Hospitals-II

1.1K
Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Mechanical Ventilation I: Indication and Settings

4.2K
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Mechanical Ventilation II: Invasive Ventilation

1.3K
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Current Trends in Nursing II

2.0K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Equipments Used To Measure Blood Pressure

3.4K
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Summary

Electric hospital beds reduce nurses' perceived effort and postural load during patient care, despite longer task times. Patient dependency influences nursing interventions regardless of bed type. Further research is needed for efficient electric bed integration.

Area of Science:

  • Nursing
  • Ergonomics
  • Biomechanics

Background:

  • Hospital beds are crucial for patient care and nurse well-being.
  • Traditional hydraulic beds present ergonomic challenges for nursing staff.
  • Electric beds offer potential improvements in patient handling and nurse safety.

Purpose of the Study:

  • To compare biomechanical, postural, and ergonomic aspects of nursing tasks using electric versus hydraulic hospital beds.
  • To evaluate the impact of different hospital bed types on nurses' perceived effort and physical load.
  • To assess the influence of patient dependency on nursing interventions.

Main Methods:

  • Observational study of nurses performing real patient-assisting tasks.
  • Measurement of biomechanical, postural, and ergonomic parameters.
  • Comparison of electric and hydraulic hospital bed performance.
  • Assessment of subjective effort and force exertion.

Main Results:

  • No significant differences in adopted flexed postures between bed types.
  • Longer performance times observed with electric beds.
  • Electric beds demonstrated superiority in reducing subjective effort, force exertion, and lumbar shear forces.
  • Patient dependency influenced intervention duration and force, independent of bed type.
  • Nurses reported higher appreciation and reduced perceived effort and postural load with electric beds.

Conclusions:

  • Electric hospital beds are ergonomically superior for nursing tasks, reducing physical strain.
  • Despite longer task times, the benefits of electric beds in mitigating biomechanical risks are significant.
  • Addressing implementation challenges is crucial for optimizing the use of electric beds in clinical settings.
