How many times do you breathe during mouth-to-mouth resuscitation?

• A. 10-12 times a minute
• B. 4-6 times a minute
• C. 8-10 times a minute
• D. 12-15 times a minute

Answer: (B)

During mouth-to-mouth resuscitation, the recommended rate of breaths is indeed 4-6 times a minute. This allows sufficient time for the chest to rise and fall while also ensuring the person receiving rescue breaths is not overwhelmed or hyperventilated. The focus is on providing a controlled and steady breath at a rate that supports effective ventilation while also allowing time between breaths for the lungs to refill with air and the blood to adequately absorb the oxygen.

Breathing at a rate higher than this can lead to complications such as increased intrathoracic pressure, which hampers circulation and can result in reduced effectiveness of the resuscitation efforts. Hence, 4-6 breaths per minute strikes a balance between providing necessary oxygen and maintaining the overall physiology of the resuscitation process.
