Abstract
Background: Pneumonia is still considered a serious medical disorder linked to significant rise in morbidity and mortality with cost load.The aim: The study purpose to compare the effect of flow and volume-oriented spirometry on patients with pneumonia. Methods: Forty male patients with pneumonia recruited from El-Kateb Hospital participated in the study.Their age ranged from 50 to 60 years.The patients were assigned randomly into two groups equal in number.The first group (A) included 20 patients who used flow-oriented spirometry with breathing control exercise with 3-4 times daily for one week. The second group (B) included 20 patients who used volume-oriented spirometry with 3-4 times breathing control exercise per day for one week. PaO2 and PaCO2 were examined by arterial blood sample analysis through the Laboratory GEM premier 3000 device.The oxygen saturation (SpO2) was measured using a pulse oximeter.All the measurement was done for every patient pre and post study in both groups.The results: Within groups (A and B), the results proved a significant increase in PaO2 (P=0.002 and 0.001 respectively), SpO2 (P=0.002 and 0.001 respectively) with no significant change in PaCO2 (P=0. 4 and 0.7 respectively). In between groups, PaO2 and SpO2 revealed significant differences (P=0.03 and 0.04 respectively) (p<0.05). However, the latter showed more improvement in both variables (27.1% and 6.6% respectively) compared to (14.2% and 3.1% respectively) in the former group
