Medical Apparatus Isoflurane Anesthesia Ventilator Machine

Feature:
Integrated breathing circuit with APL valve, excellent tightness.
Replacing drive bellow is NOT required when operating adult/pediatric anesthesia.
Real-time detection for loops, Paw, BPM, VT and compliance.
Comprehensive monitoring capabilities include ventilation parameters monitoring, preset parameters, alarm indication and breathing waveform monitoring.
Equipped with head light.
Altitude compensation function.
ACGO available to connect with T/Bain circuit for open operation.
Yoke system with up to 3 back up cylinders (A type with 11L size) (Optional).

Specification:
Pressure-volume loops in the presence of lung pathology
Pressure-volume loops can inform us about changes in the patient's lung compliance, air leaks, patient-ventilator dyssynchrony, and increased work of breathing.  For instance, they may reveal alveolar overdistension, or help determine the optimal level of PEEP (the so-called "critical opening pressure") for a patient with ARDS.

Relationship of pressure and volume to work of breathing
Work of breathing(elastic work+resistive work)=Pressure x volume 
Essentially, this means that the area under (or, to the left) of the pressure-volume loop is the work of breathing.

From this it becomes obvious, that anything increasing the convexity of the inspiratory curve, and anything pushing the whole loop to the right, will be increasing the work of breathing.
For instance, witness the work of breathing in the context of severe asthma.
Of course, in this setting the work of breathing is shared between the ventilator and the patient.
