M paw — Mean airway pressure; E PAP — Pressure applied to exhalation; I PAP — Pressure applied to inhalation; P high — Highest pressure attained, similar to P ip; this is a constant pressure. P low — Pressure that P high drops to during expiratory time (T low) PEEP — Positive end-expiratory pressure, pressure created by a ...

Bag valve mask. Part 1 is the flexible mask to seal over the patients face, part 2 has a filter and valve to prevent backflow into the bag (prevents patient deprivation and bag contamination) and part 3 is the soft bag element which is squeezed to expel air to the patient
The NIOSH air filtration rating is the U.S. National Institute for Occupational Safety and Health (NIOSH)'s classification of filtering respirators.The ratings describe the ability of the device to protect the wearer from solid and liquid particulates in the air.
A pressure-time graphic. Airway pressure release ventilation (APRV) is a pressure control mode of mechanical ventilation that utilizes an inverse ratio ventilation strategy. . APRV is an applied continuous positive airway pressure (CPAP) that at a set timed interval releases the applied pre
A RSBI score of less than 65 [3] indicating a relatively low respiratory rate compared to tidal volume is generally considered as an indication of weaning readiness. A patient with a rapid shallow breathing index (RSBI) of less than 105 has an approximately 80% chance of being successfully extubated, whereas an RSBI of greater than 105 virtually guarantees weaning failure.

Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation.The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
