In a respiratory arrest scenario for an 83-year-old female, how should you ventilate her?

Ventilating a patient in respiratory arrest requires ensuring effective breaths that can facilitate oxygenation. Squeezing the bag to cause visible chest rise at a rate of 10 breaths per minute is appropriate because this rate is generally effective for an adult patient. It allows for adequate time for the lungs to fill with air, which is crucial for oxygen exchange. The goal is to achieve effective positive pressure ventilation that results in visible chest rise, indicating that air is being appropriately delivered to the lungs.

The emphasis on visible chest rise is significant; it is a direct indication that the breaths are being delivered effectively. If the chest does not rise, it may suggest that either the airway is obstructed or the ventilation technique may need to be adjusted. Ventilating at a rate of 10 per minute also aligns well with airway management guidelines, which suggest that for adults, a rate of 10-12 breaths per minute is typically sufficient.

The focus on achieving an SpO2 between 94-99% and adjusting oxygen flow rates are also important considerations. However, they are more about the overall management of the patient’s oxygenation rather than the immediate action of providing ventilations. Additionally, the insertion of an oropharyngeal airway is a measure to
