The transport of virus-laden aerosols from a host to susceptible person is governed by complex turbulent airflow and physics related breathing, coughing sneezing, mechanical passive ventilation, thermal buoyancy effects, surface deposition, masks, air filtration. In this paper, we study the infection risk via airborne transmission on an urban bus using unsteady Reynolds-averaged Navier–Stokes e...

We planned to undertake a comparative study of the effect of short term (three weeks) training in savitri (slow breathing) and bhastrika (fast breathing) pranayams on respiratory pressures and endurance, reaction time, blood pressure, heart rate, rate-pressure product and double product. Thirty student volunteers were divided into two groups of fifteen each. Group I was given training in savitr...

Power spectral analysis of electrocardiogram (ECG) R-R intervals is useful for the detection of autonomic dysfunction in various clinical disorders. Although both panic disorder (PD) and major depressive disorder (MDD) are known to have effects on the cardiac autonomic nervous system, no previous study has tested this among drug-naïve (i.e. no history of treatment) patients with MDD and PD in t...

Relaxation techniques, such as deep breathing and muscle relaxation, are aspects common to most forms of mindfulness training. There is now an abundance of research demonstrating that mindfulness training has beneficial effects across a wide range of clinical conditions, making it an important tool for clinical intervention. One area of extensive research is on the beneficial effects of mindful...

Respiratory adverse events are not rare in pediatric anesthesia. The risk of airway complications must be considered before anesthesia. The current study was designed to determine the incidence and risk factors for adverse respiratory events in children undergoing general anesthesia. The study population included 682 children from neonates to 14 years who were presented for an elective or emerg...

This study aims to evaluate the viability of a clinical model of remote ischemic preconditioning (RIPC) and its analgesic effects. It is a prospective study with twenty (20) patients randomly divided into two groups: control group and RIPC group. The opioid analgesics consumption in the postoperative period, the presence of secondary mechanical hyperalgesia, the scores of postoperative pain by ...

BACKGROUND Heart surgery is associated with an occurrence of pulmonary complications. The aim of this study was to determine whether pre-surgery respiratory physiotherapy reduces the incidence of post-surgery pulmonary complications. METHODS Observational study of 263 patients submitted to off-pump coronary artery bypass grafting (CABG) surgery at the A Coruña University Hospital (Spain). 159...
