Simple oxygen mask Indication of oxygen therapy - room air o2 saturation less than 94 percent
provides 35—60% Fio2 at oxygen flow of 6—10 liters/ min. With each liter increase in oxygen, FiO2 increases by nearly 10%. Flow less than 5 liters / min should not be used as it can cause carbon dioxide retention and rebreathing of retained C02.
Non rebreathing mask provides an Fi02 of 80—100%at oxygen flow rate of 8—15L/min.
Nasogastric tube Indications 1.Feeding sick and premature infants 2.Feeding an unconscious child 3.For gastric decompression in cases of intestinal obstruction, paralytic ileus 4.To administer medications 5.Gastric lavage in cases of poisoning
When to begin l.Baby is apneic or gasping 2.Heart rate is below 100 /min Rate 1.40—60 per minute, when given alone When to stop l.Baby is having spontaneous respiration 2.Heart rate is more than lOO/min
