1. What does medical PO2 mean? PO2 in medicine refers to the concentration of oxygen partial pressure in the blood. This is a very important indicator because it can tell doctors whether the bodys blood oxygen saturation is normal. When the blood oxygen saturation decreases, PO2 will decrease, which is usually caused by respiratory or cardiovascular diseases. Measuring PO2 can be very useful in the following conditions: shortness of breath or shortness of breath, chest pain, rapid or slow heartbeat, atrial fibrillation. PO2 is usually measured in millimeters of mercury, while the normal range for PO2 in humans is usually 80-100 millimeters of mercury. If the measured value is below this range, further examination and treatment may be necessary. When PO2 is below 60 mmHg, severe hypoxemia may occur, which can lead to tissue and organ damage. Therefore, doctors and nurses will attach great importance to this indicator. In cases of insufficient blood oxygen supply, methods such as nasal cannula, face mask, mechanical ventilation, or patient oral and upper airway can be used to increase PO2 levels. Severe hypoxemia may require oxygen therapy, which can be delivered to an oxygen flow meter using an oxygen powered device. These machines can supply oxygen to the patients breath according to the set flow rate and pressure. In severe cases, such as ischemic heart disease, surgical treatment equipment such as ECMO may be required to support the patients vital functions. Note: ECMO (extracorporeal membrane oxygenation) is a powerful cardiopulmonary support technique. It uses a device similar to the natural lungs of the human body to assist patients with artificial respiration, which is a very important treatment method.

>2. How to connect ECMO air mixture

The connection steps for ECMO air oxygen mixture are as follows

1. Before confirming the compatibility between the equipment and the air source, it is necessary to check whether the interface specifications of the air oxygen mixer and the air source (oxygen cylinder or central oxygen supply system) match.

2. The pipeline connection process should strictly follow the order of gas source → air oxygen mixer → oxygenator: Step 1: Connect the gas source to the air oxygen mixer. Connect the output end of the oxygen cylinder or the oxygen supply pipeline at the center of the delivery to the inlet of the air oxygen mixer, ensuring that the interface is fully inserted and locked to prevent gas leakage. Step 2: Connect the air oxygen mixer to the oxygenator. Connect the outlet of the air oxygen mixer to the inlet of the oxygenator of the ECMO system through a dedicated pipeline, and also confirm the sealing of the interface. 3. Set parameters and adjust the gas setting FiO ₂ (inhaled oxygen concentration). Based on the patients blood gas analysis results, set the target FiO ₂ (usually ranging from 21% to 100%) through the adjustment knob or digital panel on the air oxygen mixer. For example, when maintaining a patients SpO ₂ above 95%, it may be necessary to set FiO ₂ at 60% -80%. Adjust the gas flow rate according to the oxygenator model and patient needs (usually 1-15 L/min). Low flow rate may lead to i
