Which technique is commonly used to conserve SCBA air?

The technique commonly used to conserve SCBA air is known as skip breathing. This method involves taking a breath and then intentionally pausing between inhales. By not inhaling continuously, firefighters can extend the duration of their air supply while remaining calm and focused. Skip breathing allows the individual to take fuller breaths when they do inhale, which enhances their ability to utilize the air more efficiently.

In contrast, controlled breathing focuses on managing one's breath in a calm and steady manner, but it might not specifically optimize air conservation as skip breathing does. Deep breathing emphasizes taking larger breaths deeply and fully, which can utilize more air in a short period. Rapid breathing, on the other hand, increases the rate of air consumption and is not effective for conserving air while in the field. Thus, skip breathing is the most effective technique when the goal is to maximize the use of SCBA air supply during operations.
