Parameters of spontaneous Ca²⁺ transients in pericytes of different microvascular segments measured with 95% N₂ + 5% CO₂

Segment	Amplitude (ΔF t /F 0)	Half‐width (s)	Frequency (min−1)
PCAs (n = 5)	2.28 ± 0.44 NS	13.2 ± 4.7 NS	1.54 ± 0.37 NS
Capillaries (n = 5)	1.99 ± 0.52 NS	12.9 ± 4.4 NS	1.74 ± 0.36 NS
PCVs (n = 6)	1.76 ± 0.28 NS	4.28 ± 0.85 NS	3.45 ± 0.21 NS
Venules (n = 5)	1.29 ± 0.28 NS	3.56 ± 0.61 NS	4.0 ± 1.26 NS

Data shown are the mean ± SD. NS, not significantly different from the values measured with 95% O₂ + 5% CO₂ (P < 0.05).
