Recovering fully from COVID-19 is going to take more than some warm blankets and chicken soup. This 3-piece P.A.C.E.R. (Post-Acute COVID-19 Exercise and Rehab) Kit was specifically developed to help keep track of recovery progress as well as repair damage to the lungs and respiratory system in pediatric patients who are coming back from this disease or any cardiopulmonary condition. This kit allows recovering children to rehabilitate their respiratory systems at their own pace and comfort level. The Baseline Fingertip Pulse Oximeter quickly and easily provides immediate feedback to the patient on the current status of their blood oxygen saturation level and pulse rate. Information that is vital to have prior to starting any exercise regimen and just as important to have as the workout progresses and then ends. With the Pulse Oximeter, users can track and quantify the results of their efforts. Sturdy enough for hospitals, this Pulse Oximeter is the ideal tool for home. Designed especially for children as it features a colorful, smiling character on it that kids will love. The Pedal Exerciser lets kids "bike ride" again, gaining all the cardio-vascular benefits that bike riding offers without ever leaving the house. Arriving fully assembled, users just need to add the tension knob to get pedaling and start breathing easier. On the floor or the table-top, the Pedal Exerciser offers a terrific lower and upper-body workout that gets the heart pumping. The tension knob allows the difficulty to be customized and adjusted as children get stronger and continue to recover. Please note, the Pedal Exerciser has a weight capacity of 150 lbs. The tape measure is versatile in use. Ideal to be used in measuring any swelling or edema that are present in the extremities or to track progress with walking or other exercises. It features readings in both inches and centimeters with a maximum length of 60". When COVID-19 is in the rear-view mirror and patients are ready to begin the recovery process, this P.A.C.E.R. kit provides the starting line. The entire kit is Latex-free and safe for all. The Pulse Oximeter is completely portable. It is small, lightweight and comes with 2 AAA batteries and a wrist lanyard. The whole kit has been designed with children in mind. The Pedal Exerciser provides straps to ensure feet and hands stay in position during use and both the tape measure and pulse oximeter are pocket size and portable. The Pedal Exerciser and Pulse Oximeter should only be used under adult supervision. The Pedal Exerciser folds and unfolds at the push of a button, allowing the device to be stored easily or taken on the go without a problem.
