Background: Respiratory physiotherapy (RPT) is an integral part of the management of patients in intensive care units (ICUs). The effective elimination of airway mucus is one of the most important factors that permits successful use of ventilation support. Manual hyperinflation (MH) and Expiratory rib cage compression (ERCC) or squeezing are methods of RPT that performed by professionally trained nurses in ICUs before endotracheal suctioning to re-expand collapsed alveoli (atelectasis),mobilize and remove excess bronchial secretions, and improve oxygenation in mechanically ventilated patients Aim: The aim of the current study was to investigate the effect of manual hyperinflation and rib cage compression on arterial blood gases results of mechanically ventilated patients. Research hypothesis: Mechanically ventilated patients receiving manual hyperinflation and expiratory rib cage compression before endotracheal suctioning will have improved arterial blood gases parameters as compared to those who will not. Sample: A purposive sample of 73 adult male and female mechanically ventilated patients for more than 24 hours. Setting: The study was carried out at different intensive care units at El-Manial University Hospital, and Medical critical care units that are affiliated to Cairo University. Tools: Two tools were utilized to collect data pertinent to the study: personal demographic and medical characteristics data tool and arterial blood gases (ABGs) monitoring chart
