Table 2.
Characterization of some cardiovascular episodes during asynchronies, by state. Percentage of 15-minute periods (%episode) with at least one episode of bradycardia, tachycardia, and/or hypoxemia, with respect to the total number of T = 15-minute periods; and mean (SD) percentage of time within each T = 15-minute periods (tepisode) with episodes of tachycardia, bradycardia, and/or hypoxemia.
| Episodes | Values for each state | |||
|---|---|---|---|---|
| z1 | z2 | z3 | z4 | |
| Bradycardia | ||||
| %episode | 8.36 | 7.74 | 4.55 | 9.07 |
| tepisode | 4.42 (18.8) | 2.43 (12.9) | 1.11 (8.58) | 1.86 (11.7) |
| Tachycardia | ||||
| %episode | 39.3 | 42.4 | 46.3 | 36 |
| tepisode | 25.5 (40.9) | 22.9 (38.3) | 28.2 (40.9) | 26.9 (42.6) |
| Hypoxemia | ||||
| %episode | 5.94 | 11.5 | 16.1 | 15.1 |
| tepisode | 1.95 (12.2) | 2.51 (12.6) | 3.66 (14.9) | 5.13 (19.4) |
Bradycardia episode = heart rate <60 bpm; Tachycardia episode = heart rate >100 bpm; Hypoxemia episode = oxygen saturation <90%.
