Volume controlled ventilation (VCV) and pressure controlled ventilation (PCV) are the basic modes of controlled mechanical ventilation used during general anesthesia. Pressure support and pressure control with volume guarantee (PV-VG) are also available on newer anesthesia machines.

BACKGROUND: Anesthesia workstations with pressure support ventilation (PSV) are available, but there are few studies published on how to program flow-triggered PSV using a laryngeal mask airway (LMA) under general anesthesia in pediatric patients.

I read with interest the study by Jaber et al. 1 and the accompanying editorial by Tantawy and Ehrenwerth2 regarding pressure-support ventilation (PSV). The Jaber study is noteworthy for documenting that the performance of PSV using modern anesthesia ventilators approaches the performance of an intensive care unit ventilator.Cited by: 2

Pressure support mode may be useful during general anesthesia with spontaneous ventilation because it can reduce the patient’s work of breathing and increase tidal volumes. 1 During pressure support ventilation, a pressure support breath is triggered when changes in flow or pressure within the breathing circuit exceed the programmed trigger value. . The Drager Apollo anesthesia machine uses ...

INTUBATION and mechanical ventilation cause a redistribution of ventilation:1,2 compared with spontaneous breathing (SB) in the awake state in supine position, positive-pressure ventilation (PPV) increases the aereation in the ventral parts of the lung, whereas the dorsal parts contain less air. General anesthesia with a laryngeal mask airway allows safe and sufficient patient ventilation with ...Cited by: 63

BACKGROUND: Gastric insufflation frequently occurs during facemask ventilation in children. In the present study, we compared the incidence of gastric insufflation between pressure-controlled facemask ventilation and manual facemask ventilation during general anesthesia induction in children.

Pressure support ventilation (PSV) weaning had a better respiratory outcome. A higher V T, V T /body weight, PaO 2 /FiO 2 ratio and a lower f R /V T ratio and P e ′CO 2 were accurate in predicting the effect of weaning in healthy horses recovering from general anesthesia.Cited by: 4

PSV is a pressure-targeted (or limited) mode in which each breath is patient-triggered and supported. 10–13 It provides breath-by-breath support by means of a positive-pressure boost synchronized with inspiratory effort: patient initiated and flow terminated ().During inspiration, airway pressure is raised to the preset pressure-support level.
