– How Assisted ventilation works: the device must read and recognize the patient effort and follow its lead to achieve better results. This effort appears for the device as unexpected change in pressure, volume or flow.

– Mandatory versus spontaneous breath: A spontaneous breath is one where the patient initiates (triggers) and cycles the inspiration. If the machine triggers or cycles the inspiration, the breath is considered mandatory. Thus, while spontaneous breaths can be either assisted or unassisted, mandatory breaths are always assisted by definition.

– Nebulization: The role of nebulizer is to pump nebulized medicine into the patient lungs during inspiration and it is mostly connected with the ventilation machine.

– Tube or NIV applications: The connection of the patient with the Ventilation machine could be done using tube. Or Non-invasively through a nasal or full facemask where the term “NIV” is used.

– Ventilation Mode: The term ”Mode” referees to particular setting on the device that controls the pattern of responses or actions the device conduct to assist or control breathing process.

– Volume Control means that device guarantees specific volume to be inhaled at inspiration at every breath or at specific amount of time. On the other hand, Pressure Control means that device guarantees specific set for inspiratory and expiratory pressure at every breath.

– Ventilation machine maneuvers: Most ventilation devices have special maneuvers that manufacturers claim they provide benefits to the patient at specific conditions.

– Waveform representation: Every ventilation machine should display the parameters of the patient related to the breathing process as waveform on the screen or loops on order to keep the track of monitoring patient condition and describes how the breath is delivered.

– Alarm system: Every Ventilation machine is provided with alarms and monitoring for the patient parameter to inform the stuff about threatening or critical changes happens to the patient conditions. Those alarms should be adjustable by device operator to fit the condition of the patient in terms of allowed or prohibited ranges.

– Device Sensors: Every ventilation device has set of sensors for different breathing variables such as Flow, pressure, CO2, O2 etc…these sensors enable the device to control and monitor the values of the breathing variables. These sensors must be high quality sensors, calibrated and checked every now and then to ensure the correctness and accuracy of their measurements.
