Summary. Ventilator waveforms are graphical descriptions of how a breath is delivered to a patient. These include three scalars (flow versus time, volume versus time, and pressure versus time) and two loops (pressure-volume and flow-volume). Thorough understanding of both scalars and loops, and their characteristic appearances, is essential to

The basic variables that determine the appearance of ventilator waveforms include: Volume. Flow. Pressure. The volume of air delivered by the ventilator is influenced by the flow rate and the duration of the patient's inspiratory time. Flow, in turn, is governed by the pressure differential between the ventilator and the patient's lungs.

Ventilator waveform analysis is an integral component in the management of a mechanically ventilated patient. Develop a habit of looking at the right waveform for the given mode of patient ventilation. Always look at the inspiratory and expiratory components of the flow-time waveform.

Mechanical ventilators may incorporate software into the ventilator interface that allows a respiratory therapist (RT) to evaluate real-time patient-ventilator interactions. Graphics are displayed as different types of waveforms. The most common waveforms measure flow, pressure, and volume, and are graphed on a scale of time, called a scaler.

Ventilator waveforms are graphic representations of changes in pressure, flow, and volume within a ventilator circuit. The changes in these parameters over time may be displayed individually (scalars) or plotted one against another (pressure-volume and ow-volume loops).

An introduction to the ventilator waveform. The mechanical ventilator, secondary to its role as the deliverer of flows and the regulator of pressures, is also a complex measurement device for monitoring the behaviour of the respiratory system it has been connected to. It collects a vast amount of data from each breath and makes this knowledge

The Pre-brief. In Waveform Interpretation Part Two, we will discuss patient-ventilator dyssynchrony. Patient-ventilator synchrony is dependent on the ventilator responding to the patient's respiratory effort and demands and how the patient responds to the breath delivered by the ventilator.
