Respuesta :
To avoid hypoxemia, the nurse should give oxygen for 30 seconds after the last suction and before beginning the next.
How is endotracheal suctioning carried out?
The suction pressure should be between 120 and 140 mm Hg. To achieve this, unlock the suction control valve (thumb valve), fully depress the valve, and adjust the vacuum regulator. Just enough suction should be applied to efficiently remove secretions. The injury to the tracheal mucosa may increase with high negative pressure levels.
Can an endotracheal tube be suctioned?
Intensive care units routinely suction endotracheal tubes (ETTs) to remove mucus and maintain an open airway so that an intubated patient's oxygenation and ventilation can be maximized. Hypoxia may result with ETT suction because of oxygen suction from Alveoli and the lung.
