Table 1 Indices of breathing pattern in anesthetized tracheostomized rats in supine and HDT positions during breathing at rest.

From: Effects of body position on the ventilatory response to hypercapnia

Indices Supine HDT
PETCO2 (mmHg) 32.8 ± 3.1 33.0 ± 2.8
VT (ml) 0.9 ± 0.1 0.9 ± 0.1
f (min-1) 100 ± 10 108 ± 19
VE (ml · min-1) 91.1 ± 8.4 93.1 ± 10.8
PesI (mmH2O) 22.5 ± 2.9 34.6 ± 5.2*
  1. PETCO2 - end-tidal fraction of CO2; VT - tidal volume; f - inspiratory rate; VE - minute ventilation; PesI - peak esophageal pressure; Values are means ± SE. *Significant difference from the supine position; P < 0.05.
