Background: Physiotherapeutic intervention body positioning have been observed to increase oxygen saturation.  In COVID-19 patients, we intended to investigate how the prone position worked in conjunction with conventional respiratory physiotherapy. The objective was to determine the effect of prone position along with conventional respiratory physiotherapy on SpO2 of COVID-19 patients in Aurobindo hospital, Indore district. Methods: The Ministry of Health, Government of India, authorized the rules for collecting data from infected patients. In this study, 400 patients between the ages of 20 and 80 years old were recruited from Sri Aurobindo Hospital in the Indore district, all of them had a confirmed diagnosis of COVID-19 and required oxygen treatment. SpO2 data was collected as a baseline. Patients were helped into the prone position after baseline data collection and conventional respiratory physiotherapy. Clinical data was obtained again after using the prone posture in conjunction with conventional respiratory physiotherapy. To demonstrate the various prone variations, a patient information sheet was supplied. At 0 and 60 minutes after the exercise, oxygen saturation was measured. Results: Between April 2020 to June 2020, we assessed SpO2 of 400 Patients pre and post prone position along with conventional respiratory physiotherapy. Prone positioning was feasible. Oxygenation was significantly improved from supine to prone position. The data were processed for mean and standard deviation. It was analyzed that there was difference in pre to post value of mean, from 95.685 to 98.123 with standard deviation from 1.645to 1.445. The result shows significant improvement in SpO2 after applying prone positioning in patients infected with COVID-19. The findings suggest that prone positioning is both possible and beneficial in increasing blood oxygenation in awake COVID-19 patients. Further study is needed to find the technique's potential value in terms of enhancing overall respiratory and global outcomes. Conclusion: The difference between the saturation of the two position was significant.

Background. The standard electrocardiogram (ECG) is commonly performed in the supine posture. It may be difficult to report ECG in a supine posture for those who are unable to adopt the supine posture because of certain circumstances such as acute respiratory distress syndrome—patients who are placed in a prone position for long periods to improve oxygenation. Few data are available on the impact of the prone position on the ECG recording with electrodes on the posterior chest. Examining and analyzing the type and extent of changes observed in the prone ECG in healthy adults have become vitally valuable. Methods. A cross-sectional observational study enrolled forty healthy adults (24 males and 16 females) aged between 18 and 40 years. The ECG was performed in two different body positions, supine and prone. Influence of prone position on the heart rate, mean QRS axis, amplitude, morphology, duration, mean T wave axis and polarity, mean P wave axis, PR, and mean QTc duration was evaluated. Results. The mean heart rate was higher in the prone position (73.2 ± 12.4 bpm) compared with the supine position (69.5 ± 11.5 bpm, p = 0.03). The QRS duration decreased considerably from supine (92.8 ± 12.6 ms) to prone (84.9 ± 11.9 ms, p < 0.001 ). The mean QRS axis moved to the left in the prone posture (40.5° ± 32°) relative to the supine (49° ± 28°, p = 0.015 ). The QRS amplitude in the precordial leads was significantly decreased from supine (7.42 ± 3.1 mV) to prone (3.68 ± 1.7 mV, p < 0.001 ). In addition, changes in the QRS morphology in leads V1–V3 with the appearance of new Q waves were noted. A notable variation in the mean corrected QT (QTc) period with decrease in duration in prone posture ECG (385 ± 64.8) relative to supine (406 ± 18.8, p = 0.05 ). Conclusions. Prone position ECG resulted in significant changes in healthy adults that should be aware of this as this can affect diagnosis and management strategies. Further studies are needed to investigate the impact of prone position on ECG recording in patients with cardiovascular diseases.

Introduction and Aim: It has been observed that recovery from COVID-19 is delayed due to continuation of myalgia, fatigue, headache and some respiratory problems even after the discharge from the hospital. Reports indicate the improvement of sensory, cardiorespiratory and psychological functions following practice of Prone asanas and Pal’s pranayama. Therefore, we conducted a pilot study to assess if practice of asanas in prone posture and slow breathing exercise of Pal’s pranayama schedule can facilitate recovery from the COVID-19 illness and alleviate post-recovery complications in these patients. Materials and Methods: This is an interventional pilot study conducted in COVID positive patients. A structured module of prone asanas and Pal’s pranayama schedule was given to the COVID positive patients in addition to the routine medical treatments and their stress levels were assessed prior to and after the practice. Also, the acute effects of asana-pranayama schedule on the improvement of cardiorespiratory functions and occurrence of other complications in the recovery phase was recorded. Results: Following practice of asana-pranayama schedule, the patients recovered faster from myalgia, fatigue, headache and respiratory problems and they had a feeling of well-being. Further, the complications in the recovery phase of COVID-19 were prevented and the intensity of stress was reduced with the practice of asana-pranayama schedule. Conclusion: This pilot study has shed some light on the early recovery and the prevention of complications in the recovery phase of COVID-19.

Rigid flow deflectors are usually used on water flow beds to protect engineering structures such as breakwater in coasts and to regulate flow routes in open channels. To reduce its side-effects, i.e., local scour at the toe of deflectors, a flexible flow deflector is proposed, and the corresponding local scour was investigated in this study. A flume experiment was conducted to investigate local scour. To show the advantage of flexible deflectors, a control experimental test was also conducted using a traditional rigid deflector under the same blockage area configuration and the same flow conditions. The flow field near the flexible deflector was also measured to reveal the local flow field. The results show that the bed-scour develops near the toe edges of both flexible and rigid deflectors, but the maximum and averaged scour depths for the flexible deflector are smaller. This advantage of flexible deflector in scour depth is mainly caused by its prone posture, which induces the upward stretching and enlarging horizontally rotating vortex and the upward shifted vertically rotating vortex. The former dissipates more turbulent energy and the latter results in smaller bed shear stress, which lead to smaller scour depth directly. In addition, the up- and down-swaying movement of the flexible deflector can also assistant to dissipate more turbulent energy, thereby damping the intense of the horseshoe vortices and thus weakening scour depth as well. The results of this study provide an elementary understanding on the mechanisms of a flexible flow structure and an alternative deflector-device to reduce scour depth.

Background The literature on ventilation (V) and lung perfusion (Q) distributions during general anesthesia and controlled mechanical ventilation in supine and prone position is contradictory. The authors aimed to investigate whether V, Q, and ventilation to perfusion ratio (V/Q ratio) matching in anesthetized and mechanically ventilated volunteers are gravity dependent irrespective of posture. Methods Seven healthy volunteers were studied at two different occasions during general anesthesia and controlled mechanical ventilation. One occasion studied ventral to dorsal V and Q distributions in the supine posture and the other in the prone posture. Imaging was performed in supine posture at both occasions. A dual radiotracer technique and single photon emission computed tomography were used. V and Q were simultaneously tagged with Tc-Technegas (Tetley Manufacturing Ltd., Sydney, Australia) and In-labeled macroaggregates of human albumin (TechneScan LyoMAA, Mallinckrodt Medica, Petten, The Netherlands), respectively. Results No differences in V between postures were observed. Q differed between postures, being more uniform over different lung regions in prone posture and dependent in supine posture. The contribution of the vertical direction to the total V/Q ratio heterogeneity was larger in supine (31.4%) than in prone (16.4%) (P = 0.0639, two-tailed, paired t test) posture. Conclusions During mechanical ventilation, prone posture favors a more evenly distributed Q between lung regions. V distribution is independent of posture. This results in a tendency toward lower V/Q gradients in the ventral to dorsal direction in prone compared with supine posture.
