A method of augmented spontaneous ventilation that is flow, pressure or time cycled pressure limited and patient triggered. A form of spontaneous ventilation where flow is delivered to the airway up to a clinician pre- set pressure limit and continued until the machine senses either a drop in inspiratory flow beyond a preset threshold, excessive inspiratory pressure or prolonged inspiratory time. In PSV the patient determines the inspiratory rate, time, volume and flow. PSV can be employed as a mode of mechanical ventilation or in the SIMV mode.

Lesions caused by unrelieved pressure that results in damage to underlying tissue (e.g., decubitus ulcers, pressure sores, or bedsores).
Pulmonary Interstitial Emphysema
A term sometimes used to refer to the distal portion of multiple lumens that branch out from a single vascular access catheter (ex. pulmonary artery monitoring catheter).
Secondary intermittent infusions delivered through a port on primary infusion set.
This relates to kinking and/or fragmentation of a central venous catheter by chronic compression from adjacent anatomical structures.
The yellowish-straw-colored fluid, portion of the circulatory system in which the blood cells circulate. Contains clotting factors. If the plasma is clotted the residual non-clotted fluid is the serum.
B cell (B lymphocyte) may differentiate into an antibody producing factory that produces specific antibodies to specific microorganisms with which it comes in contact.
The most frequently used method of measuring a bacterial population on a nutritious (blood or broth infused) solidified agar that allows you to spread the sample out, incubate the plate, and count the subsequent colonies. One discrete colony represents the progeny from one distinct bacteria that was present in the patient sample or other source.
Measurement of the volume change of an organ. e.g. the lungs.
