Final answer:
Fluid resuscitation and CPR should begin as soon as possible, ideally within minutes of an incident. CPR should be started after an individual has been removed from water, and proper blood access and fluids should be readily available in cases of significant blood loss.
Step-by-step explanation:
Responding swiftly in emergency situations for fluid resuscitation is crucial, ideally within minutes after an incident. When someone experiences drowning and is rescued with an intact laryngeal spasm, which prevents water from entering the lungs, the chances of full recovery are increased if CPR (cardiopulmonary resuscitation) is initiated quickly. It is especially important to start CPR as soon as the individual is removed from the water since performing CPR in water is ineffective.
In cases of suspected blood loss, if there is a risk of losing at least 500 ml of blood, or 7 ml/kg in children, having the appropriate blood access and fluids available is necessary to begin fluid resuscitation. CPR standards advise that chest compressions should be at least 5 cm deep at a rate of 100 compressions per minute. Notably, the chance of successful resuscitation decreases as the brain remains without oxygen; brain cells can start to die within minutes of oxygen deprivation.
