Role of Application of SWCR Guidelines in Management of Right Trochanter Pressure Injury (PI)
Abstract: A pressure injury refers to the localized death of tissue resulting from sustained pressure on the skin and underlying tissues. This damage is often compounded by shear forces or direct trauma to the skin. While terms like “decubitus ulcer,” “bedsore,” and “pressure sore” are commonly used interchangeably, they fail to capture the complexity of the condition as accurately as the term “pressure injury” does. The term “decubitus” originates from Latin, …

A Quasi-Experimental Investigation of The Effects of Two Different Negative Pressure Levels During Open Endotracheal Tube Suctioning on Physiological Parameters in Mechanically Ventilated Patients in The PCCM ICU At Pt. B.D. Sharma P.G.I.M.S., Rohtak
Abstract: Introduction: Patients who are intubated often have difficulty clearing secretions through coughing. As a result, endotracheal suctioning is essential to minimize the risk of consolidation and atelectasis, which could impair ventilation. However, suctioning can pose several risks and complications, including bleeding, infection, atelectasis, hypoxemia, cardiovascular instability, increased intracranial pressure, and potential damage to the tracheal mucosa. The level of negative pressure applied during suctioning plays a crucial role in the …
