Oxidative stress is caused when the equilibrium between free radical generation and antioxidant capacity is disrupted. Unfortunately, numerous clinical trials conducted using different antioxidants failed to prov

Modes of Invasive Mechanical Ventilation,tion, set to either target a desired pressure or volume. Pressure support ventilation is a partially supported, or spontaneous, pressure-controlled mode of ventilation with no set respiratory rate or tidal volume. The peak inspiratory pressure (PIP) represents pressures in the entire airway system a

Understanding the Ventilator Screen,y on the screens of each mechanical ventilator brand. There are a few key points to remember when reviewing ventilator screens. (1) The values set by clinicians are found on the bottom of the screen. The patient’s response is located at the top of the screen. (2) Data are provided in both numerical

,Placing the Patient on the Ventilator, The mode, tidal volume, respiratory rate, PEEP, inspiratory time/I:E ratio, and fraction of inspired oxygen should all be selected. Low tidal volume ventilation and targeting low pressures on the ventilator have been shown to improve outcomes for patients with and without acute respiratory distress

Specific Circumstances: Acute Respiratory Distress Syndrome (ARDS), interventions in critical care have been as reproducibly beneficial to patients as low tidal volume ventilation. Prevention of ventilator-induced lung injury is a key benefit of active ventilator management in the ED. In ARDS, as well as other patients, maintaining a plateau pressure of less than 3

Specific Circumstances: Asthma and COPD,re at risk for air trapping, manifesting as increased autoPEEP, which can lead to decreased venous return and hemodynamic instability. These patients require sufficient time to exhale, which can be achieved with low respiratory rates, low inspiratory to expiratory ratios (I:E ratios), low inspirator

Specific Circumstances: Neurologic Injury,jury. The goals for patients with neurologic injury are to maintain normoxia and eucapnia, with particular emphasis on avoiding hypocapnia, hypoxemia, and hyperoxia. Guidelines recommend targeting a normal PaCO. of 35–40, and monitoring frequent ABGs and capnography is very important in this patient
