It aimed to resolve animal manure pollution problem and resourcalization, and to investigate the impacts on animal manure composting and transformation of nitrogen and phosphorus with two kinds of aeration control modes, time control and time-temperature control.

Objective To study the therapeutic effects of pressure controlled ventilation on post car-diotomy patients with cardiopulmonary bypass.

Objective To investigate the significance and effect of pressure controlled ventilation(PCV) as well as volume controlled ventilation(VCV) on respiratory mechanics and arterial blood gas analysis in aged patients underwent thoracic surgery.

Objective: To assess the effects on respiratory mechanics and oxygenation in treatment of patients with acute respiratory distress syndrome (ARDS) by pressure control ventilation (PCV) and volume control ventilation (VCV).

Method 40 obese patients undergoing gynecological laparoscopic surgery were randomly divided into pressure-controlled ventilation group (PCV) and volume-controlled ventilation group (VCV), 20 cases in each group.

In the present study, the effects of pressure-controlled ventilation (PCV) or volume-controlled ventilation (VCV) of peak inspiratory airway pressure (Ppeak), arterial oxygenation and intrapulmonary shunt(Qs/Qt) on obstructive ventilatory dysfunction patients, who undergoing elective right thoracotomy in the left lateral decubitus pos

ObjectiveTo compare the effects of pressure-controlled ventilation (PCV) with volume controlled ventilation (VCV) on peak airway pressure (Ppeak),arterial oxygenation and intrapulmonary shunt(Qs/Qt) in patients with obstructive ventilatory disorder during one-lung ventilation (OLV).
