Study Description
Brief Summary:
The aim of this study is to investigate the predictive value of the presence or absence of cardiac activity by bedside ultrasound during cardiac arrest. The investigators anticipate based on previous research that patients who suffer a cardiac arrest and have cardiac activity on bedside ultrasound will have a greater chance of surviving to hospital admission. The investigators hypothesis is that the mortality rate in patients in cardiac arrest with no cardiac activity by ultrasound will have a mortality rate of 100%.

Outcome Measures

Primary Outcome Measures :
  1. Number of patients that survive to Hospital Discharge [ Time Frame: Up to 12 months ]
    Participants will be followed for the duration of hospital stay, an expected average of up to 12 months. The time frame is an estimate based on previous research. Patients could survive hours to days to weeks or months.

Secondary Outcome Measures :
  1. The number of patients that demonstrate a Return of Spontaneous Circulation [ Time Frame: Up to 60 Minutes - ]
    Participants will be followed until a demonstrated return of spontaneous circulation (i.e. regain a pulse and blood pressure) is present - an expected average of up to 60 minutes. The time frame is an estimate based on previous research but is in the order of minutes.

  2. The number of patients that survive to hospital admission [ Time Frame: Up to 24 hours ]
    Surviving participants will be followed to hospital admission- an expected average of up to 24 hours. The time frame is an estimate based on previous research. Patients could survive minutes to hours before they are admitted.
