COVID-19 Pandemic and the Role of Control Room in the Tertiary Care Hospital

COVID-19 has been labeled a serious public health emergency globally. Due to its high infectivity it has led to an increased burden to the Medical Fraternity as well as the Government. Therefore, the need for preparedness as well as conventional intervention strategies became integral during such health emergencies. To monitor the implementation of proper activities and to manage the patient load with adequate safety of the staff, COVID control rooms were established in the hospital premises. The main objective of the Control Room is risk mitigation, planning strategies, alleviating concerns and addressing issues associated with the health emergency across the hospital and further delegating the information to the higher authorities and the Ministry. Hereby in this review we have tried to summarize the administrative structure, functions and limitations of the 24x7 Control Room established in Tertiary Care Hospital, New Delhi.

Analysis of noise reduction measures in a noise workshop handover control room / 中华劳动卫生职业病杂志

Objective: To explore the sound insulation, sound absorption and other noise reduction transformation methods in a noise workshop handover control room. Methods: In December 2021, through the occupational health investigation and on-site testing of the handover control room of a noise workshop, the causes of excessive noise were analyzed, and the transformation design scheme to reduce noise was proposed and the effect was analyzed. Results: Before the transformation, the peak frequency band noise intensity of the noise workshop handover control room was 112.8 dB (A), and the peak frequency was 1000 Hz. After noise reduction, the theoretical calculated control value was 61.0 dB (A), and the measured noise intensity was 59.8 dB (A) . Conclusion: The noise intensity of the handover control room is reduced after noise reduction, which is in line with the contact limit requirements of the control room in GBZ 1-2010 "Hygienic Standards for the Design of Industrial Enterprises", and has reference significance for noise control engineering.

The effect of increasing the illumination on operators' visual performance in the control-room of a combined cycle power plant

BACKGROUND: Lighting is one of the environmental factors affecting the performance of the control room operators. Therefore, the aim of this study was to compare the control room operators’ visual performance in two different illumination conditions at a combined cycle power plant through field-work. METHODS: Sixteen operators in day shift were evaluated with the Freiburg Visual Acuity test (FrACT) software at two lighting systems with different intensities. It includes the first phase with fluorescent illumination system (Power: 40 W, Color Temperature: 4000 Kelvin, Luminous Flux: 2780 Lumen and Model: Pars Shahab) and the second phase with a combined illumination system includes fluorescent and LED (Power: 48 W, Color Temperature: 4000 Kelvin, Luminous Flux: 5400 Lumen and Model: Mazinoor). RESULTS: Based on the results, visual performance index and visual acuity significantly increased after the intervention (p < 0.001). As to contrast, more lighting significantly reduced the percentage of recognized contrast (p < 0.001) and increased the contrast performance index (p < 0.001). CONCLUSIONS: The results of this study showed that increasing the intensity of light from the values below the allowable limit to the values above the allowable limit would increase the visual indicators in individuals.

Practice and Experience to Strengthen Inspection Monitoring in Drug Control Room / 中国药房

OBJECTIVE:To improve inspection in drug control room in order to ensure drug safety of patients.METHODS:The status quo and problems of drug control room were analyzed to put forward some measures for inspection monitoring,such as enhancing self-examination,quality assessment,equipment maintenance,regular training of test techniques and operation.RESULTS & CONCLUSIONS:The quality assurance system is improved by monitoring inspection in drug control room in various ways to ensure the accuracy and reliability of test data and drug safety of patients.

Status Quo and Development of Hospital Drug Control Room / 中国药房

OBJECTIVE:To enhance the function of the hospital drug control room(DCR)laboratory. METHODS: The status quo and the chief work carried out there of DCR were analyzed comprehensively. RESULTS: The function of the DCR has gradually extended from quality control of self-made drugs to the monitoring on hospital drug quality and solving of the problems encountered in clinical practice. CONCLUSIONS: The function of the DCR should be enhanced further to shift its focus from drug-centered to patient-centered so as to enhance hospital medical service level and promote rational drug use.

THE EFFECT OF IMPULSE NOISE ON HEARING OF GUINEA PIGS IN THE CONTROL ROOM OF MISSILE LAUNCHING VEHICLE / 解放军医学杂志

The present paper deals with the effect of impulse noise, which is produced by launching of miniature tactical missiles, on hearing of guinea pigs situated in the control room of the missile launching vehicle. 20 normal hearing guinea pigs are placed in the control room in which impulse noise level is 160-170dB (sound pressure level) and duration is longer than Is. 48h after sound exposure, the mean threshold shift is 2 dB, and threshold shift of 2/40 ears is greater than 10dB. Histological observation reveals that cochlear hair cells are undamaged in 15 ears. Howeves, staining on bloc shows hydrops of cochlear partition in 5 ears.
