- Neurological problems: cerebrovascular accident (CVA), convulsions and cerebral hemorrhage.
- Breathing problemsrivers: respiratory failure, pneumothorax, acute asthma and pulmonary embolism.

Until medical rescue arrives, it is possible for the patient's companion to perform cardiac resuscitation, an important first aid procedure.
Important:Given the high mortality rate associated with sudden illness, it would be essential to have automatic external defibrillators (AED) in easily accessible locations for a response. quickly, especially in cases of cardiac arrest, as they are simple to use and can be operated by people outside the healthcare field to help the heart recover its function. beats. In addition, raising awareness among the population about the subject and offering first aid and emergency care courses Domestic emergency situations can also contribute to avoiding deaths due to sudden illness, speeding up emergency procedures. help.
