Ventilator support or life support as defined at few instances is employing the use of a machine that helps the person to breath by maintaining the flow of air in the lungs. Patients on ventilators may be awake but are either too sedated or are unable to talk because of the tubing that is orally inserted, however, they do open the eyes and move them.
Non-invasive ventilation is the provision of breathing support which is administered through a mask either or nasal or oral. The air delivered is of slightly high pressure which may either be constant in case of CPAP or alternative in case of BiPAP.
Bi-phasic positive airway pressure is pressure-regulated ventilation support that allows unhindered constant respiration throughout the respiratory cycle and can also be defined as a modification of CPAP in terms of time-cycled alterations of the applied CPAP level. As a result of this time-cycled changes, further variations are also made in controlling pressure, time duration of every phase and the pressure levels that correspond to it.
The reason why the bi-level positive air pressure is more the preferred route to facilitate mechanical respiration of the individual is that renders a more progressive and smooth change from the control to the succeeding increased levels of mechanical respiration. Furthermore, it does not exhibit complications such as deciding the perfect moment to begin with the operation and contemplating further ventilatory management for the individual and the essential customization can be as per the patient depending on the blood gases study. Bi-phasic positive air pressure machine also render it easier to either increase or decrease the intensity of invasion without any complications. In addition, the continuous breathing does not initiate the need to switch on the ventilation mode and allows the patient to breath conveniently even if the most intense invasive conditions are prescribed.
