Symptoms of respiratory failure depend on its cause, the levels of oxygen and carbon dioxide in your blood, and whether respiratory failure developed slowly over time or suddenly. You may start out with mild symptoms such as shortness of breath or rapid breathing, which may get worse over time. Acute respiratory failure can be a life-threatening emergency. Respiratory failure may cause damage to your lungs and other organs, so it is important to get treated quickly.
