The invention is a small patch with a peel-away adhesive surface that is applied to the skin of the subject, preferably near a large artery. For the Doppler monitor, the patch includes a pad formed of a conductive medium to enhance transmission and reception of ultrasonic waves. For the acoustic monitor, the pad has a sound focusing portion that permits entry of sounds and focuses the sounds toward a microphone, and the pad also has a sound insulating portion surround the sound focusing portion. The patch includes an integral power source. The Doppler patch has transmitters and receivers to send and detect reflected ultrasonic waves and a transducer to convert the reflected waves into an electrical signal. The acoustic patch has a microphone to detect the sound of a heartbeat and a transducer to convert the sound energy into an electrical signal. A processor analyzes the Doppler wave signals or the acoustic signals. A light indicates the presence and strength of a pulse detected from the Doppler wave signals or a heartbeat detected by the microphone. A speaker and a vibrator may also to indicate the presence and strength of a pulse or a heartbeat. The Doppler effect of waves reflecting from blood pumped from a heart is used to detect a pulse in the subject. The presence of a pulse or heartbeat is analyzed by the processor to determine the frequency and strength of blood flow or beating of the heart.
