Pressure support ventilation (PSV), also known as pressure support, is a spontaneous mode of ventilation. The patient initiates every breath and the ventilator delivers support with the preset pressure value. With support from the ventilator, the patient also regulates their own respiratory rate and tidal volume. [1]
Anatomy and physiology is different in infants and children than adults and vary with age, which produces normal ranges for electrocardiograms. [26] Capillary refill is used across the lifespan as a cardiovascular assessment parameter because it is a non-invasive, quick test to help determine blood flow to the tissues.
PSV may refer to: Partial specific volume; Peak systolic velocity; Petit Saint Vincent, an island south of St. Vincent in the Grenadine islands; Platform supply ...
The lowest possible PGCS (the sum) is 3 (deep coma or death) whilst the highest is 15 (fully awake and aware person). The pediatric GCS is commonly used in emergency medical services. In patients who are intubated, unconscious, or preverbal, the motor response is considered the most important component of the scale.
Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch.

Vascular resistance is the resistance that must be overcome for blood to flow through the circulatory system.The resistance offered by the systemic circulation is known as the systemic vascular resistance or may sometimes be called by another term total peripheral resistance, while the resistance caused by the pulmonary circulation is known as the pulmonary vascular resistance.
An overall score above the cutoff point, sometimes referred to as a positive score, indicates need for further assessment. The cutoff score for children older than 6 years old is 28. [4] For children younger than 6 years old, four items that pertain to school are excluded. As a result, the range of scores is lower and the cutoff score is ...
A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). [2] It is determined by collecting data from vast numbers of laboratory tests.
