Your assessmment of a newborn reveals cyanosis to the chest and face and a heart rate of 90 beats/min. What should you do first?
Burka [1]

Answer:

Begin artificial ventilations

Explanation:

Cyanosis is a very worrying symptom. It is a bluish tinge that appears on the skin or mucous membranes, most commonly on the fingertips and lips, which occurs when tissues do not receive adequate oxygen. The newborn, exposed in the question, has cyanosis, so we already know that he does not have the necessary amount of oxygen in his body. In addition, this newborn's heart rate is less than 100 beats / minute. This indicates that this child is required to receive artificial ventilation.

Artificial ventilation is an invasive life-support process that aims to optimize gas exchange and the patient's clinical status with minimal pressure, FiO2 and ventilation. This process aims to increase lung capacities, adjust gas exchange (reduce changes in the ventilation / perfusion ratio), reduce respiratory work (avoid muscle fatigue) and recruit atelectatic alveoli.
