Process

The Nurse is aware of the possible adverse effects, anticipates and prevents problems, recognises early signs of adverse effects and initiates intervention.

Step	Action
1	Hyperinflation may result and manifest by decreased cardiac output recognised by: tachycardia; decreased peripheral pulse; peripheral shutdown; decreased blood pressure and desaturation.
2	Pneumothorax signs may be gradual occurring over several hours. Indications are deterioration of blood gas and saturation levels and decreased vibrations on affective side.
3	Increased risk of dislodgment of ET tube due to the short rigid vibrating tubing.
4	The association between HFOV and IVH remains open. Studies report varying IVH rates of this multifactorial complication.
5	Airway damage In line suction is always to be used for infants on HFOV.
