The larynx, pharynx, and epiglottis are all structures located in the upper airway, responsible for the passage of air during breathing and swallowing. Alveoli are small air sacs located in the lungs where gas exchange (oxygen and carbon dioxide) occurs, not in the upper airway.
As an EMR, the most likely interventions you would perform at the scene of a cardiac arrest include CPR (cardiopulmonary resuscitation) and the use of an AED (automated external defibrillator). These are critical initial steps in managing cardiac arrest to help maintain blood circulation and deliver a shock if indicated by the AED. EMRs are trained to assess and initiate basic life support measures promptly until more advanced medical personnel arrive.
Gastric inflation is likely to cause vomiting, aspiration, and even the development of pneumonia.
Apnea translates to "without breathing" in medical terminology.
Compressions should be performed at a rate of at least 100/min.
The ratio of compressions to breaths for a child with just one rescuer is 30 to 2.
In the scenario where a 60-year-old man is found in cardiac arrest inside his car with no apparent vehicle damage, the appropriate action is to carefully remove him from the vehicle while providing support to his head and neck. This technique ensures that the patient's spine is stabilized as much as possible during extraction. Once safely removed, CPR and other resuscitative measures can be initiated promptly.
If a choking patient becomes unresponsive, immediately activate the emergency response system.
The epiglottis is a flap of tissue that covers the entrance to the larynx (voice box) during swallowing, preventing food or liquid from entering the airway.
For CPR guidelines, a patient is considered an adult at the onset of puberty.
The risk of infection from performing CPR is extremely low however OSHA requires all healthcare workers to use standard precautions.
