Final answer:
The third step in giving ventilations for infants involves giving gentle breaths with proper technique and, in a medical setting, potentially using advanced equipment like a bag valve mask. Medical treatments for infant respiratory issues may include mechanical ventilation, administering pulmonary surfactant, and supportive therapies.
Step-by-step explanation:
The third step of giving ventilations for infants, particularly in the context of resuscitation and support for conditions like Respiratory Distress Syndrome (RDS), may involve other advanced medical interventions depending on the situation. However, the basic step during CPR, after ensuring that the airway is open through positioning, is to actually give gentle breaths to the infant. Since this is highly sensitive and the lungs of infants are delicate, these breaths should be provided with care and should not be too forceful to avoid injury. A healthcare professional would utilize the appropriate equipment such as a bag valve mask to assist with the breathing process, ensuring that the ventilations are gentle and at the correct rate.
Medical advances have significantly reduced mortality from RDS by 50 percent, notably through the introduction of pulmonary surfactant therapy. Treatment may also include nasal continuous positive airway pressure (CPAP) or mechanical ventilation, along with other supportive therapies for temperature regulation, nutritional support, and possible antibiotic treatment.
It is important to note that the specific instructions for the third step of giving ventilations to an infant can vary, and performing such medical procedures should be done by trained health professionals or under strict guidance following an established protocol, such as the American Heart Association guidelines for CPR and emergency cardiovascular care.
