Arterial blood gas (ABG) samples were obtained from each patient before starting and then 2 hours and 24 hours after BiPAP therapy.
Responders to the treatment were defined as patients who gained full consciousness after BiPAP therapy.
Patients were extubated once they gained full consciousness and thereafter were given BiPAP through facemask.
The results of ANCOVA indicating a significant effect of therapy with BiPAP applied through endotracheal tube, when calculated for pH, PaCO2 and GCS is shown in Table-II.
Reduced dyspnea, decreased respiratory rate, decreased use of accessory muscles, improved blood gas values, and synchronization with the BiPAP ventilator would indicate effective ventilation.
Although several devices are available for NPPV (including volume targeted ventilators), the majority of published research regarding pediatrics describe experiences with the BiPAP system (Teague & Fortenberry, 1995).
Since BiPAP is usually used nocturnally, the functions of speaking and eating are preserved (Padman, Nadkarni, et al.
Padman, Lawless, and colleagues (1994) and Padman, Nadkarni, and associates (1994) have shown successful use of BiPAP outside of the hospital intensive care unit.
