Figure 4.

Comparison of the HR and SpO₂ values between groups during the observed period. During the observed period the HR is significantly different (p<0.01) with a significant linear trend of depreciation of the HR (p<0.01) but there was no significant difference in the fluctuations of the values at different points of measurement (p=0.917). Changes in HR do not vary significantly over time for both group (p=0.456). SpO₂ values do not differ significantly between the groups (p=0.081) or in the observed period (p=0.475).
