The invention relates to a heated air cushion cover (1), in particular for heat regulation of patients during surgical interventions, having at least one first material layer (2), at least one second material layer (3) and having an air inlet opening, wherein the first material layer (2) and the second material layer (3) are connected to each other so that at least one hollow chamber (4) through which an air stream can flow is formed between the first material layer (2) and the second material layer (3) upon supplying the air stream to the heated air cushion cover (1) via the air inlet opening, wherein at least the second material layer (3) has a perforation (5) via which the air can escape from the hollow chamber (4) to the outside of the second material layer (3). According to the invention, a heated air cushion cover (1) having a homogeneous warm air output on the patient side is attained in that an air-permeable third material layer (6), which is at least partially connected to the second material layer (3), is arranged on the outside of the second material layer (3) and the third material layer (6) diffusely distributes the air stream penetrating the perforation (5) of the second material layer (3) upon passing through the third material layer (6).La invención se relaciona con una manta térmica con cámara de aire (1), en particular para la regulación de calor de pacientes durante intervenciones quirúrgicas, comprendiendo al menos una primera capa de material (2), al menos una segunda capa de material (3) y teniendo al menos una abertura de entrada de aire, estando conectadas entre sí la primera capa de material (2) y la segunda capa de material (3) de tal manera que se forma al menos una cámara (4) hueca entre la primera capa de material (2) y la segunda capa de material (3) a través de la cual una corriente de aire puede fluir al aplicar una corriente de aire a la manta térmica con cámara de aire (1) a través de la abertura de aire, teniendo al menos la segund
