Risk Pneumonia And Mischance Ventilation ( Ippv ) Is The Best Option For Patients With Impaired Conscious State

considered a relative contra- indication due to risk of aspiration pneumonia and mischance ventilation. According to international guidelines the conventional invasive mechanical ventilation (IPPV) is the best option for patients with impaired conscious state. 5 As IPPV is associated with many complications and difficulty in weaning in COPD patients . In this study NPPV in the form of BiPAP was given to COPD patients with type -2 respiratory failure and GCS between 10-15 and efficacy of BiPAP was monitored. The outcome of BiPAP in patients with normal GCS was compared to patients with low level of consciousness. 6 OBJECTIVE: To determine the effectiveness of BiPAP in COPD patients with Hypercap¬nic respiratory failure in relation to …show more content…

Also we adjusted the pressures during inspiration and expiration to maintain the saturation within required limits. If we increased the EPAP ,then the IPAP was also increased. EPAP can be increased up to 8 cm of H2O. BiPAP ventilation may be discontinued at time with clinical evidence of deteriorating conscious level or hemodynamic instability. Data Collection Demographic and baseline clinical data was collected from patients before being put on BiPAP. The information was obtained about age, gender, pH, GCS, PO2, PCO2, RR, Bicarbonate etc. The information about arterial blood gases was again taken from patients two hour after receiving ventilation with BiPAP The data was recorded in a structured Performa and then entered into SPSS 16. Arterial blood gases were compared before and after BiPAP ventilation in both Groups with reference to their Glasgow Coma Scale (GCS) . Mean and SD were calculated for quantitative vari¬ables. Paired `t’test and Chi-Square test were applied for comparison of relevant parameters. Results A total of 90 patients were included in this study. The mean (SD) age of study cohort was 63.7 (8.30) years with an age range of 40-80 years. The present study cohort has a male preponderance. On admission, out of total 90 patients,24 patients were in hypercapnic encephalopathy with GCS in between 10-14. & 66 patient were having GCS of
