What is NIPPV in neonates?
Nasal intermittent positive pressure ventilation (NIPPV) is a method of augmenting NCPAP by delivering ventilator breaths via the nasal prongs. Older children and adults with chronic respiratory failure have been shown to benefit from NIPPV and the technique has been applied to neonates.
When is CPAP indicated for an infant?
CPAP in infants is mainly used to treat respiratory distress syndrome (RDS). 2 RDS occurs when a baby is born prematurely before their lungs have fully developed. The lungs of these infants are deficient in surfactant, a slippery substance that enables smooth lung expansion and contraction.
Is Nasal high flow inferior to continuous positive airway pressure for neonates?
Rapid systematic review shows that using a high-flow nasal cannula is inferior to nasal continuous positive airway pressure as first-line support in preterm neonates. Acta Paediatr. 2018 Oct;107(10):1684-1696.
What is the only contraindication for assisting ventilations of an infant or child?
An oropharyngeal airway may be inserted in order to displace the tongue forward. This prevents the occlusion of the airway when the patient is laying supine. The only true contraindication to using it is if the patient has a gag reflex.
Why is CPAP use in neonates?
Continuous Positive Airway Pressure (CPAP) is a means of providing respiratory support to neonates with either upper airway obstruction or respiratory failure. Respiratory failure constitutes either failure of ventilation or failure of lung function.
Why do premature babies need CPAP?
The main goal of CPAP therapy is to keep the premature lungs properly inflated. While the air pressure is higher than a standard nasal cannula, CPAP is only used for babies who can breathe on their own. 3 Mechanical ventilation is used for premature babies who are too weak to breathe on their own.
What is the difference between CPAP and high flow nasal cannula?
HFNC delivers a heated, humidified airflow, and the FiO2 can be varied between 21% and 100% [8]. HFNC, like CPAP, is a high flow system and is able to generate a positive end expiratory pressure, but unlike CPAP it does not have a valve [9].
How does high flow nasal cannula work?
By creating a positive pressure environment, high-flow nasal cannula presses from the interior of the nasopharynx outwards. This dilates the radius of the nasopharyngeal airways and dramatically reduces the resistance to airway flow, thus increasing ventilation and oxygenation potential.
What is the main problem with positive pressure ventilation?
Among the potential adverse physiologic effects of positive-pressure ventilation are decreased cardiac output, unintended respiratory alkalosis, increased intracranial pressure, gastric distension, and impairment of hepatic and renal function.
