All are true about Air-embolism except

(D) Decreased residual volume # Venous Air Embolism:> Venous air embolism (VAE), the entry of gas into the peripheral or central vasculature, can occur secondary to iatrogenic complications, trauma, and even certain recreational activities.> Gas emboli are usually composed of air, but they can also occur with medically used gases such as carbon dioxide, nitrous oxide, and nitrogen. Although very small volumes of air can lead to severe sequelae, it is generally accepted that more than 50 mL of air can cause hypotension and dysarhythmias and more than 300 mL of air can be lethal.> Laboratory Studies> Arterial blood gases are indicated and usually demonstrate hypoxemia, hypercapnia, and metabolic acidosis.> Mild cases may demonstrate mild hypoxemia and hypocapnia.
