Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA High-quality cardiopulmonary resuscitation (CPR) and defibrillation are the most important interventions for patients with cardiac arrest, and should be the first steps that rescuers perform. This is reflected in the American Heart Association's new "CAB" mnemonic. While rescuers were once taught the "ABCs" of cardiac arrest, they now learn "CAB" -...

2020
In pandemic times, medical staff is becoming a key resource in fighting the infection. To achieve the best medical care, relevant techniques and procedures have to be taught to medical staff to reduce the risk of infection. COVID patients often need mechanical ventilation due to progredient respiratory insufficiency, so an endotracheal intubation becomes a critical procedure in managing these patients. This procedure has an increased risk of infection due to aerosol formation and working with...

Here, based on a clinician’s point-of-view, we propose a two-model lower body positive pressure (LBPP) protocol (walking and squatting models) in addition to a clinical, functional assessment methodology, including details for further encouragement of the development of non-drug surgical intervention strategies in knee osteoarthritis patients. However, we only present the effect of LBPP training in improvement of pain and knee function in one patient through three-dimensional gait analysis. The...

The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Continuous Telemetric In Utero Tracheal Pressure Measurements in Fetal Lambs

2023
Optimization of occlusion pressure and duration required to improve lung hypoplasia with tracheal occlusion is essential to improve in utero corrective treatments for congenital diaphragmatic hernia (CDH). This study reports a new method for continuous measurement of the tracheal pressure in an occluded and unoccluded fetal lamb surgical model of CDH.
FAQs
Continuous Positive Airway Pressure applies a constant level of pressure that splints open collapsible upper-airway structures. This reduces obstruction while the patient continues to breathe spontaneously. Unlike support that delivers mandatory breaths, CPAP does not take over the breathing cycle; its principal effect is maintaining airway patency and supporting breathing conditions.
By maintaining functional lung volume, CPAP can support gas exchange in addition to reducing upper-airway obstruction. This effect is relevant when spontaneous breathing persists but respiratory support is needed. The clinical benefit therefore depends on both airway stability and the patient’s ability to continue generating their own breaths.
Interface fit, selected pressure, monitoring, and adherence all influence CPAP performance. A mask or nasal interface must deliver the prescribed pressure while remaining tolerable for the patient. Pressure that is not appropriately selected may limit effectiveness, whereas poor fit or discomfort can reduce adherence and compromise treatment.
Initiation requires choosing an appropriate mask or nasal interface, fitting it correctly, selecting a pressure level, and monitoring the patient’s response. Clinicians also assess comfort and ongoing adherence because these affect sustained use. This workflow helps connect the mechanical delivery of pressurized air with the patient’s clinical needs.
CPAP is a first-line treatment for obstructive sleep apnea, where collapsible upper-airway structures obstruct breathing. It can also support patients with selected forms of respiratory distress, including neonatal conditions, when spontaneous breathing remains present. The method is therefore applied across sleep-related obstruction and specific respiratory-support situations.
Monitoring should address breathing, gas exchange, interface fit, pressure selection, comfort, and adherence. These factors indicate whether the system is providing useful support and whether the patient can continue treatment. Careful observation also helps minimize discomfort and complications while preserving the intended effects on airway patency and respiratory function.
