Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

Holter Monitor: 24-Hour Monitoring

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Guidelines For Measuring Vital Signs

Guidelines For Measuring Vital Signs

Following these guidelines can help nurses accurately measure vital signs, assess changes in patient conditions, and provide timely treatment when necessary. Adhering closely to the guidelines ensures the accuracy and reliability of the results.
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.

Assessment of apical pulse

Assessment of apical pulse

Assessing the Apical Pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:

Assessment of blood pressure in brachial artery(two-step method)

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Summary

Consumer smartwatches show potential for monitoring children with cancer. However, a Withings smartwatch underestimated step counts compared to an accelerometer, limiting its use for activity tracking in this population.

Background:

Consumer smartwatches offer potential for continuous physical activity monitoring in children undergoing cancer treatment.
The validity of these devices for accurately measuring step count and heart rate in this specific population remains unestablished.

Purpose of the Study:

To evaluate the accuracy of a Withings smartwatch for monitoring step count and heart rate in pediatric patients undergoing cancer treatment.
To compare smartwatch-derived data against research-grade devices for validation.

Main Methods:

14 children and adolescents (aged 8-18) undergoing cancer treatment participated.
A Withings smartwatch was worn for 12 weeks.
Step count was validated against an ActiGraph accelerometer, and heart rate against a clinical monitor under resting conditions.

Main Results:

The Withings smartwatch significantly underestimated step counts compared to the ActiGraph accelerometer (e.g., 3154 fewer steps/day), with proportional bias observed.
No significant difference in resting heart rate was found between the smartwatch and the clinical monitor, though individual variability was noted.

Conclusions:

The Withings smartwatch exhibits minimal bias for resting heart rate but systematically underestimates step counts in pediatric cancer patients.
Current data suggest that smartwatch-derived step counts are not reliable for clinical benchmarking or goal setting in this population.
