The 'RESP' waveform on a hospital monitor is a respiratory waveform that measures a patient's respiration rate. The monitor measures the thoracic impedance between two ECG electrodes on the patient's chest, and changes in the impedance due to thoracic movement produce the Resp waveform on the monitor screen. Clinicians can use this to monitor for any respiratory problems, such as apnea or dyspnea.

'RESP' refers to a patient's respiration rate
In a hospital setting, RESP refers to a patient's respiration rate. That is, the rate at which they are breathing. A resting adult typically breathes 12 to 16 times per minute. Monitors that track respiration rate are an important tool for clinicians to monitor patients for respiratory problems, such as apnea or dyspnea.
The RESP waveform on a patient monitor is created by measuring the thoracic impedance between two ECG electrodes placed on the patient's chest. Changes in impedance due to thoracic movement are what produce the waveform.
Monitors that track respiration rate are just one type of patient monitor. Others include those that track heart rate, blood pressure, and body temperature. With the rapid development of medical technology, these monitors are being used more and more in hospitals to monitor patients' vital signs in real-time.
In addition to monitoring patients in hospitals, some monitors are designed to be used outside of clinical environments. For example, during patient transport in an ambulance or at home.

Clinicians can use the waveform to monitor respiratory issues
The "RESP" waveform on a hospital monitor measures the thoracic impedance between two ECG electrodes on a patient's chest. Clinicians can use this waveform to monitor and identify respiratory issues.
Ventilator waveforms are graphical descriptions of how a breath is delivered to a patient. They include three scalars: flow versus time, volume versus time, and pressure versus time, as well as two loops: pressure-volume and flow-volume. Scalars are representations of specific respiratory parameters over time, with pressure and flow being measured values and volume being a calculated value.
By understanding these scalars and their characteristic appearances, clinicians can evaluate a patient's respiratory mechanics and their interaction with the ventilator. For example, the pressure scalar can assess patient lung mechanics and their response to respiratory medications, while the flow scalar can help identify auto-PEEP and dyssynchrony, and the volume scalar can indicate ventilator circuit-related problems.
Additionally, clinicians can identify alterations in the waveforms that may indicate asynchrony or other issues. For instance, auto-triggering of the ventilator is evident when the respiratory rate suddenly increases without patient input, and this can be seen on the scalar waveforms as rhythmic breaths without a pause.
Understanding and interpreting these waveforms helps clinicians recognize problems, optimize ventilation and patient synchrony, and ultimately improve clinical outcomes and patient care.

The monitor measures thoracic impedance
The 'RESP' on a hospital monitor stands for the respiration rate. This is a respiratory measurement that is taken to monitor for any respiratory problems, such as apnea or dyspnea. To do this, the monitor measures thoracic impedance.
Thoracic impedance refers to the hindrance of the flow of the current carried by ions across the chest. It is related to the total amount of intrathoracic fluid. The electrical impedance of the thoracic cavity varies during breathing, with variations of about 0.2 Ω around a baseline of as much as 10 kΩ. The impedance increases as the patient inhales and decreases as they exhale.
A pair of electrodes are used to detect this impedance variation, and the voltage change can be measured on the same electrodes (2-wire respiration measurement) or on a different pair of electrodes (4-wire respiration measurement). The patient's position can impact the optimum respiration measurement. For example, if the patient is lying down, breathing tends to occur in the abdomen area, so Lead II or Lead III might provide the best 2-wire measurement.
The measurement of transthoracic impedance has been suggested to provide additional information for the early diagnosis of fluid overload.

The CDC's RESP-NET monitors hospitalizations associated with respiratory viruses
The "RESP" waveform on a hospital monitor is a respiratory waveform that measures a patient's respiration rate. Clinicians can monitor respiratory problems such as apnea or dyspnea using this waveform.
The CDCs RESP-NET Monitors Hospitalizations Associated with Respiratory Viruses
The CDC's Respiratory Virus Hospitalization Surveillance Network (RESP-NET) monitors laboratory-confirmed hospitalizations associated with respiratory viruses, including influenza, COVID-19, and respiratory syncytial virus (RSV) among children and adults. It is made up of three networks: FluSurv-NET, COVID-NET, and RSV-NET, which focus on influenza, COVID-19, and RSV, respectively.
RESP-NET provides an interactive dashboard that allows users to follow trends and compare hospitalization rates for these viruses across different demographic groups and over time. The rates are based on laboratory-confirmed cases and can be viewed by season, site, age group, sex, or race and ethnicity.
The CDC also collects RSV laboratory test results through the National Respiratory and Enteric Virus Surveillance System (NREVSS), a voluntary, laboratory-based surveillance system. NREVSS monitors seasonal trends of several viruses, including RSV, by collecting data on the number of tests performed and the number of positive cases.
The CDC's surveillance of respiratory viruses aims to inform clinical and public health responses, estimate disease burden, and respond to outbreaks. The data collected helps understand hospitalization trends and identify populations at the highest risk.
In addition to RESP-NET, the CDC has other surveillance initiatives, such as the New Vaccine Surveillance Network (NVSN) and the Investigating Respiratory Viruses in the Acutely Ill (IVY) Network, which focus on pediatric and adult populations, respectively. These networks provide valuable insights into respiratory virus-associated hospitalizations and contribute to our understanding of the impact of these viruses on different age groups.

Patient monitoring devices are increasingly compatible with electronic patient records
Remote patient monitoring (RPM) devices are becoming increasingly compatible with electronic patient records. RPM devices allow providers to monitor, report, and analyse their patient's acute or chronic conditions from outside the hospital or clinic setting. RPM devices help patients engage with and better understand their health on a daily basis. They also enable providers to make proactive clinical decisions. RPM devices include blood pressure cuffs, pulse oximeters, ECGs, stethoscopes, and heart rate monitors. These devices can measure a patient's heart rate, blood flow, blood oxygen levels, lung function, and other vital signs.
RPM devices are often compatible with Bluetooth, allowing them to send data in real time to clinicians. This data can be stored in electronic health records (EHR) systems and accessed through portals such as ClinicianConnect®. Some RPM platforms, such as MedM, offer compatibility with hundreds of IoT smart medical meters, monitors, sensors, trackers, and wearables. MedM users can sync their health data with Apple Health and Google Health Connect, allowing them to share their health records with trusted individuals.
Implantable devices are another form of RPM that are surgically placed inside a patient's body to monitor specific health conditions. These include implantable cardiac monitors and implantable glucose monitors. Mobile apps and smartphone-connected devices are also used for RPM, allowing patients to track their nutrition, physical activity, sleep, and other health metrics. These devices provide patients with accessible tools for lifestyle tracking and education about health self-management.
The effectiveness of RPM devices relies on their ability to operate within a unified system. This involves the implementation of specific software solutions that can interact with existing health IT infrastructure and EHR systems. Centralized data management practices are essential to ensure that data can be received, stored, and accessed securely. RPM devices with interoperability capabilities provide clinicians with a complete patient view, enabling early detection and more personalised care.
