This medical gas blend consists of nitrogen, oxygen, and carbon dioxide. It is specifically formulated to aid healthcare professionals in conducting hypoxic challenge tests, which are vital in evaluating patients' respiratory responses in low-oxygen conditions. The blend plays a crucial role in diagnosing conditions such as sleep apnea, chronic obstructive pulmonary disease (COPD), and hypoxemia. It is a colorless, odorless, and non-flammable gas mixture that is suitable for use in medical facilities and by healthcare providers. This mixture is a specialized calibration or medical-grade gas containing \(7.65\%\) Carbon Dioxide (\(CO_{2}\)), \(5\%\) Oxygen (\(O_{2}\)), and Nitrogen (\(N_{2}\)) as the balance. Typically used in medical, research, or clinical, blood-gas analysis applications.
