|Intubation||Device: Biphasic Cuirass Ventilation||Not Applicable|
Patients who are deemed to meet inclusion criteria and none of the exclusion criteria will be preoxygenated by any of the acceptable standard preoxygenation strategies (non-rebreather face mask, noninvasive positive pressure ventilation, etc.) . Patients will be placed and maintained on continuous 3-lead cardiac, automatic blood pressure, pulse oximeter, and waveform capnography monitoring for the duration of the procedure. Prior to induction, and during the pre oxygenation phase, subjects will be placed on the Biphasic Cuirass Ventilation (BCV) device per the manufacturer's guidelines. After adequate preoxygenation has been achieved (as determined by the treating emergency physician), the BCV assisted ventilations will be maintained and standard of care intubation procedures including apenic oxygenation if ordered by attending emergency physician will be utilized. BCV will be discontinued upon confirmation of proper tracheal intubation by waveform capnography.
Safety The BCV device covers the anterior chest wall, and therefore, it cannot be in place if CPR is needed. Therefore, all patients in cardiac arrest will be excluded. Investigators will be excluding patients with a pacemaker or central line which impairs the ability of the Curiass shell to secure on the anterior chest. Finally, patients with a history of valvular heart disease will be excluded. The protocol directs the device be applied during the normal preoxygenation period (~within that 3-5 minute period of time prior to the administration of the induction and paralytic medications). There are no other known side effects of this device. There is a potential for the device application to delay the intubation attempt; however, it is not known whether delaying intubation ,while augmenting a patient's breathing with the BCV device, negatively impacts the patient's condition. The data collection form explicitly asks the intubating physician thinks that the device delayed the intubation attempt in any way. The data collection form also tracks all of the relevant time milestones. Both of these items will be reviewed periodically during the study as safety endpoints by the data monitoring committee and will be included in the manuscript results.

Experimental: Biphasic Cuirass Ventilation
Patients requiring emergent intubation in the Emergency Department will be provided ventilation during the apnic phase of intubation via the use of BCV.
Device: Biphasic Cuirass Ventilation
The RTX Respirator will be applied to the patient's chest to provide non-invasive ventilatory support using a Biphasic Cuirass Ventilation technology to increase the safe apnic period during intubation.

- Composite Primary Endpoint is the composite prevalence of any desaturation defined as SPO2 < 95% or Bradycardia, HR <60 beats per minute sustained for at least 30 seconds [ Time Frame: 0 to 5 minutes after intubation ]The primary outcome measure is the composite prevalence of any desaturation defined as SPO2 < 95% or Bradycardia, HR <60 beats per minute sustained for at least 30 seconds, during and in the immediate post intubation (5 minutes after tracheal intubation is confirmed) period.
- Prevalence of post-paralytic Bag valve mask use [ Time Frame: Time from paralytics administered until proper endotracheal tube placement is confirmed. ]Prevalence of post-paralytic administration bag valve mask ventilation in subjects enrolled into trial. We will describe this with a percentage and surrounding 95% confidence interval. This outcome reflects the potential need for ventilation during and around the intubation attempt. Our hypothesis is that BCV will eliminate the physiologic need for BVM rescue ventilation between the time paralytics are administered until the endotracheal tube is confirmed to be properly placed.
- Waveform capnography pattern [ Time Frame: Baseline to 30 minutes after intubation ]The investigators will describe the pattern of waveform capnography as measured by the research nasal capnography monitor. The waveform capnography trends will be represented graphically as continuous data for each subject over time to reflect the patterns observed from baseline until endotracheal tube is successfully placed in the trachea.
- Change in End-Tidal Carbon Dioxide (ETCO2) values [ Time Frame: Period of time from acquiring baseline ETCO2 value to successful intubation. ]We will describe the change in the mean +/- SEM and median +/- IQR ETCO2 values as measured from baseline to intubation.
- Blood Pressure response to the BCV device [ Time Frame: Baseline vital signs to 30 Minutes after intubation ]Investigators will describe the physiologic response to the BCV device by graphically representing each subject's systolic, diastolic, and mean arterial pressures (mmHG) in serial 5 minute measurements obtained from the immediate pre-application of the BCV device period until 30 minutes after intubation is complete. Unit of measure= mmHG
- SpO2 response to pre-oxygenation attempts BCV application [ Time Frame: Baseline vital signs to 30 Minutes after intubation ]Investigators will describe the physiologic response to the BCV device by graphically representing each subject's oxygen saturation measurements obtained from the immediate pre-application of the BCV device period until 30 minutes after intubation is complete. Unit of measure= % oxygen saturation
