HealthyU Measures 8 ICU Vital Signs

7-lead ECG

With the integration of 3 chest leads and 4 finger leads HealthyU can display 7-lead ECG waveforms via its customized App. With Lead I and II along with Vector lead (V), Lead III, AVR. AVL, AVF leads are derived.

Heart Sound with a murmur indicator

Heart sounds are generated by the closing and opening of the heart valves, along with any abnormal shunts or flow in an affected heart . In a healthy individual, there are two normal heart sounds (S1 and S2) phonetically called lub and dub. Lub is the first heart sound. It is associated with the closure of the tricuspid and mitral valves at the beginning of systole. The second heart sound dub is associated with the closure of the aortic and pulmonic valves at the beginning of diastole.

Heart murmurs

A heart murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the heart valves or near the heart.

Murmurs can happen for many reasons, such as:

  • When a valve does not close tightly and blood leaks backward (regurgitation)
  • When blood flows through a narrowed or stiff heart valve (stenosis)
  • Murmurs are classified (“graded”) depending on how loud the murmur sounds with a stethoscope. The grading is on a scale. Grade I can barely be heard. An example of a murmur description is a “grade II/VI murmur.” (This means the murmur is grade 2 on a scale of 1 to 6).
  • In addition, a murmur is described by the stage of the heartbeat when the murmur is heard. A heart murmur may be described as systolic or diastolic. (Systole is when the heart is squeezing out blood and diastole is when it is filling up with blood.)

Lung Sound

Lung sounds are the noises produced by the structures of the lungs during breathing.

There are several types of abnormal breath sounds. The 4 most common are:

  • Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales). They are believed to occur when air opens closed air spaces. Rales can be further described as moist, dry, fine, or coarse.
  • Rhonchi. Sounds that resemble snoring. They occur when air is blocked or air flow becomes rough through the large airways.
  • Stridor. Wheeze-like sound heard when a person breathes. Usually it is due to a blockage of airflow in the windpipe (trachea) or in the back of the throat.
  • Wheezing. High-pitched sounds produced by narrowed airways. Wheezing and other abnormal sounds can sometimes be heard without a stethoscope.

Heart Rate or Pulse Rate

The pulse rate is a measurement of the heart rate. This is the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood. Taking a pulse not only measures the heart rate, but also can indicate the following:

The normal pulse for healthy adults ranges from 60 to 100 beats per minute. The pulse rate may fluctuate and increase with exercise, illness, injury, and emotions. Females ages 12 and older, in general, tend to have faster heart rates than do males. Athletes, such as runners, who do a lot of cardiovascular conditioning, may have heart rates near 40 beats per minute with no problems.

Pulse Oximetry (SpO2)

Oxygen saturation is the fraction of oxygen-saturated hemoglobin relative to total hemoglobin in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood.

Values can range from 92-100 % in a healthy individual, with lower levels associated with certain cardiac or pulmonary conditions.

The normal body temperature of a person varies depending on gender, recent activity, food and fluid consumption, time of day, and, in women, the stage of the menstrual cycle. Normal body temperature can range from 97.8° F (36.5°C) to 99°F (37.2°C) for a healthy adult.

Body temperature may be abnormal due to fever (high temperature) or hypothermia (low temperature). A fever is indicated when body temperature rises about 1 degree or more over the normal temperature of 98.6°F, according to the American Academy of Family Physicians. Hypothermia is defined as a drop in body temperature below 95°F. Clinical correlation needs to be determined to determine an illness.

Blood Pressure

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.

Respiration Rate

The respiration rate is the number of breaths you take each minute. The rate is usually measured when you are at rest. It simply involves counting the number of breaths for one minute by counting how many times your chest rises. Respiration rates may increase with exercise, fever, illness, and with other medical conditions. When checking respiration, it’s important to also note whether you have any trouble breathing.

Normal respiration rates for an adult person at rest range from 12 to 20 breaths per minute.
