Mechanism of respiratory negative pressure is pressure lower than the atmospheric pressure, whereas positive pressure is pressure that it is greater than the atmospheric pressure . Pulmonary ventilation comprises two major steps: inspiration and expiration . Inspiration is the process that causes air to enter the lungs, and expiration is the process that causes air to leave the lungs . R espiratory cycle (RR) is one sequence of inspiration and expiration.
Mechanical Ventilation It is machine used positive-pressure to given breath according to machine parameter and case of the patient . PARAMETER AND SITTING OF MV Mode ( Volume control , Pressure Control , MIX ) Fio2 (O2) Fraction of Inspired Oxygen . Tidal volume Vt : Tidal volume is the amount of air delivered with each breath . PEEP : Positive End Expiratory Pressure . Respiratory Rate (RR) I:E ratio of inspiratory time : expiratory time .
Management Mechanical Ventilation For Oxygenation - Fio2 - PEEP For Ventilation - Tidal Volume - Respiratory Rate
Initial setting of MV Volume Control mode Tidal volume ( Vt ) set depending on gander then ideal body weight and lung status , male from 400 ml to 450 ml , female 350 ml to 400 ml . Fio2 : 100% PEEP : 5 RR : 14 to 18 per minuet I:E ratio 1:2 After 15 to 30 miutes , check the ABG and CXR to do changes on the setting .
definition Portable ventilation or Transport ventilation: it is Mechanical ventilation we can use it if we need transfer intubated patient to any place inside or outside hospital For example : To another hospital To radiology To OR To ICU
