Neonatal respiratory machine five working regulation content

Breathing machine including pediatric breathing machine and adult respiratory machine, pediatric breathing machine and including neonatal respiratory machine and so on pediatric breathing medical equipment.

In the use of breathing machine, an emergency or estimate intubation retention time will not be too long, newborns, premature, general through the mouth intubation. Other situations can choose the nasal intubation or tracheotomy.

No matter what kind of breathing machine, work regulation content including tidal volume, suction call frequency, flow, suction call ratio, pressure, velocity.

A, tidal volume: moisture output must be greater than the physiological tidal volume, physiological tidal volume for 6 ~ 10 ml/kg, and breathing machine moisture output can reach 10 ~ 15 ml/kg, often is physiological tidal volume 1 ~ 2 times. Also according to the chest rises and fall, auscultation two lung inlet conditions, reference pressure two tables, blood gas analysis further adjustment.

Second, the suction call frequency: closer to the physiological respiratory frequency. Neonatal 40 ~ 50 times/points, the baby is 30 ~ 40 times/points, older son 20 ~ 30 times/points, adult 16 ~ 20 times/points. Tidal volume * respiratory frequency = minute ventilation

Three, suction call ratio: general 1:1. 5 ~ 2, obstructive ventilation disorder adjustable to one or more long exhalation time, restrictive ventilation disorder adjustable to 1:1.

Four, pressure: generally refers to the airway peak pressure (PIP), when pulmonary compliance with normal, suction pressure peak is generally 10 to 20 centimeters water column, lung lesions mild: 20 ~ 25 centimeters water column; Moderate: 25 ~ 30 mm water column; Severe: 30 centimeters water column above, RDS, pulmonary hemorrhage can reach 60 cm above the water. But in general under 30, for neonatal is the low pressure water 5 cm.
Five, velocity: need at least per minute ventilation two times, general 4 ~ 10 litres/minute.

Above is pediatric breathing machine, neonatal respiratory machine, adult respiratory machine work regulation content.
