer is yes the patient would be successful
