For people who are unresponsive and have no breathing or breathing, CPR is indicated if they’re most likely experiencing cardiac arrest. If a person has a pulse but is not breathing, artificial ventilation may be used.
However, this method should only be used if the patient is still alive and has a pulse. According to the guidelines of CPR, lay people should not be asked to check the patient’s pulse. Instead, they should be given the option to check their breathing.
Although CPR is considered futile in patients suffering from cardiac arrest, it’s still recommended. They can be revived by correcting their underlying cause, such as a tension pneumothorax.
