![]() ![]() A typical initial applied PEEP is 5 cmH2O. Applied PEEP is generally added to mitigate end-expiratory alveolar collapse.For most patients, an initial respiratory rate between 12 and 16 breaths per minute is reasonable An optimal method for setting the respiratory rate has not been established.The appropriate initial tidal volume depends on numerous factors, most notably the disease for which the patient requires mechanical ventilation. The tidal volume is the amount of air delivered with each breath.A ventilator-delivered breath is initiated when the return flow is less than the delivered flow, a consequence of the patient's effort to initiate a breath When flow-by triggering is used, a continuous flow of gas through the ventilator circuit is monitored.When pressure triggering is used, a ventilator-delivered breath is initiated if the demand valve senses a negative airway pressure deflection (generated by the patient trying to initiate a breath) greater than the trigger sensitivity.There are two ways to initiate a ventilator-delivered breath: pressure triggering or flow-by triggering.Positive end-expiratory pressure (PEEP).Common trouble shooting examples with mechanical ventilation. ![]() Guidelines in the initiation of mechanical ventilation.Advantages and disadvantages between modes.
