BACKGROUND The assessment of the work of breathing in the definitions of respiratory failure is vague and variable. OBJECTIVE Identify a parsimonious set of signs to describe the work of breathing in hypoxemic, acutely ill patients. METHODS We examined consecutive medical ICU patients receiving oxygen with a mask, non-invasive ventilation, or T-piece. A physician inspected each patient for ...

BACKGROUND Respiratory rate is an important measurement in patient care, but accurate measurement is often difficult. We have developed a simple non-invasive device to measure respiratory movements in clinical circumstances, with minimal interference with the patient. We investigated respiratory patterns in patients receiving postoperative morphine analgesia to assess the capacity of the device...

Asthma, diabetes, hypertension, or major depression are non-communicable diseases (NCDs) and impose a major burden on global health. Stress is linked to both the causes and consequences of NCDs and it has been shown that biofeedback-based breathing trainings (BBTs) are effective in coping with stress. Here, diaphragmatic breathing, i.e. deep abdominal breathing, belongs to the most distinguishe...

Background: There is currently no consensus on the indication and benefits of breathing exercises for the prevention of postoperative pulmonary complications (PPCs) and for the recovery of pulmonary mechanics. Objective: To undertake a systematic review of randomized and quasi-randomized studies that assessed the effects of breathing exercises on the recovery of pulmonary function and preventio...

Inspection of the thorax identifies the breathing position adopted by the patient, the shape of the thorax, the dynamics of respiration (breathing pattern, symmetry of expansion, mechanics and synchrony of rib cage and abdominal movements). Inspection of the neck adds useful information, particularly with respect to the dynamics of breathing. Palpation ascertains the signs suggested by inspecti...

Breathing motion leads to a significant displacement and deformation of organs in the abdominal region. This makes the detection of the breathing phase for numerous applications necessary. We propose a new, purely image-based respiratory gating method for ultrasound. Further, we use this technique to provide a solution for breathing affected 4D ultrasound acquisitions with a wobbler probe. We a...

PURPOSE To assess the temporal and spatial accuracy of the GateCT™ system (VisionRT, London, UK), a recently released respiratory tracking system for 4DCT, under both ideal and nonideal respiratory conditions. METHODS Three experiments were performed by benchmarking and comparing its results with the ground-truth input data and those generated by the widely used Varian RPM™ system (Real-time ...

Appropriate wound healing is a crucial phase of surgical patients’ management, as it facilitates early mobilization and return to everyday life. Also, required before offering patients the next treatment. Surgical closure techniques have evolved remarkably; they include simple sutures, clips, adhesive compounds. Some appliances are used support closed wounds assist abdominal wall muscles’ movem...

Purpose The purpose of this study was to determine the effects of forced inspiration and forced inspiration and forced expiration exercise on stroke patients’ trunk muscle activity, trunk control ability. Methods Twenty four patients with stroke were randomly assigned to a control group with physical therapy and a complex breath exercise as well. The complex breath exercise group received physi...
