Vital signs measurements and comparison before and after imaging in normal and disease groups
| Normal Group (18 Subjects) | Disease Group (65 Subjects) | Intergroup | |||||
|---|---|---|---|---|---|---|---|
| Before | After | Difference | Before | After | Difference | P value | |
| Respiratory rate (rpm) | 14.3 | 14.8 | 0.5 ± 0.39 | 14.5 | 15.1 | 0.56 ± 0.18* | .86 |
| Temperature (°F) | 97.1 | 97.2 | −0.11 ± −0.24 | 97.3 | 97.2 | −0.06 ± 0.06 | .746 |
| Heart rate (bpm) | 65.2 | 60.3 | −4.83 ± 1.16† | 70.6 | 70.3 | −0.32 ± 0.79 | .006 |
| SBP (mm Hg) | 120.9 | 124.2 | 3.27 ± 2.78 | 130.3 | 132.2 | 189 ± 1.25 | .621 |
| DBP (mm Hg) | 74.5 | 78 | 3.5 ± 1.46 | 79.5 | 91.1 | 1.62 ± 1.03 | .376 |
| Oxygenation (%) | 97.2 | 97.4 | 0.21 ± 0.82 | 96.8 | 96.7 | −0.09 ± 0.32 | .685 |
| MAP (mm Hg) | 90 | 93.4 | 3.42 ± 1.63 | 96.4 | 98.1 | 1.71 ± 0.96 | .372 |
Note:—SBP indicates systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial blood pressure. Intergroup comparison was performed by Student t-text.
* Respiratory rate change in disease group before and after imaging is significant by paired t test (P < .001).
† Heart rate change in normal group before and after imaging is significant by paired t test (< .001).
