Data analysis is the systematic organization and synthesis of research data and testing of research hypothesis using those data. Interpretation is the process of making sense of the result and examining their implication (Polit, 2004). Analysis is the method of rendering qualitative data meaningful and providing intelligible information, so that the research problem can be studied and tested, including the relationship between the variables.
The study was conducted among children with wheezing to compare the effectiveness of nebulization with oxygen and without oxygen in improving their respiratory status. The data was collected, assembled, analyzed and tested and the findings based on the analysis are presented in this chapter.

Out of this, 8 (16%) children were between the age group of one month to one year, 17 (34%) were between 1-3 years and 25 (50%) were between the age group of 3-5 years. Majority of the children were males (62%) and female children were 38%. 34 (68%) children belonged to nuclear family whereas 16 (32%) children belonged to joint family. LPG was used as the cooking fuel in all (100%) the houses (Table 4.1).
4.2 Family History of Smoking Habits: In nebulization with oxygen group, 5(20%) children had the family history of smoking habit. For majority (4) of children, grandfather was the person who smokes and for one child father was the smoking person. In nebulization without oxygen group, fathers of 3(12%) children smoke in the family (Table 4.2).
4.3 Family History of Respiratory Diseases: 5 (20%) children in the nebulization with oxygen group had a family history of asthma, out of which one person is on regular treatment. In nebulization without oxygen group, 5(20%) children had a family history of asthma and 3(12%) had a family history of COPD, out of which one person is on regular treatment (Table4.3).

Therefore, it can be inferred that the mean difference was high in nebulization with oxygen group comparing to nebulization without oxygen group. This showed that nebulization with oxygen is effective in reducing tachypnea among children with wheezing (Table 4.7).
4.11.2 Mean Difference of Oxygen Saturation in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Oxygen saturation above 98% in room air is considered as the normal saturation level.

4.14. Comparison of Respiratory Parameters Between Nebulization with Oxygen Group and Nebulization without Oxygen Group through ‘Z ‘Test Analysis: ‘Z ‘test was used to assess the difference in respiratory parameters between nebulization with oxygen and nebulization without oxygen group.
4.14.1 Comparison of Respiratory Rate after 5 Minutes of Nebulization in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Hypothesis: There will be a significant difference in respiratory rate between nebulization with oxygen group and nebulization without oxygen group.
= 40.4
= 36
SD = 8.63
Z =1.81
Using ‘Z’ test, the calculated value of ‘Z’ is 1.81 which is less than the tabulated value at p <0.05 level. This shows that there is no significant difference in respiratory rate after 5 minutes of nebulization in nebulization with oxygen group and nebulization without oxygen group. (Table 4.10)
4.14.2 Comparison of Oxygen Saturation after 5 Minutes of Nebulization in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Hypothesis: There will be a significant difference in oxygen saturation between nebulization with oxygen group and nebulization without oxygen group.
= 96
= 95.88
SD= 1.59
Z=0.27
Using ‘Z’ test, the calculated value of ‘Z’ is 0.27 which is less than the tabulated value at p <0.05 level. This shows that there is no significant difference in oxygen saturation after 5 minutes of nebulization in nebulization with oxygen group and nebulization without oxygen group. (Table 4.10)
4.14.3 Comparison of Wheeze Score after 5 Minutes of Nebulization in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Hypothesis: There will be a significant difference in wheeze score between nebulization with oxygen group and nebulization without oxygen group.
= 1.4
= 1.12
SD= 0.55
Z=1.87
Using ‘Z’ test, the calculated value of ‘Z’ is 1.87 which is less than the tabulated value at p <0.05 level. This shows that there is no significant difference in wheeze score after 5 minutes of nebulization in nebulization with oxygen group and nebulization without oxygen group. (Table 4.10)
4.14.4 Comparison of Retraction Score after 5 Minutes of Nebulization in Nebulization with Oxygen Group and Nebulization without Oxygen Group: Hypothesis: There will be a significant difference in retraction score between nebulization with oxygen group and nebulization without oxygen g
