One of the most important goals of inpatient psychiatric care is to provide a safe and therapeutic environment for both patients and staff. A small number of aggressive or agitated patients are difficult to sedate, even after multiple doses of sedating antipsychotics. Adverse effects can result in harm to the patient and staff and that observations are conducted without touching the patient.
This study aims to determine if motion magnification can improve the feasibility of non-contact respirations monitoring over a video feed.
Registered nurses were invited to view seven pairs of pre-recorded footage of healthy volunteers and count the number of breaths that they observe over a period of one minute for each. One of the paired videos was unprocessed and the other magnified the motion of chest rise and fall.
Nursing observation of respirations showed an improvement in reduction of count error from 15.7 % to 1.5 % after video magnification of respiratory movement. Nurses also stated that viewing the processed video was much easier to make their observations from.
It is possible to use magnified video to monitor respirations of patients during circumstances where it is potentially difficult to obtain. Further observational studies should be conducted on a larger scale with this type of technique and is urgently needed to inform practice.
住院精神病护理最重要的目标之一是为患者和工作人员提供安全和治疗性的环境。少数具有攻击性或激动的患者即使多次服用镇静抗精神病药物也难以镇静。不良反应会导致患者和工作人员受到伤害，并且需要在不接触患者的情况下进行观察。
本研究旨在确定运动放大是否可以提高通过视频馈送进行非接触式呼吸监测的可行性。
邀请注册护士查看七对健康志愿者的预先录制的录像，并在一分钟的时间内观察并记录他们观察到的呼吸次数。其中一对视频未经过处理，另一对则放大了胸部起伏的运动。
在放大呼吸运动视频后，护理人员观察呼吸的计数误差从 15.7%降低到 1.5%。护士们还表示，观看处理过的视频更容易进行观察。
在某些情况下，有可能使用放大的视频来监测患者的呼吸，在这些情况下，可能难以获得。应该在更大的范围内对这种技术进行进一步的观察性研究，并迫切需要为实践提供信息。
