Table 3.

Values for broilers pooled by gender regardless of age, including their body weights, heart ventricle weights, right to total ventricular weight ratios (RV:TV ratio), and blood pressures recorded as a catheter was advanced through the vasculature (Venous 1, R. Atrium 1, R. Ventricle 1, and Pulmonary Artery 1 pressures) until the wedge pressure was obtained, and as the catheter was withdrawn from the vasculature (Pulmonary Artery 2, R. Ventricle 2, R. Atrium 2, and Venous 2 pressures)¹

^a,b

Superscripts designate differences (P ≤ 0.05) between genders within a variable.

^w–z

Superscripts designate differences (P ≤ 0.05) between blood pressures regardless of gender.

Data are presented as mean ± SEM. The trans-pulmonary gradient equals the pulmonary artery pressure minus the wedge pressure.
