Mean volume of liquid or air in the bulbs of Foley catheters on days 0, 3, 5, and 10
| Foley bulb volume (mL ± s)

||||
|---|---|---|---|---|
| Medium | Day 0 | Day 3 | Day 5 | Day 10 |
| Air | 5 ± 0 | 0 ± 0 | 0 ± 0 | 0 ± 0 |
| Sterile water | 5 ± 0 | 3.20a ± 1.788 | 2.84a ± 1.589 | 2.24a ± 1.252 |
| Saline | 5 ± 0 | 3.16a ± 1.768 | 3.8 ± 0 | 1.07b ± 7.505 |
s — standard deviation.
a
Ruptured bulbs were included in the calculation as 0 with the exception of the saline group at day 10.
b
This mean was calculated using 3 Foley catheters because 2 ruptured at day 0. However 2 of the remaining 3 bulbs that were found to be ruptured at day 10 were included in the calculation as 0 when calculating the mean.
