Pulmonary hygiene prevents atelectasis (the collapse of the alveoli of the lungs) and rids the respiratory system of secretions, [3] which could cause respiratory infections. It can also decrease pulmonary shunting, increase the functional reserve capacity of the lungs, and prevent respiratory infection after chest trauma. [4]
Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
To prevent atelectasis (collapse of the alveoli or atriums) at the end of expiration. To facilitate recruitment of collapsed airways. Alveoli can be compared to gas in water, as the alveoli are wet and surround a central air space.
Atelectasis can develop and, if unmanaged, lead to pneumonia and postoperative fever. Pneumonia is a major lung complication associated with increased morbidity and mortality, length of hospital stay, and likelihood of hospital readmissions. [ 2 ]
Saline instillation helps maintain lung expansion during the lavage process, preventing atelectasis (collapse of lung tissue). The total volume of saline used can vary but typically ranges from 15 to 20 liters per lung, administered in aliquots of 500 to 1000 ml. Exogenous surfactant may be administered to help restore normal lung function ...
Stop breathing or gasp. Become unresponsive. Not have a pulse. The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ventricular tachycardia.
The intent of lung volume reduction is to achieve the complete collapse (atelectasis) of an entire lobe of the lung in order to reduce volume in the chest, restore elastic recoil and improve breathing. Interlobar collateral ventilation can prevent this.
Positive airway pressure (PAP) is a mode of respiratory ventilation used in the treatment of sleep apnea.PAP ventilation is also commonly used for those who are critically ill in hospital with respiratory failure, in newborn infants (), and for the prevention and treatment of atelectasis in patients with difficulty taking deep breaths.
