When assessing an unresponsive elderly man, what is the first action you should take?

In assessing an unresponsive elderly man, the first action taken should be to grasp the angles of the lower jaw and lift. This maneuver is crucial because it opens the airway, which is essential in any patient who is unresponsive and may not be breathing adequately or at all. Ensuring that the airway is open allows for further assessment of the patient's breathing and circulation and is part of the basic airway management protocol.

When a patient is unresponsive, there may be an obstruction due to the tongue falling back into the throat, which can block the airway. By lifting the jaw, you can create a clear pathway for air, which is critical for effective ventilation and oxygenation. After establishing an open airway, the responder can then check for breathing and pulse, or proceed with appropriate interventions depending on the findings.

Checking for a pulse or performing a head tilt before ensuring the airway is clear can lead to complications if the airway is obstructed. Starting CPR immediately may also not be warranted unless there is no breathing or pulse present after the airway has been assessed. Thus, managing the airway first is a fundamental step in life-saving measures.
