Fundamental
B.4.2 Exhalation port for breathing gas
The exhaust port refers to an interface connected to a delivery pipe of an anesthetic gas purification system. Respiratory conical joints cannot be connected to this
Mouth match. It is also important that the exhaust port is designed not to be confused with the suction port during the use of the resuscitator.
B.4.4 Airbag inflation valve connector
The size of this fitting should be selected appropriately to prevent accidental connection with manually controlled demand valves.
B.5.2 Disassembly and assembly
Improperly assembled resuscitators cause improper operation or complete failure, which is a serious danger that can cause patients with insufficient ventilation.
B.5.3 Patient valve function after vomit contamination
The vomit on the resuscitator is quickly and effectively removed, and it is important to resume normal work with minimal disruption.
B.5.4.1 Drop test
It is very important that the resuscitator be able to withstand the violent shock caused by falling from ambulances or hospital beds.
B.5.5 Immersion
Resuscitators are often used in environments where they may be accidentally immersed in water. If the resuscitator is quickly removed from the water, it should remain functional.
B.5.6 Airbag inflation valve
It must be ensured that the airbag inflation valve is not accidentally replaced by a manually controlled demand valve. Demand valves can produce high-flow airflows that can cause
The patient valve of the resuscitator is stuck.
B.6.1 Oxygen supplementation and transported oxygen concentration
Although an oxygen concentration of 35% by volume is sufficient in some cases, it is used to treat severe hypoxemia during artificial respiration.
For patients, it is best to use an oxygen concentration of 85 or higher. When supplemental oxygen flow is 15L/min or below, it should be able to achieve this
Concentration; because the flow rate exceeding 15L/min is no longer within the normal calibration range of standard flowmeters for clinical adults, it may cause oxygen
Inaccurate flow control and stuck patient valve in the inspiratory position.
B.6.2 Expiratory impedance
The expiratory impedance should be as small as possible to make it easy to exhale gas, unless there are special clinical regulations to impose impedance.
B.6.3 Inspiratory impedance
The resuscitator should be designed so that when the operator connects to the patient's airway but the operator has not activated the
Excessive negative pressure.
B.6.4 Patient valve failure
In the case of high supplemental oxygen flow, the failure or stuck of the gas suction valve can cause the resuscitator to fail, causing excessive pressure on the patient. recovery
YY 0600.4-2013/ISO 10651-4..2002
The device is usually used under an oxygen flow rate of 15L/min, but the valve of the flowmeter can pass a flow rate of more than 30L/min. Follow the manufacturer's
It is important to use only accessories recommended by the manufacturer.
B.6.5 Patient valve leakage --- forward leakage
If the resuscitator has a forward leak design feature, the user should be informed to avoid the user mistakenly thinking that the leak is a malfunction.
B.6.6 Instrument dead space
The smaller the dead space volume of the instrument, the better, to limit repeated inhalation of exhaled gas.
B.6.7 Ventilation performance
When the patient starts breathing spontaneously for the first time, the negative pressure generated is very small. In this case, due to some design features of the patient valve
Insufficient, inspiratory and/or expiratory steps may be inadequate, which can lead to repeated inhalation of exhaled gas.
B.6.7.1 Conveying capacity
The typical tidal volume for adult lung ventilation is approximately 600 mL. The compliance and impedance listed in Table 1 represent the needs of adults and children
Possible compliance and impedance of artificial respiration. In order to make up for mask leaks, a height of 15 mL/kg is commonly used during artificial respiration.
The tidal volume requirement is normal. This is typical for artificial respiration in pediatrics and adults.
Experience has shown that. due to leaks and compliance changes during neonatal artificial respiration, in order to achieve a tide of 20 mL or less
For the air volume, a delivery volume of 20mL ~ 30mL needs to be set.
B.6.7.2 Pressure limits
Experience with artificial respiration of infants shows that inhalation pressure not higher than 4.5kPa (45cmH2O) will not cause lung injury, and can
Provide adequate tidal volume for most patients weighing less than 10 kg.
Artificial resuscitators for patients weighing more than 10 kg do not require the use of a pressure limiting system. However, pressure limits are used
It is necessary for the resuscitator of the control system to meet the tidal volume requirements specified in this section without the use of an override mechanism (Table 1). When airway pressure
When limited to 6kPa (60cmH2O) or less, in order to allow these patients to ventilate with low lung compliance and/or high airway impedance, the control
Installation is necessary.
Using a pressure limiting system, a resuscitator that limits airway pressure to 3kPa (30cmH2O) may not be suitable for children weighing less than 10kg
Children provide sufficient tidal volume with high airway impedance and/or reduced lung compliance.
B.7.2 Operating conditions
Resuscitators are likely to be exposed to extreme temperatures as described in 7.2, because such temperatures are frequently produced in various parts of the world where resuscitators are used.
Now.
