RESISTANCE. The opposition of force to force.
     2. Resistance is either lawful or unlawful. 1. It is lawful to resist one who is in the act of committing a felony or other crime, or who maliciously endeavors to commit such felony or crime. See self defence. And a man may oppose force to force against one who endeavors to make an arrest, or to enter his house without lawful authority for the purpose; or, if in certain cases he abuse such authority, and do more than he was authorized to do; or if it turn out in the result he has no right to enter, then the party about to be imprisoned, or whose house is about to be illegally entered, may resist the illegal imprisonment or entry by self-defence, not using any dangerous weapons, and may escape, be rescued, or even break prison, and others may assist him in so doing. 5 Taunt. 765; 1 B. & Adol, 166; 1 East, P. C. 295; 5 East, 304; 1 Chit. Pr. 634. See Regular and Irregular Process.
     3.-2. Resistance is unlawful when the persons having a lawful authority to arrest, apprehend, or imprison, or otherwise to advance or execute the public justice of the country, either civil or criminal, and using the proper means for that purpose, are resisted in so doing; and if the party guilty of such resistance, or others assisting him, be killed in the struggle, such homicide is justifiable; while on the other hand, if the officer be killed, it will, at common law, be murder in those who resist. Fost. 270; 1 Hale, 457; 1 East, P. C. 305.

Pulmonary vascular resistance (Rpul) and lower-body arteriolar resistance ([R.sub.art_1]) are observed to have the most significant influence on the change in transpulmonary flow associated with the TCPC operation.
In addition, epoprostenol was associated with significant improvements of hemodynamic variables compared with conventional therapy alone, including mean pulmonary-artery pressure (P < .002 between treatments) and pulmonary vascular resistance (P < .001 between treatments).
Therefore, pulmonary vascular resistance is increased.
The filing is based on data from the randomized clinical trial, MERIT-1 which showed significant improvements in the primary and secondary endpoints of pulmonary vascular resistance and six-minute walk distance, respectively, for patients treated with macitentan compared with placebo.
The main hemodynamic determinants known to produce pulmonary hypertension in hyperthyroidism are increasing levels of thyroid hormones, pulmonary vascular resistance and high cardiac output.2-4 The excess of thyroid hormones leads to the increase of cardiac contractility, the increase of cardiac flow and of systolic pressure blood and decreases the systemic vascular resistance.2-4 The rise of CO is itself determined by the increase of HR and LVEF as an effect of the direct and indirect action of thyroid hormones and hyper-sympatheticotonia.
It is also found in published studies that ventilation with low tidal volume (3ml/kg) without PEEP per CPB could not significantly change pulmonary vascular resistance index (PVRI), mean pulmonary artery pressure (MPAP), pulmonary complications, PaO2/FiO2 ratio and total length of stay12-14.
Factors significantly associated a positive response to AVT in the CTEPH group were level of N-terminal pro-brain natriuretic peptide (≤1131.000 ng/L), mean pulmonary arterial pressure (mPAP, ≤44.500 mmHg), pulmonary vascular resistance (PVR, ≤846.500 dyn*s[sup]−1*m[sup]−5), cardiac output (CO, ≥3.475 L/min), and mixed venous oxygen partial pressure (PvO[sub]2, ≥35.150 mmHg).
General anesthesia had potential hazards of an acute rise in pulmonary vascular resistance and heart rate during laryngoscopy and intubation, negative inotropic effects of anesthetic drugs and the obstetrician's opinion of an easier vaginal delivery made us opt away from general anesthesia.
At birth, even with the first breath, pulmonary vascular resistance falls dramatically, and pulmonary blood flow increases rapidly.
