[clambert@uj.ac.za](clambert@uj.ac.za), P O Box 524, Auckland Park, 2006  \nABSTRACT  \nBackground: Peak flow meters (PFMs) measure the speed of airflow from the lungs during a forced exhalation. Current clinical practice guidelines advocate the use of PFMs in the management of acute asthma. No literature could be found describing local pre-hospital emergency care providers' use of PFMs. We aimed to investigate and describe a sample of prehospital emergency care providers' knowledge and use of PFMs in the management of acute asthma in Johannesburg, South Africa.  \nMethods: Fifty respondents (22 basic, 16 intermediate and 12 advanced life support providers) completed a pre-piloted questionnaire consisting of closed questions with pre-set response options focusing on exploring respondents' knowledge, understanding and use of PFMs.  \nResults: Responses highlighted a general lack of knowledge and understanding of PFMs. None of the basic life support providers, and only 19% of intermediate life support providers, indicated they had received training on the device. PFMs do not appear to be readily available in ambulances, with only 8% of the respondents indicating they had ever used a PFM on a real patient.  \nConclusion: A lack of training on the device and its apparent unavailability are concerning since the peak expiratory flow rate (PEFR) measurement for asthma cases is considered best practice, and literature shows that emergency medical service (EMS) providers are commonly dispatched to asthmatic cases. Additional training and further research on the value and use of PFMsin local pre-hospital emergency care contexts is therefore recommended.  \nVincent-Lambert C, Nkuna C.

These include pulse oximeters, allowing for non-invasive measurement and monitoring of oxygen saturation, as well as arterial and venous blood gas analysers.  \nSpirometers and peak flow meters (PFMs) are included in the range of devices available, both of which focus on physiological bronchodilatory responses.2,3 These portable handheld devices record a patient's ability to expel air and deliver a reading in litres per minute.4 Chest x-rays may also be of value in diagnosing asthma, as they mayshow evidence of hyperinflation. However, such radiological findings are often only noted during episodes of acute exacerbation; between `attacks', the lungs may appear normal.4 In prehospital settings, it is not currently a feasible option for local emergency care","cbCailj5pB7Dykcg","https://ap.wps.com/l/cbCailj5pB7Dykcg","pdf",703934,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusion\n# Background\n## Asthma and assessment tools\n## Role of PEFR and PFMs","[{\"question\":\"What was the study designed to investigate about PFMs?\",\"answer\":\"The study aimed to investigate and describe prehospital emergency care providers' knowledge and use of peak flow meters in managing acute asthma in Johannesburg, South Africa.\"},{\"question\":\"How were the respondents trained and how did that relate to PFM knowledge?\",\"answer\":\"Responses indicated a general lack of knowledge and understanding, with none of the basic life support providers and only 19% of intermediate life support providers reporting training on the device.\"},{\"question\":\"Did providers use PFMs on real patients?\",\"answer\":\"Only 8% of respondents indicated they had ever used a PFM on a real patient, suggesting limited availability and use in ambulances.\"}]","Pre-hospital emergency care providers' knowledge and use of peak flow meters in the management of acute asthma in Johannesburg, South Africa | PDF",1789928657]
