Describe the mode of ventilator


The mode of ventilation refers to the way in which a mechanical ventilator delivers breaths to a patient. There are several different modes of ventilation, including:


Controlled mechanical ventilation (CMV): Also known as conventional or volume-controlled ventilation, this mode delivers breaths at a set tidal volume (volume of air delivered with each breath) and rate, regardless of the patient's own breathing efforts.


Assist-control (AC): This mode combines elements of CMV and spontaneous breathing, providing a set rate of breaths and also triggering breaths in response to the patient's own efforts.


Synchronized intermittent mandatory ventilation (SIMV): This mode delivers a set rate of mandatory breaths and allows for spontaneous breaths in between.


Pressure-controlled ventilation (PCV): This mode delivers breaths at a set pressure, rather than a set volume or rate.


Pressure-support ventilation (PSV): This mode provides a continuous stream of pressurized air to support spontaneous breathing efforts.


Continuous positive airway pressure (CPAP): This mode delivers a constant flow of pressurized air to maintain a positive pressure in the airways and prevent collapse.


Each mode of ventilation has its own indications and potential benefits and drawbacks, and the appropriate mode will depend on the patient's condition and the goals of treatment.

MRI OF CERVICAL SPINE Forms

Normal MRI  OF CERVICAL SPINE: Protocol: Plain MR of the cervical spine was performed using routine turbo spin sequences in multiplanar planes of axial, sagittal and coronal planes using head and spine coils.The sequences used were T1 & T2 Axial, T1 & T2 Sagittal, T2 fat supressed coronal. Findings: There is loss of normal cervical lordosis with straightening of the cervical spine. The vertebral marrow signals of the cervical vertebrae are of adult marrow. The vertebral heights are maintained at all levels. No evidence of vertebral collapse or focal altered signals is noted within the vertebral bodies. Posterior elements including the pedicles are free. The signal intensities of the annulus fibrosus and nucleus pulposus of cervical discs are relatively maintained at all levels.The  vertical heights of the cervical discs are relatively well-maintained. No remarkable disc bulges or anterior thecal intentations are seen.No evidence of cord com...
